    How Installing Energy-Efficient Windows in Clayton Saves You Money

    By switching to energy-efficient windows, you and your family can benefit in several ways, such as:

    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
    • Save on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $579 annually on your energy bills in Clayton.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
    • Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.

    Estimated Cost of Window Replacement in Clayton

    Let’s go over the cost of updating your windows and the kinds of services offered by installers.

    How Much Do New Windows Cost?

    Generally, homeowners in Clayton can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost varies depending on several factors, like size, material, type, the location of your home, number of windows and more.

    With windows, efficiency is one of the most important factors for most homeowners. Efficient 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 many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Clayton homeowners $579+ a year after replacing single-pane windows.

    We advise requesting free quotes from several window companies to find the one that works best for you.

    What Services do Window Installers Offer?

    The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?

    Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old 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.

    Your window installation company should be able to help you decide what’s best for your needs. In Clayton, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check your frames and window sills.

    How We Choose the Best Window Installers in Clayton

    In our search to find the most reliable, eco-friendly window installers in Clayton, EcoWatch examined many companies before deciding on these. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:

    Service Area

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

    Work Quality

    We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

    Customer Reviews

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

    Cost

    This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

    Warranty

    Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    Clayton, CA Window Replacement FAQs

    What is the average cost to install new windows?

    The typical cost to install one window ranges from $450 to $650. There are several factors that influence the price, which include local labor costs, your property’s location, how energy-efficient the windows are, the materials used in designing the windows, the number of windows and styles and sizes of windows.

    What are the different types of windows?

    There are various types of windows you can get for your house, such as casement windows, picture windows, bay windows, awning windows, transom windows, slider windows and double-hung and single-hung windows.

    What do window installers do?

    Window installation professionals cover the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.

    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 open or close, they may be in need of replacement.
