    How Installing Energy-Efficient Windows in Brentwood Saves You Money

    There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

    • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
    • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
    • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
    • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.

    Estimated Cost of Window Replacement in Brentwood

    Windows come in varying shapes, styles and purposes, so costs and services will vary remarkably based on your project. Below, we detail the typical cost and services that you can get from window installers.

    How Much Do New Windows Cost?

    Typically, Brentwood homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. This is because of the fact that window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

    With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Brentwood homeowners $579+ per year after replacing single-pane windows.

    Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

    What Services do Window Installers Offer?

    In regard to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

    Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has noticeable rot or deterioration. These installations are more involved and will increase the total cost. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

    If you’re still trying to decide which type of installation to get, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.

    How We Choose the Best Window Installers in Brentwood

    In our hunt to find the most reliable, eco-friendly window installers in Brentwood, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Brentwood area so you can find the best window installation company near you.

    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 choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

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

    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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

    Warranty

    Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Last but not least, we like to see companies that have been in the industry for a while. Window installation companies 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.

    Brentwood, CA Window Replacement FAQs

    How much does a window install cost?

    The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

    What are the kinds of windows?

    The most common kinds of windows for homes are double-hung and single-hung windows, awning windows, transom windows, casement windows, slider windows, bay windows and picture windows.

    When do I have to use a window installation company?

    Unless you have experience with home improvement projects 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 a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.

    How do you know it’s time to replace your windows?

    Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.

    How long does it generally take to install windows?

    Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that have to be installed.
