    How Installing Energy-Efficient Windows in Oakley Saves You Money

    When you switch to energy-efficient windows, you may see some perks, including:

    • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
    • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
    • Save on power bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save about $579 annually on your energy bills in Oakley.
    • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.

    Estimated Cost of Window Replacement in Oakley

    Let’s take a look at the cost of updating your windows and the kinds of services offered by installers.

    How Much Do New Windows Cost?

    The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These amounts vary based on the specifics of your installation, like size, the location of your home, type, number of windows, material and more.

    It’s important to remember that windows with the best 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 Oakley homeowners $579+ a year when replacing single-pane windows.

    Something else that influences the total cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

    What Services do Window Installers Offer?

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

    A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

    Your window installation company can recommend the best type for your project. In Oakley, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

    How We Choose the Best Window Installers in Oakley

    The EcoWatch Reviews team is different from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

    Service Area

    This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

    Work Quality

    We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, cost, quality of parts, quality of installation, warranty and more.

    Cost

    This one is a give-and-take: as with most services, cheap window installers may not provide the most quality service. Still, 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 previously, windows are a significant investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

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

    Oakley, CA Window Replacement FAQs

    How much should window installation cost?

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

    What are the different kinds of windows?

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

    What services do window replacement companies do?

    Window installers visit your house to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.

    When is the best time of year to replace windows?

    Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.

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

    Windows typically last about 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them looked at by an expert to determine if they need any repairs or replacements.
