20 Best Window Companies in Sunnyvale, TX (2023 Reviews)

How Installing Energy-Efficient Windows in Sunnyvale Saves You Money

There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• More efficient energy use in your household: Because the summers can get pretty hot in Sunnyvale, homeowners usually rely on their air conditioner a lot. Energy-efficient windows decrease the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
• Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Sunnyvale

Windows come in different styles, purposes and shapes, so costs and services will vary tremendously depending on several factors. Below, we go over the typical cost and services that you'll find from window installers.

How Much Do New Windows Cost?

On average, Sunnyvale homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at about $600. Costs will differ significantly depending on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window replacement company will be able to help you understand what's best for your needs. In Sunnyvale, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Sunnyvale

EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Sunnyvale and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Sunnyvale so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, warranty, quality of installation, quality of parts, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Sunnyvale's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Sunnyvale window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
