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

How Installing Energy-Efficient Windows in Pleasanton Saves You Money

When you switch to energy-efficient windows, you may see some perks, such as:

• Decrease your carbon footprint: In Pleasanton, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you install energy-efficient windows.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
• Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Pleasanton

Windows come in all shapes and sizes, so costs and services will differ tremendously. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will add extra costs to your project.

Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Pleasanton.

Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because 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 installation services companies provide: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation you should get, 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 Pleasanton

EcoWatch reviews are different from most reviews since we’re examining these companies through a sustainability lens. We’ve evaluated the best window installers in Pleasanton mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, cost, warranty, quality of installation, professionalism and more.

Cost

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

Warranty

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

Years of Experience

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