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

By switching to energy-efficient windows, you can benefit in several ways, including:

• Save on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
• Decrease your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in San Bruno

Let’s go over the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, such as the location of your home, size, number of windows, material, type and more.

It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save San Bruno homeowners $440+ a year when replacing single-pane windows.

We advise getting free quotes from several window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

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

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In San Bruno, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in San Bruno

In our search to find the most reliable, eco-friendly window installers in San Bruno, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed several window installers in San Bruno and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve San Bruno so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

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

Warranty

As discussed, windows are a serious investment, so you’ll want to be certain 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

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