Know What You Want
What to Ask Yourself Before Selecting a San Francisco Glass Company

With all the things glass can do for you, it can be overwhelming. Before you hire a glass company or glass artist, it’s important to be able to identify exactly what you want. Are you looking for new doors or windows for your home? Are you looking for new doors or windows for your home? Are you looking for custom-cut glass for a shower or tabletop? Do you want to add light and ventilation via a skylight or sun tunnel? Whatever you are looking for, whether for home or office, whether in the Tenderloin, the Sunset District, the Richmond District, Bernal Heights, the Mission District, North Beach, the Bayview District, Pacific Heights, or the Excelsior, the better you understand what you are looking for, the more you will be able to convey it. You might find it useful to draw up a list of questions and use them to narrow in on precisely what you want. Some questions might include the following.

  1. Do I want a Diamond Certified company that is rated best in quality and backed by the Diamond Certified Guarantee?
  2. Do I need custom doors for my new shower enclosure?
  3. Am I looking for a custom glass table top?
  4. Do I want a skylight? Am I concerned about how I will control heat or cold if I do put in a skylight?
  5. For my auto, do I have cracks that I think will spread or other damage to my windows or mirrors?
  6. Do I need new windows?
  7. Do I want doors with glass? If so, are they interior or exterior doors?
  8. If I get windows, am I interested in dual-pane or triple-pane?
  9. If I am looking for new windows, do I want wood, aluminum, or vinyl?
  10. Is my bathroom dim, and would a sun tunnel help lighten it up?

What To Ask In Person
Questions for When You Talk to Your San Francisco Glass Company in Person

You and your San Francisco glass company representative may not actually meet in person. Sometimes all the work can be done over the phone. Other times, you will go in to select a specific glass that you want. Or you make work with a glass artist to get exactly the piece you want. You are likely to meet auto glass representatives in person, at least to make access to your car possible. No matter what your needs in the Tenderloin, the Sunset District, the Richmond District, the Mission District, Bernal Heights, the Richmond District, North Beach, or the Bayview District, if you do meet your glass company professional in person, you may want to already have a list of questions that you can ask. With a list drawn up, you won’t feel flustered, put on the spot, or forget the questions you want to ask.

  1. Do you have textured glass samples that I could look at?
  2. For auto glass professionals: this crack is about five inches. It’s on the borderline of the rule of thumb to replace when the crack is six inches. Do you recommend repairing or replacing it?
  3. If I have an independent artist prepare glass work for my door or window, what is the process for getting it installed in the door or window? Is this a process you have done before?
  4. I like this door, but it is marked for interior use only. Can I use it for my patio doors?
  5. For sun tunnel professionals: I want to get some more light into my bathroom, but I can’t open the roof right above it. Is a sun tunnel appropriate here?
  6. For auto glass professionals: can you tell me the kind of training you have and if you have any certifications?
  7. For auto glass professionals: how long will the repair take and how soon can I drive my car?
  8. For window professionals: looking at the existing windows, and before we mention price, what kind of replacement window material would you suggest?
  9. For skylight professionals: if I install a skylight in this room, what is the biggest it could be?
  10. I am looking at the various doors you have. I like this door design in general, but I would like the glass to be different. Is that possible?

  • What To Ask References
    Questions for References

    It’s best to choose a Diamond Certified glass company 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 San Francisco and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. 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.

    1. If you replaced your windows, how long ago did you do it? Did you notice that your energy bill went down after you put the windows in?
    2. If you got your windshield repaired, did you feel pressure from the company to get it replaced instead?
    3. How much help with the insurance process did your auto glass company provide?
    4. Did you have any leakage or other problems after your windshield was replaced?
    5. If you replaced your windows, what kind did you put in? Wood, clad wood, aluminum, vinyl? Did you have any special reason for your choice?
    6. What did you have the glass company do for you?
    7. Were you satisfied with the work the glass company did? Why or why not?
    8. If you changed your windows, did you notice improvements in your own comfort in the rooms –were there fewer drafts, did you feel less cold coming off the windows when you stood near them?
    9. If you ordered a custom size for your shower doors, was the glass cut to the proper size? Or were there problems during installation.
    10. When you had the custom-cut glass, were there any marks left on it from the fabrication? If so, was the company skilled at placing them so they didn’t show?

  • Review Your Options
    Find and Hire a Good Glass Company in San Francisco

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    Your choice of glass company … So before deciding on the best glass company in San Francisco for you, it’s important to consider the following questions.

    6. Does your window provider give good information on whether a gas should be used in a double-pane window? Does the company demonstrate knowledge of the local climate and what is appropriate for it?
    7. Does the glass company offer the level of customization that you need? For example, will it cut custom sizes? If you want artwork in your cabinet doors, is that available from the glass company?
    8. For window companies, is the company properly licensed by the state of California with a glazing contractor’s license?
    9. Does an auto glass repair or replacement shop conform with the ANSI standards for safe auto glass replacement?
    10. Does the door or window company provide sufficient information on the energy-efficiency of its products?

  • How To Work With
    Before Settling on Your San Francisco Glass Company

    A small amount of due diligence makes choosing a San Francisco glass company a bit easier. 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. Do you need to replace or repair a windshield? Do you want triple-pane or double-pane windows for your home in the Tenderloin, the Sunset District, the Richmond District, the Bayview District, the Excelsior, Pacific Heights, the Mission District, or Bernal Heights? Do you want wood or aluminum replacement windows? You may not know the answers to any of these questions. But capture all your questions so that you can ask them of your glass professional.

