20 Best Window Companies in Davis, CA (2025 Reviews)

How Installing Energy-Efficient Windows in Davis Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, including:

• Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Davis, that’s about 117 pounds per year on average.
• Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $622 annually on your energy bills in Davis.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Davis

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

How Much Do New Windows Cost?

Even though the national average cost to replace a single window is around $600, it can range from $200 to $1,200. Costs will differ significantly depending on your location, the quality of your products, the current condition of your home and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Davis home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Another factor that affects the total cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has significant damage. Because these installations are more involved, they will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Davis

EcoWatch differs from other reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included on this list to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, quality of installation, cost, quality of parts, professionalism and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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