New windows are an investment in the comfort, appearance and value of your home. But your windows and the value they add are only as good as the Marin County window contractor you choose to install them.

Research is the key to finding the best window contractors in Marin County, including those in San Rafael, Novato, Mill Valley, San Anselmo and Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax and Ross as well as those serving smaller towns.

Whether you want to trade in your drafty windows for lower heating and cooling bills, swap those small windows with peeling frames for an improved view and aesthetic, or invest in beautiful and efficient windows that immediately increase your home's value, the first step in choosing a good window contractor is to decide what you want to gain from your new windows.

By having a specific goal, you're more likely to find the Marin County window contractor that meets your needs.

The Clear Choice for Commercial Window Installation in Marin County
Show-stopping storefronts and aesthetically-appealing commercial buildings in the larger Marin County cities such as San Rafael, Larkspur, Corte Madera, Mill Valley, Novato and San Anselmo have one obvious element in common -windows that are visually pleasing to the public outside and that make working and shopping more enjoyable inside.

But selecting and installing new windows for commercial use is a different process than choosing residential windows. Commercial materials are often stronger and more flexible to allow for eye-catching design and building stability, and products range from opaque reflective surfaces to windows specially-built for security.

While most window contractors in Marin County can provide windows for commercial buildings and storefronts, some contractors do more of this type of work than others. So choose commercial window contractors that have the skills and knowledge to help you make the best decision for your project. Factors to consider when choosing commercial windows include:

  • Cost
  • Security
  • Aesthetics
  • Energy efficiency
  • Air and water tightness
  • Structural and acoustical performance
  • Light, glare, view and thermal factors that increase employee productivity

When you've found experienced commercial window contractors that will help you consider all the important factors for your store or office window installation, follow the same steps for residential window installation to be sure you're hiring the best company for the job.

The Value of Researching Your Choices for Window Installation
Every Marin County window company claims to be the best. So how do you see through the self-promotion and find those contractors with proven records? There are several sources you can look to for more information, unbiased reports and information on past installations.

While it's best to choose a Diamond Certified company because they're rated Highest in Quality, that may not always be possible. If you're unable to choose a Diamond Certified window contractors in your area of Marin County, you can improve your chances of hiring a good window installer by checking out candidates on the Contractors State License Board website to ensure active license and workers' compensation insurance. Violations will also appear on their license record, so you'll know about recent infractions or serious customer grievances that have been processed by the state.

Then take time to verify company credentials. Good window contractors who are members of local organizations and window associations may offer better service, and you'll be able to see their past records, including complaints and legal action. Some local window contractors in Marin County have even earned certifications from window manufacturers as authorized distributors and installers who can simplify the entire process for you.

From start to finish, you're going to be spending days, weeks or even months dealing with your window contractor. Like with any working relationship, it's important that you work well together. So you'll want to consider the personal and professional qualities you want in a window installer. Traits such as promptness, good communication skills, honesty and cleanliness are important to many consumers, so make note of the kind of window contactor you want to hire and don't settle for less.

Be aware, though, that with some window installation companies in Marin County, including in the larger cities of Tiburon, Sausalito, San Rafael, and Novato the salesperson you buy your windows from may not be involved in the installation process. That means there's a chance the rapport you've built with them and the agreements you've made might not carry through to the rest of the job.

If you've been talking with a local window sales representative, you may want to confirm with them who will be your contact during the installation and how they can guarantee the promises made during the sales process will be kept by the installation crew.

Further Research on Window Contractors in These Major Marin County Cities: San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax and Ross
Now that you've done some initial research, talk with a few window contractors in your area of Marin County. That's easy if you live in one of the larger cities, including San Rafael, Fairfax, Novato, San Anselmo or Larkspur.

However, many window installers are willing to travel to other parts of Marin County, including the smaller towns of Belvedere, Almonte, Woodacre, Tomales, Terra Linda, Marin City, Greenbrae and Mission Rafael, and other smaller cities.

When you interview window companies, have a written list of questions and note the contractors' answers. Remember, though, that many window installation contractors will not provide estimates over the phone without seeing the job first.

But don't feel obligated to set an appointment for an in-home estimate if you weren't impressed with your initial contact with the window contractor. If the local window installers you've talked with don't meet your expectations or can't answer your questions satisfactorily, end the conversation and move on to the next window company on your list.