    It only takes a minimal effort to be prepared before you speak with your San Francisco glass professional. If you are dealing with an auto glass repair or auto glass replacement, know your vehicle’s make, model, and year, especially if it’s a question of replacement. Give some thought to whether you insist on OEM materials, or will you accept OEE materials? For windows, it’s a good idea to know what you currently have installed– wood, aluminum, vinyl. You – or your contractor – should know the dimensions of the windows to be replaced and how many there are. If you’re looking at doors, you should note whether they are interior or exterior. If you need custom work for a shower enclosure, tabletop, or mirror, know the dimensions you need.

    It pays to find out about the San Francisco glass company and its employees. Ask about the company’s training policy. Ask what credentials they hold and what standards they follow. For window installations, you will need a glazing contractor, which means they need a California license C17. If you need auto glass repair or auto glass replacement, find a shop that conforms to the ANSI auto glass replacement standard. They may also refer to this as the AGRSS standard.

    Once You’ve Chosen Your San Francisco Glass Company
    Once you know which San Francisco glass company to hire, keep the communication open and clear. Consider your own role. Make sure that everyone involved understands his or her own role. Are you as the customer just choosing what you like and allowing your contractor to handle the details of measurement and installation? Or are you making yourself responsible for measuring, etc.? No matter where your project is happening in San Francisco, whether in the Tenderloin, the Sunset District, the Richmond District, Bernal Heights, Pacific Heights, the Excelsior, or the Mission District, confusion about responsibilities, which stems from poor communications, is one of the most certain ways to have a frustrating project.

    Be clear about the services you expect from the San Francisco glass company. Are they only providing a product? Or are they also installing it? Or is your own contractor doing the installation? What are the provisions if something gets damaged during transit or installation? Do not fail to get a written estimate and contract from the San Francisco 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.

    Methods to Make the Job Progress More Smoothly
    Your efforts are not unappreciated in making the project go smoothly. Make yourself available as necessary. Your auto glass repair person will probably not need you for the entire session, but the repair person may need you to open up the car, to inspect the damage. Similarly, whenever construction is being done on your house, you should always be available to answer questions and respond to questions promptly to prevent unnecessary delays.

  • Be a Good Customer
    How Can You Be a Good Glass Company Customer?

    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 San Francisco 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 San Francisco, 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 San Francisco 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 The Work
Verify the San Francisco Glass Company’s Work Against Invoice

Your written contract or invoice must be detailed enough that you can use it to be certain that the materials and labor were delivered as specified to your house, whether in the Tenderloin, the Sunset District, the Richmond District, the Mission District, Bernal Heights, or North Beach. If the glass company is only providing materials, such as windows or doors, make sure the delivered product matches what you ordered, that all the pieces are there, and that it was delivered on time. If the glass company is also providing labor for installation, be sure the installation is completed as designed. If not, be sure there are written changes that capture the variances from the design. Check that the timeline was maintained, or that there are written agreements that the timeline will vary from the original.

When it comes to auto glass repair or replacement, be sure the affected window or mirror was fixed. Check that the right material was used. If you wanted OEM parts, make sure you got them – look for logos and designs that match the originals. Over time, check for leaks or other problems with replaced windows.

Written Warranties
Ask Your San Francisco Glass Company for Warranties

Ask for warranties for both the workmanship and the products that you receive. Doors, windows and the like have warranties from the manufacturer. Check to see how long the warranties last and what they cover and what they exclude. For example, a window manufacturer is probably not warranting against baseballs.

No matter whether the products and the labor come from a single company or from different companies, you need to check the workmanship’s warranty as well. For example, some auto glass repair shops will give a warranty for the life of the car. Find out if that warranty is available only at the local shop, or if there is a network of shops that participate. You may want to find out if the warranty transfers if ownership of the car transfers.

Many contractors 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.

The most critical thing when you are getting work done on your house or vehicle in San Francisco, whether in the Tenderloin, the Sunset District, the Richmond District, Bernal Heights, the Mission District, the Excelsior, or Pacific Heights, is to be sure that you have the warranties for the product and the labor.

Top 10 Requests
Top Service Requests

Glass can be used across your house. 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 San Francisco, taking yourself from the Tenderloin, the Sunset District, the Mission District, Bernal Heights, or the Richmond District, or to other areas like North Beach or Nob Hill. 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.

Insulation
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.

New Cabinet Doors
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.

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.

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 Doors
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.

Auto Glass
Auto glass is not limited to your windshield. Consider all the other windows in your car, especially if you have a moon roof or panoramic roof. Also think of all the mirrors you need in your car, some with special reflecting abilities that make objects seem nearer or farther away.

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.

New Windows
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.

Windshields or Windscreens
Visibility is probably the most critical thing you need when traveling in your car, followed closely by stopping power. A cracked or dented windscreen can hamper your field of vision. It also weakens the glass, threatening to allow it shatter at any unforeseen moment. You’ll need to fix or replace a broken or pitted windshield.

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.

 

Top 10 Brand Requests
You will not always be able to find many national brands for all glass items. But in some categories, it’s possible to narrow down to the most popular brands. Below you will find some of the more popular glass brands – mostly for windows, and mostly for residential use. Your San Francisco glass shop will probably carry or be able to easily obtain most of these brands. At other times, your needs will be more specific, and your glass company, whether in the Tenderloin, the Sunset District, Bernal Heights, the Richmond District, the Mission District, Pacific Heights, or the Excelsior will actually provide glass specifically measured for your use.

Simonton
The Simonton windows are vinyl.

Vistawall
The Vistawall windows are aluminum.

Fleetwood
Fleetwood offers a line of aluminum windows.

Velux
Velux offers commercial and residential skylights, as well as sun tunnels.

Milgard

Andersen Windows
Andersen is known for its line of wood-framed windows.

Frequently Asked Questions
FAQ for Local Plate Glass Installation Companies

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.
