Just start ticking off all the places you use glass, and you'll be amazed. Not only is glass in our homes, it's in our cars and our places of work, too. It's probably even on your latest mobile device.

No matter where you live in Marin County, whether in San Rafael, San Anselmo, Novato, Larkspur, Mill Valley, Sausalito, Belvedere, or Fairfax or Ross, you'll find more instances of glass in your life than you'd probably expect.

So when you find you need new glass or replacement glass, be sure you're shopping at the right place. Many glass companies in Marin County specialize in new or replacement glass for windows and doors. Others provide custom shower doors, mirrors, or glass tabletops. You'll also find many examples of art glass producers who make items for display, either on their own or incorporated into a door, window, or cabinet. No matter what kind of glass you need, look for the right glass contractor in Marin County, and enjoy finding the right glass for your needs.

Glass for Marin County Homes

Around your Marin County home, glass is everywhere. On entering your house, you may be greeted by entry doors that have glass insets. Indeed, the glass may form the greater part of the door. Then, of course, you have windows throughout the house. You may have cabinets and showers that have glass doors. Your tables may be glass-topped. When choosing new glass or replacement glass, look for beauty and appearance, as well as safety and durability.

When it comes to glass in doors, many doors are already designed with the glass put in. In some cases, you may choose a custom glass design to be set in the door. You may choose to have glass that is tinted, or etched with a design that you choose. Sliding doors to the outdoors may be clear or may be bubble glass, or other textured glass that provides a degree of privacy.

Custom glass could also find itself serving several purposes in your home. You may have glass-topped tables. Or you may have a custom shower enclosure with glass doors. Or you may want a custom mirror. All of these are readily available from glass contractors in Marin County, whether in San Rafael, San Anselmo, Novato, Corte Madera, Mill Valley, Larkspur, Tiburon, Point Reyes Station, Belvedere or other towns.

The most important thing to remember when ordering custom glass is that the measurements must be precise. Typically, the measurements are supplied, then your local glass company either cuts and tempers the glass or sends the project to a glass fabricator. No matter the process, the cut must be correct. After the cut, the glass is tempered, meaning that it is heated and then cooled. Tempering changes the internal structure of glass. Tempered glass resists breaking more than glass that is not tempered, and even more importantly, when it does break, tempered glass breaks into rounded, bead-like pieces instead of sharp shards.

Be aware that the process used to temper glass may result in marks sometimes called tong marks being left on the glass. Ask if these will exist. If they will, the glass company you've hired should work with you to ensure they are inconspicuously placed.

It's best to choose a Diamond Certified glass company in Marin County because all certified companies have passed an in-depth ratings process that most other companies can't pass. If you want quality from a glass company in Marin County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified glass contractors. And you'll never be fooled by fake reviews. That's because all research is performed in live telephone interviews of actual customers.

If you can't find a Diamond Certified glass company 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 glass company. Keep in mind, though, that references provided to you by the glass company 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 customers to call that they know are 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.

  • What did you have the glass company do for you?
  • If you ordered custom glass shower doors, was the glass cut to the proper size?
  • Did you experience any problems during the glass installation services?
  • When you had the custom-cut glass, were any marks left from the glass fabrication process? If so, was the Marin County glass company skilled at placing them so they didn't show?
  • Were you satisfied with the work the glass company did? Why or why not?

Take the time to do a little homework before you hire your Marin County glass company. You need to decide what you're looking for and which companies can supply it. Once you've identified your basic need, think about all the questions you have.

Prepare before speaking with your Marin County glass professional. You or your glass contractor should know the dimensions of the replacement glass you need or how many pieces of new glass you'll need. If you are looking at new glass for doors, you should know if they are interior or exterior. If you need custom work for a shower enclosure, tabletop, or mirror, know the dimensions you need.

Verify the company's training policy and ask what credentials they hold and what standards they follow. For glass installations, you will need a glazing contractor, which means they need a California license C17.

Once You've Found Your Marin County Glass Company
Once you've decided on your Marin County glass company, keep the communication open and clear. Consider your own role. Make sure that everyone involved understands their own roles. Are you just choosing what you like and allowing your Marin County glass contractor to handle the details of measurement and installation? Or are you making yourself responsible for the success of your new or replacement glass?

No matter where your glass installation project is happening in Marin County, whether in San Anselmo, San Rafael, Novato, Larkspur, Fairfax, Tiburon, Corte Madera, or Mill Valley, confusion about responsibilities, which stems from poor communication, is one of the most certain ways to have a frustrating project.