  3. What is my budget for home window replacement?

  5. Is there a specific design aesthetic or look I want from my new windows?
  6. Do I plan to live in this home long-term, or is it a rental property or a house I plan to sell?
  7. What characteristics do I want in a Marin County window contractor? (This could include communication skills, starting the job on time and sticking to the schedule throughout the job, specific warranties or guarantees, and follow-up service.)

This will keep you on track and ensure you get the answers you most need to make your decision. Be sure to keep a record of the contractors' answers.

It's best to choose a Diamond Certified window contractor because all certified companies have passed an in-depth ratings process that most other companies can't pass. If you want quality from a window company in Marin County and the greater Bay Area, you can have confidence choosing a Diamond Certified company.

Diamond Certified Company Reports for windows contractors, including verbatim customer survey responses and a complete table of capabilities, are available at www.diamondcertified.org.

If you can't find a Diamond Certified window contractor within reach, you'll have to do some research on your own. If you do, it's wise to call some references provided by your window company.

Keep in mind, though, that references provided to you by the window companies are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process.

That's because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customer references that they know were satisfied.

If you do call references on your own, specifically ask for a list of the company's 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied. Talking to these references can give you an insider's view on how the Marin County window contractors performed on previous jobs. So call several references and ask them specific questions about the contractor you're considering.

Here are some sample questions that can help you determine whether a contractor is a good fit for you:

  1. Were you satisfied with the window installation and the service from _(window company name)_?
  2. What was the type and scope of job they did for you (window replacement, window repair, whole house window installation, etc.)?
  3. Did the Marin County window contractor you hired complete the work on time?
  4. Did the contractor keep you up-to-date on the status of the project?
  5. Were there unexpected costs? If so, what were they?
  6. If you live in a smaller town such as Dillon Beach, Belvedere, Bolinas, Inverness, Santa Venetia or Stinson Beach, did they charge extra to travel to your home?
  7. Did the window installers show up on time?
  8. Did they clean up after finishing the window installation?
  9. If you need new windows in the future, would you use this window contractor again?
  10. Would you recommend them?
  11. Can I visit your home to see the completed window installation?

Your choice of window contractor impacts every part of your job, from the ease of the installation to how long your new windows last.

So before deciding on the best window contractor in Marin County for you, it's important to consider the following questions.

  1. Can the window contractors meet your needs in terms of scheduling, products and installation preferences?
  2. Are the Marin County window contractors knowledgeable on the products they offer? Can they tell you which products best suit your needs and why (i.e. aluminum windows, insulated windows, vinyl windows, energy efficient windows)?
  3. Is the window installation company sensitive to your budget? Can they offer various products that fit your resources? Most contractors will give you bids for Good, Better and Best options that include a choice of product, design, prices, brand names and services.
  4. Do the window contractors in Marin County offer warranties in the event of a product failure or installation error? Will they put these guarantees in writing?

It's also smart to note your own expectations, realizing that some may not fit well with the project. For example, it may not be realistic to expect a consistent schedule or a quiet worksite when having new windows installed.

You're most likely to be satisfied with the process when you talk with your contractor before the job begins and discuss realities and expectations from both your view and your window contractor's.

In this buyer's market, you might be surprised to find you're not the only one who is interviewing and selecting potential candidates. Marin County window companies, including those in the larger cities of Mill Valley, Larkspur, Fairfax, Novato, San Rafael and San Anselmo and even some in the smaller towns can also be selective about which jobs they accept. Bids take time and expense to prepare, and many contractors have lost money and faced difficult dealings with unreasonable homeowners. That can make them choosy about with whom they do business. So it's reasonable that some local window contractors show a lack of interest or don't respond to all job requests.

There are some ways you can encourage good window contractors to bid on your job.

  • Be honest about the fact that you're accepting other bids and interviewing other window contractors, but assure them you're gathering three bids, not dozens.
  • Look for good value, not just the lowest price. The first question that contractors often hear is about price, so it's important to show them you understand the importance of quality and overall value.
  • Shop among local window contractors in Marin County. Most like to stay in the local area, as it allows them to provide better service in a timely fashion. It also shows the contractors you're serious about quality products and installation, as some fly-by-night contractors travel long distances to install cheap products that local contractors may not be able to compete with price-wise.

