You must not start a project without a written contract or invoice from your local glazier. The document must be detailed enough that you can use it to verify that the new glass, installation materials and labor were delivered as specified.

When the glass company provides materials, such as new glass and replacement glass, make sure the delivered product matches what you ordered, that the count of delivered pieces is correct, and that the delivery was on time. If the glass company is also providing labor for installation, be sure the installation is completed as designed. If not, be sure to write down the changes that vary from the original design. Check that the timeline was maintained, or that there are written agreements that the timeline will vary from the original.

Get warranties for the new glass and for the glass installation services. No matter whether the products and the labor come from one or many local glass companies, you need to ask for the workmanship warranty as well as the product warranty. For the labor, or workmanship, most contractors supply a one-year warranty.

California has laws that, depending on the problem, allow you to make claims for a longer period. For example, if physical harm is caused by improper workmanship on your new glass or replacement glass, there is a virtually unlimited amount of time to ask for redress.

Also make sure you know how and when you can take advantage of the warranty. Find out if that warranty is available only at the local glass shop, or if there is a network of glass shops that participate. You may want to find out if the warranty transfers if you sell your home or the item with the new glass or replacement glass.

Above all, the most critical thing when you are getting glass work done in Sonoma County is to be sure that you have the warranties for both the product and the glass installation labor.

Glass products are in great demand. 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 Sonoma County, taking yourself to glass shops in Windsor, Santa Rosa, Rohnert Park, Healdsburg, or Petaluma, or to other areas like Guerneville or Sebastopol. 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.

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.

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.

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

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.

Insulation 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.

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.

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.

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.

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

Considering how critical glass in its many forms is to us, we should be able to talk with our glass companies about exactly what we want. Use the glossary to help you understand some of the terms your glass merchant may use that you may not be familiar with yet.

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.

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.
