How Installing Energy-Efficient Windows in Brentwood Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing 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.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
  • Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help lower that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Brentwood

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

How Much Do New Windows Cost?

According to our market research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. This is because window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

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

We recommend requesting free quotes from several window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first step when considering an installation is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're not sure which type of window installation service you should get, your installer can advise you. Typically, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Brentwood

In our hunt to make your home improvements easier and more eco-friendly in Brentwood, the EcoWatch team chose the above companies as the top window installation companies in the city. We've reviewed the best window installation companies in Brentwood mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

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

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive things to say about their experience with a certain company, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Brentwood, CA Window Replacement FAQs

What is the average cost to install windows in a home?

The typical cost of replacing one window ranges from $450 to $650. There are many factors that affect the price, including your property's location, how energy-efficient the windows are, local labor costs, styles and sizes of windows, the number of windows and the materials used in designing the windows.

Which kind of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