Get the Most Out of Your Deal with Local Window Contractors in Marin County
You've finally found the perfect Marin County window contractor that meets all your requirements. Now is the time to ask your window installer for a contract that includes written confirmation of price, quality and timing for the entire job. They should also be willing to provide you with a written timeline that covers the job start date, major milestones and intended completion date along with areas of specific concern.

The contract you sign with a Marin County window company should protect you and your property as well as your contractor's interests. For this reason, never sign a blank or incomplete estimate. Read the entire contract and understand the terms before you sign it. And don't be afraid to write in your own requests or put in writing the verbal agreements you've made with your representative.

For instance, start and end dates are important, but there are factors you and your installer can't control, such as the weather. That's why it's a smart idea to add a no-later-than clause to your contract. This stipulates the date by which all work must be completed. Even if inclement weather or problems with the products delay installation, this clause will give you assurance that your job will be finished on time. If a quick turnaround is important to you, you may want to consider adding a bonus for early completion to your contract as well.

Confirm any warrantees at this time, as some window installers in Marin County only guarantee certain brands or installation techniques. Also verify that manufacturer warrantees apply to the windows you're having installed.

Don't forget about related issues that may not be covered by a standard contract. For example, regardless of how careful your window installer promises to be, crushed flowers, damaged shrubs and rutted lawns are often unexpected hazards that come with hiring a window contractor in Marin County. But you can protect yourself and your property by being proactive.

Before work begins, ask the job supervisor to accompany you on a pre-work inspection to determine the original condition of the property. List or photograph your landscaping and property before the work begins, and talk with your contractor about reasonable expectations for protecting your home and yard during the window installation process. When you've reached an agreement about the condition of the property, both you and the contractor should sign and date the document. After the work is done, do a final inspection together to confirm your expectations were met.

It's the window company's responsibility put in quality windows using the best possible installation techniques. But you play a big part in the success of your new window installation, too. Here are a few simple steps you can take to be a good customer when hiring a Marin County window contractor.

  • Be clear and upfront with the Marin County window contractor or window company representative. Let them know what you want from your windows, the long-term outcome you're expecting and specific ways they can satisfy your expectations.
  • Remember, a friendly smile goes a long way.
  • Before you hire a window contractor in Marin County, restate your expectations and goals, and reiterate to the window company representative your understanding of the agreement. Most problems with local window contractors occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
  • Ask your window installer if you should call to check on the progress or if he will call you with updates.
  • Be sure your service representative has a phone number where they can reach you at all times while they're installing your new windows. The work will move along more smoothly if your window company can reach you for any necessary updates, questions or work authorizations.
  • When your contractor contacts you, return calls promptly to keep the window installation on schedule.
  • Pay for the new windows and installation work promptly.

Why would you want to be a good customer? Window installation contractors in Marin County appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems more easily resolved.

When the work is completed, most good window contractors in Marin County will give you a written invoice that details all the work done. This invoice usually includes:

  • The name and physical address of the window contractor.
  • A list of all window installation work performed.
  • An itemized list of all new windows or window replacement parts.
  • The total window installation cost, including the amount due for labor.
  • Any applicable warrantees or guarantees provided by the window manufacturers or the window installers.

It's smart to compare the written invoice to the work that was actually done. Ask your window company representative to walk through the job with you and show you the window repairs and installation. Check this work against the invoice.

Your window company should be willing to talk you through the process and give you any special instructions for operating your new windows and maintaining them over the life of the product. If you have questions about what work was done or how the installation was completed, this is the time to ask.

Homeowners' Top Requests for Marin County Window Contractors

Read the paragraphs below for the definition of the most popular types of window repairs and window replacement services in Marin County.

Read the paragraphs below for the definition of the most popular types of window repairs and window replacement services in Marin County.

New Windows
New windows are usually installed in new construction and remodels. They differ from replacement windows because they have a nailing fin along the outer frame and are nailed in from the outside of the home before siding or exterior trim is installed.

Replacement Windows
When existing windows deteriorate, replacement windows are often the solution to upgrade efficiency, security and appearance. Marin County window contractors usually install replacement windows in existing window spaces, using the existing trim and cladding. Drop-in replacement windows are designed for minimal disruption of the existing structure and are often the least expensive option.