What exactly do you expect from the Marin County glass company? Are they only providing the new glass or replacement glass? Or are they also installing it? Or is your own contractor doing the glass installation? What are the provisions if the glass plates get damaged during transit or installation?

You must get a written estimate and contract from the Marin County glass company. There should be clear information on the materials to be provided, any installation labor, if it is provided, timelines for delivery, and details of who will be working on the project if subcontractors are involved.

Steps to Take to Make the Glass Installation Job Go Along More Smoothly
The job will run more smoothly with a few assists from you. Make yourself available as necessary. Your glass repair contractor will probably not need you to be present for the entire glass installation, but they may need you to be present to review the new glass, inspect the damage and accept the glass repair services. Similarly, whenever construction is being done on your house, you should always be available to answer your glass contractor's questions and respond to their questions promptly to prevent unnecessary delays.

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

  • Be clear and upfront with the glass company. Let them know what you want from your glass company, 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 glass company in Marin County, restate your expectations and goals, and reiterate to the glass company representative your understanding of the agreement. Most problems with local glass companies occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
  • Ask your glass company 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 the glass. The work will move along more smoothly if your glass company can reach you for any necessary updates, questions or work authorizations.
  • When your contractor contacts you, return calls promptly to keep the glass company on schedule.
  • Pay for the glass company's work promptly.

Why would you want to be a good customer? Glass companies 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 may be more easily resolved.

Check to see how long the warranties last and what they cover and what they exclude. Whether the new glass and glass installation techniques come from one source or from different sources, you need to check the workmanship's warranty as well.

Find out if your new glass warranty is available only at the local glass shop, or if there is a network of local glass shops that participate. You may want to find out if the warranty transfers if ownership of your home or the item. When it comes to labor warranties, many glass contractors in Marin County will give a one-year warranty on their workmanship. California has laws that, depending on the problem, will apply for a longer period. For example, if physical harm is caused by improper workmanship, there is a virtually unlimited amount of time to ask for redress.

You can find a surprising number of uses for glass. You may find you need glass for residential projects, for commercial buildings, for your car, for optical projects, for medical and even for defense industry projects. No matter the kind of glass you need, you will find a glass company to suit you. You may have to head out for a little search in Marin County, taking yourself from San Anselmo, San Rafael, Mill Valley, Larkspur, or Novato, or to other areas like Belvedere or Sausalito. But in the end, you should be able to find a glass company that supplies just the glass you need decorative, insulating, or for any application you can think of.

Precision Glass
Precisely ground glass, with a specific thickness and surface roughness is used in an array of products. From vision optics, to medical devices, even to the infrared and night-vision goggles used by the military all require very specially ground glass.

New Front Door Glass
You may want glass sliding doors to open out onto a patio or deck. Or you may want a mostly wooden door, with some glass set into the door. This glass may be clear glass, or you may opt for tinted or art glass for your door. The options are really limited by your imagination.

New Cabinet Door Glass
Cabinets house both precious and ordinary items. Some want clear glass for cabinet doors, so that the treasures inside are displayed. Others opt for colored glass or stained glass, or other decorative ways to make the cabinet itself a work of art.

Insulating Glass
We often ask that our structural glass provide insulation. We want windows that will keep any heat or cooling inside, rather than allowing it to dissipate through a single pane of glass. The glass industry has developed special windows that meet this need, often by sandwiching an air space between layers of glass. Such windows also work to insulate us from noise transmission.

Mirrors
Mirrors run throughout our houses and businesses. Of course, you can always get a kit and silver a pane of glass yourself, but it's so much easier to seek out an experienced mirror maker and get exactly what you want.

Glass Repairs in Marin County
Glass repair is the repair of cracks, chips or other flaws in existing glass surfaces. Many glass contractors in Marin County offer glass repair services. This is often much less expensive than new glass or total glass replacement.

Decorative Glass
Decorative glass is usually used for display. It may be freestanding pieces like blown glass vases, bowls, sculptures, or the like. Or decorative glass may be found incorporated into windows, doors, or cabinets as stained or etched glass. You may be a glassblower yourself and looking for tools or classes on how to improve you glassblowing technique.

Replacement Glass
Replacement glass can be installed by a local glazier or glass company in Marin County.

Tabletops
Beautiful tables can be wrought from glass tops set into frames of wood or metal, or other materials. Tabletops sometimes need replacing, too, if they are scratched or otherwise damaged.

New Window Glass / Replacement Window Glass
New windows will allow you to replace cracked, shattered, broken, or outdated windows. Sometimes you change only the pane of glass. Other times, you may replace the glass and frame, since newer, more effective windows that provide better insulation are available.

