20 Best Window Companies in San Gabriel, CA (2025 Reviews)

How Installing Energy-Efficient Windows in San Gabriel Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
• Save on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.

Estimated Cost of Window Replacement in San Gabriel

Each window replacement company provides various services and has varying costs depending on several factors.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which carry a higher price tag.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save San Gabriel homeowners $509+ a year when replacing single-pane windows.

Requesting free quotes from several companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

When it comes to window installations, there are typically two kinds that your installer will offer: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window replacement company should be able to help you understand what’s best for your needs. In San Gabriel, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in San Gabriel

EcoWatch differs from other reviewers, as we’re examining these companies through a sustainability lens. We have assessed the best window replacement companies in San Gabriel mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for San Gabriel, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in San Gabriel.

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you get. 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

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

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 providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, 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

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