How Installing Energy-Efficient Windows in Sonoma Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could help you:

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Sonoma

Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you'll find from window installers.

How Much Do New Windows Cost?

Typically, Sonoma homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. But costs will vary considerably depending on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $418 a year on your energy bills in Sonoma.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the whole window, including the trim, sill and frame. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're still debating which type of installation you need, you can talk to your installer and get their recommendation. The decision mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Sonoma

The EcoWatch Reviews team is different from most reviewers since we assess these companies through a sustainability lens. We've decided to assess the best window installation companies in Sonoma mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Sonoma area so you can find the best window installation company near you.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Sonoma, CA Window Replacement FAQs

How much should a window install cost?

The typical cost to replace a single window can range from $450 to $650. There are a variety of factors that influence the price, such as local labor costs, your property's location, the number of windows, how energy-efficient the windows are, the materials used in designing the windows and styles and sizes of windows.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

When should I use a window installation company?

Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer option.

How do you know it's time to replace your windows?

Windows typically have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.

Should I replace my windows all at once?

If you're upgrading your windows to save on your energy bills, replacing all of your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