Easy Steps To End Conflict with Marin County Glass Companies
You and your Marin County glass company can begin by trying to resolve the problem between the two of you. Your written contract or invoice should be detailed enough so that it is the primary tool for resolving any disputes. If you cannot resolve the dispute, you have a few remedies. For complaints about any contractor, including a glazing contractor, you can file a complaint at the Contractors State License Board (CSLB) Web site. Note that the Board is not primarily focused on restitution. If that's what you want, you will probably go to small claims court.

If you want to avoid court battles with glass contractors in Marin County, whether your claim originates in San Anselmo, San Rafael, Novato, Larkspur, Mill Valley, or Point Reyes Station, consider arbitration. You may be able to find an arbitrator that both you and the glass company can agree on. Or you might consider compromising with the glass shop, accepting a different product for a different price, perhaps, as one example.

Frequently Asked Questions
FAQ for Local Plate Glass Installation Companies

Q: Why choose a Diamond Certified Glass?...

Read More »
Expand

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

Q: When replacing my windshield or other auto glass, what is OE or OEE glass?
A: OE refers to “original equipment”, while OEE is an “original equipment equivalent. The OE is what comes with your vehicle, installed by the manufacturer. Though, of course, the vehicle manufacturer may source parts such as windshields from other companies, even in the original vehicle. An OEE glass will be of the same quality as the originally installed part, but it may be from a different manufacturer.

Q: What is AGRSS?

A: AGRSS is now called the Auto Glass Safety Council. It is an organization that was developed to help achieve safe auto glass replacement. The Auto Glass Safety Council is an accredited American National Standards Institute (ANSI) standards creation organization, which means it is allowed to define standards to ensure the best education and procedures, as well as product evaluation in the field of auto glass replacement. The ARGSS standard defines the best practices for the industry. You would want to look for auto glass replacement companies who are aware of it and comply with it. 

Q: Why is there water on the interior of my windows?
A: We are talking here about the water that forms on the interior side of a window, not any water that may form between the panes of a multi-pane window. The water is condensation from the reaction of cold air outside and warm air inside. Often, the condensation results because the interior humidity has been raised to take account of the dryer air that the cold brings. Reducing the humidity in the house should reduce the condensation.

Q: There is water between the panes of my double-glazed window. Is that a problem?
A: Double-glazed windows consist of layers of glass surrounding a cavity. Sometimes the cavity is filled with gas, other times with air and possibly a desiccant to dry out any moisture that may happen. If the moisture is in a place that you cannot reach it to clean it, this means that the seal between the window layers is no longer holding, and the windows should be replaced.

Q: When do I have to get the glass for my new shower?
A: Although when you get the glass for your new shower will vary based on your circumstances, it is often one of last pieces you get for your bathroom. Once the bathroom is mostly done, one approach is to measure the spaces where you will need the shower doors, then go to a glass company with the specification. The glass company will help you choose your glass – there is clear glass, but you might want to choose one of the more opaque styles of glass. Your glass company will also work with you to determine if you want any special edging on your glass. The specifications are then sent off to a manufacturer, and the glass is produced, ready to be installed. Of course, your contractor may do some of this work for you. But generally, you can leave glass selection till close to the end of your bathroom design and installation.

Q: What is Low-E?
A: Low-E refers to low-emittance. A low-emittance coating can be applied to glass and is almost invisible. The coating reduces the ability of heat to radiate through the glass. Thus, the glass admits plenty of light but not plenty of heat.

Q: If only one side of a dual-pane window is broken, why do I have replace the whole thing?
A: Dual-pane windows operate and are manufactured as a unit. The two sheets of glass are separated by a space. The space includes a desiccant to trap moisture. If even one side of the glass is broken, the unit is no longer a unit, the desiccant can absorb so much water that it becomes useless. Whenever any component of a dual-pane window is compromised – from glass to seal – the entire unit is compromised.

Q: Can you cut tempered glass?
A: The short answer to this question is no. If you try to cut tempered glass – because you have the wrong size, for example, the glass will shatter. Some claim that you can heat the glass to return it to its annealed state – the state it had before it was originally tempered, cut the glass, then re-temper the glass. .

Q: What is a panoramic roof?
A: Car makers are developing a panoramic roof. It is like a sun roof, but much larger. It brings light into the car. Some liken the panoramic roof in the car to the concept of indoor-outdoor living in the home. The panoramic roof brings the outdoors into the car’s cabin. In Europe, the panoramic roof is often fixed – it does not open. However, car makers have discovered that in America, buyers expect the panoramic roof to open.