Storm Windows
Storm windows are added to existing windows to increase efficiency. They can be permanent or temporary windows mounted externally or internally to existing windows.

Bay Windows
Bay windows are popular requests in Marin County because they project outward from the main walls of a home. This creates a larger living space or the illusion of a larger room depending on the type of bay window. Bay windows also add architectural interest and increase the amount of natural light that flows into a room.

Energy Efficient Windows
Energy efficient windows are often designated with an Energy Star label. These windows are known to drastically reduce energy bills. Most energy efficient windows are insulated and protect against heat loss and gain, maintaining indoor air temperature.

Casement Windows
Casement windows are those that are attached to the window frame by hinges located on the side of the windows. (Windows that are hinged at the top are called awning windows, while windows attached at the bottom are hopper windows.) Casement windows may contain leaded glass and often open inward.

Aluminum Windows
Known as strong, durable and easy-to-configure, aluminum windows are often used to showcase beautiful views. They are also a less-expensive option in homes and light commercial buildings. Aluminum windows are not traditionally the most efficient, but more recent aluminum windows are more energy efficient than previous designs.

Window Repair
Window installers in Marin County are often asked to repair old windows and windows that have been broken. Some contractors specialize in repairing and restoring old windows to maintain historic homes. Others repair window frames and provide routine maintenance for modern windows.

Vinyl Windows
Vinyl windows are a favorite of Marin County homeowners in San Rafael, Sausalito, Mill Valley, Ross and other cities because they are inexpensive, durable, energy efficient and nearly maintenance-free.

Double-hung Windows
Perhaps the most popular type of window, double-hung windows consist of upper and lower window sashes that slide vertically in side window jambs. They have a maximum opening of one-half the total window area.

Top 10 Requested Window Brands
Many homeowners and window installers in Marin County have favorite window brands. The most-requested window brands are listed below.

Easy Ways to End Conflicts with Marin County Window Installers
The best strategy for avoiding problems is to carefully choose a qualified window contractor from your local area of Marin County who strives for customer satisfaction.

But what do you do if something goes wrong despite your best efforts? The most direct route is to try to resolve the problem openly with the contractor. Most local window contractors are professionals who want to uphold their reputation, so they have a vested interest in keeping customers happy.

When talking with your window installer, remember these tips:

  • If you have a concern or a complaint about your new windows or the installation work, talk to your contractor immediately. Don't wait until the job is done to voice your concerns.
  • Review the contract specifications with your windows contractor and try to verbally resolve the problem.
  • Document your complaint in writing and your contractor's response in case you need it for future use. Take photos if your concerns are with the materials or workmanship.
  • Set a deadline with your window contractor for resolution, and let them know you're willing to compromise and negotiate a mutually-beneficial agreement.
  • You may withhold payment until the dispute is resolved.
  • If you do not get an appropriate response, consider calling a local building inspector or hiring your own expert to evaluate the problem.
  • Fire the contractor as a last resort, as this can lead to work delays and expensive lawsuits.
  • File complaints with the Contractors State License Board and other consumer organizations.
  • Contact your state attorney general.

Frequently Asked Questions
Frequently Asked Questions for Local Window Contractors

Q: Why choose a Diamond Certified Window Company?...

Q: Why choose a Diamond Certified Window Company?
A: Diamond Certified ends the guessing game by helping you choose a window contractor with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only window companies rated Highest in Quality earn the prestigious Diamond Certified award. Most local window companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with in-depth and ongoing research and ratings. And your window installation purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified window company for your new windows.

Q: How will replacing my windows improve the comfort of my home?
A: New windows will make your home quieter and more secure. Depending on the windows you choose, you may also notice a marked difference in the temperature of your home as well. Double-paned windows are insulated to keep out the heat of the summer, and maintain heat during the winter.

Q: Will replacing my old windows save me money?
A: Old windows and windows that are improperly installed are the biggest cause of energy loss in the home, costing you money every day. New windows will save you money over the life of the window by cutting heating and cooling costs. Some homeowners report savings of up to 30 percent on their utility bills after installing new windows. New windows can also increase the life of your furnishings and carpeting by keeping out harmful rays of the sun, so you’ll save money by not having to replace expensive furnishings.

