Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

A guide on the best window replacement companies in Clayton may not seem like the most interesting article on the EcoWatch site, but trust us, windows have more of an impact on your life than you might realize. If your house has traditional, outdated windows, your HVAC system could be working overtime to heat or cool your home. This means higher electricity bills.

Installing new, efficient windows on your property can help you save money every month on your electric bills — and you can help the environment, too.

Efficient windows are especially important in Clayton, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $376 per year.

    Clayton Window Cost Calculator

    Calculate how much you can expect to pay for window installation and replacement in Clayton, MO using our customized window cost calculator.

    Estimated Window Cost:
    161 homeowners have requested a free estimate in the last 3 days.

    Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

    How Installing Energy-Efficient Windows in Clayton Saves You Money

    By switching to energy-efficient windows, you can benefit in several ways, including:

    • Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that amount, which helps you save $376 a year on your bills.
    • Reduce your carbon footprint: In Clayton, you can lower your indirect greenhouse gas emissions by about 763 pounds per year when you switch to energy-efficient windows.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
    • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

    Estimated Cost of Window Replacement in Clayton

    Windows come in various purposes, styles and shapes, so costs and services will vary remarkably depending on your project. Below, we go over the average cost and services that you’ll find from window replacement companies.

    How Much Do New Windows Cost?

    According to our research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which have a higher price tag.

    Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $376 a year on your energy bills in Clayton.

    Another factor that influences the total cost is the material you pick for your frame. Aluminum frames are generally the least expensive 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?

    The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

    Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the total window, including the sill, trim and frame. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

    Your window installer should be able to help you decide which type of installation you need.

    How We Choose the Best Window Installers in Clayton

    EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. We have evaluated the top window replacement companies in Clayton mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

    Service Area

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

    Work Quality

    When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in 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 good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

    Cost

    This one is a give-and-take: similar to other 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 spectrum of price and financing options so they’re accessible to most homeowners.

    Warranty

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

    Years of Experience

    Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Clayton, MO Window Replacement FAQs

    How much does a window install cost?

    The national average cost of installing one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

    What are the different types of windows?

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

    What do window installers do?

    Window installation companies cover the entire process — from replacing your old windows with brand-new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.

    When is the best time of year to replace windows?

    Though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation more difficult.
