How Installing Energy-Efficient Windows in Brentwood Saves You Money

Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to consider making the switch:

• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Brentwood, that's about 117 pounds per year on average.

Estimated Cost of Window Replacement in Brentwood

Windows come in different shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you'll find from window installation companies.

How Much Do New Windows Cost?

According to our research, the average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost you is based on several factors, like number of windows, the location of your home, type, material, size and more.

It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Brentwood home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

What Services do Window Installers Offer?

The first step of a window replacement is to clarify whether you need a full-frame or pocket installation.

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the total 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 (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.

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

How We Choose the Best Window Installers in Brentwood

EcoWatch reviews differ from other reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

Since this is a guide for Brentwood, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Brentwood.

Work Quality

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

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most 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 warranty, quality of installation, professionalism, cost, quality of parts and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