Q: If I decide to sell my home, will new windows and doors increase the value?
A: Yes. New windows are one of the best home improvements you can make in terms of the return on your investment. Realtors report that Bay Area homes with new energy-efficient, maintenance-free windows can see return of up to 114% in resale value.

Q: What window materials do I have to choose from?
A: Your choices for new windows are wood, vinyl, steel, aluminum, fiberglass and composite. You’ll see the sash and the frame (the visible outer parts of the window installation units) from the inside and outside of your home, so it’s important to choose the material that gives you the look you want. It’s also important to select the material that has the attributes you’re looking for. For example, metal window frames can conduct heat and cold, so they may not be as energy efficient as wood or vinyl windows. Additionally, some window frame materials can be painted to match your home’s exterior or interior, so that may be an important consideration.

Wood windows can be painted and stained. The downside to wood windows is that they must be regularly maintained. However, most wood windows are made from rot-resistant woods. When maintained correctly, they can last as long as metal windows.

Vinyl windows are inexpensive, energy efficient and durable. And while they cannot be painted, they come in a variety of colors and are virtually maintenance-free.

Steel windows are rarely used in residential buildings, as they aren’t as energy efficient as other types of windows and the window must be painted so they don’t rust.

Aluminum windows are strong and durable. They also allow for greater flexibility in window design. However, they aren’t as energy efficient as other types of windows.

Fiberglass windows are durable, efficient and strong. The frames can be painted to match any home. Because of their quality and durability, fiberglass windows are some of the more expensive widows on the market.

Composite windows have sashes and frames made from more than one type of material. This allows the manufacturer to customize the windows to fit the exact needs of the consumer. Some composite windows have a wood interior that can be painted with more efficient material such as vinyl or aluminum that better resists weather. New composite windows can be made from recycled wood and plastic that can be painted but resist rot.

Q: How do I know which kind of windows are the best choice for me?
A: Your local window contractor will help you decide which manufacturer, style and material of windows is the best fit for your budget, home and aesthetic preferences. It’s wise to make a list of what you’re looking for in new windows so that your window installer can help you decide which windows best fit your needs.

Q: How much do new windows cost?
A: The cost of new windows greatly varies based on the type of windows you select, the manufacturer and the number of windows you have installed. It also depends on whether you’re having replacement windows installed (windows that are custom ordered to fit in place of your existing windows) or whether you’re having new window frames and jambs installed as well. Your window contractor can provide an estimate based on your specific requirements.

Q: How long will it take to install new windows?
A: That depends on the size and scope of your job. A simple window installation may take an hour, while installing new windows throughout an entire home may take several days or a week. Your window contractor should be able to give you an estimated time frame on your specific project.

Q: Can I put in new windows myself?
A: Like with many home improvement projects, you can replace your windows yourself. However, for most window replacement jobs, it's better to hire a skilled professional. Professional window installers know the best materials and installation techniques for the job. And because they have so much experience removing old windows and installing new ones, they can do the job faster and much more effectively than can most homeowners.

Q: What about getting my new windows from a home improvement store?
A: Most home improvement stores sell new windows, and many advertise low prices. But you may sacrifice selection and quality by getting your new windows from a home improvement store. Most have a smaller selection, so you may not get the windows that best suit your home and your needs. And if they sell discount windows or off-brand products that are less expensive, you run a greater risk that the manufacturer will go out of business, leaving any warranties null and void. Another factor to consider is that most home improvement warehouses don’t provide installation or they rely on subcontractors. That means you can be caught between the retailer, the manufacturer and the installer if there are any problems with your windows.

Q: I’ve heard it’s important to hire a local window contractor that is an authorized installer. What does that mean and why should I look for a certified window installer?
A: Most major window manufacturers certify window contractors whom they have trained to install their specific products. These authorized installers also sell new windows and replacement windows. You’re likely to get a better installation, and some manufacturers even offer extended warranties on products their installers put in. And if something goes wrong later, you can avoid added hassle by hiring the same contractor for the purchase and installation of new windows one company will be responsible for the work.

Q: What happens if someone gets hurt while working on a job on my property?
A: When you hire a legitimate window contractor with the correct license, liability insurance and workers’ compensation insurance, you won’t have to worry. Under workers’ compensation insurance, every employee of the company is covered in the case of accident or injury. You will not be held responsible for damages. Make sure you ask your contractor to show you a copy of their active workers’ compensation policy.
