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.

Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home’s efficiency can also have a big impact on home energy conservation. If your windows are made of traditional materials, or are outdated or damaged, you could be sending 25-30% of your home’s heat or cool air right out of them.

That’s also bad news for the environment, as the additional energy used by leaky windows increases your carbon footprint.

As windows are so important for your home, choosing the right company for you is a big decision to make. That’s why the EcoWatch team has created this list of the best window installation companies, so you can more easily make an informed decision.

    How Installing Energy-Efficient Windows in St. Louis Saves You Money

    Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

    • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 763 pounds per year on average.
    • Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
    • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.

    Estimated Cost of Window Replacement in St. Louis

    When researching window installation, each company provides different services and prices. Let’s go over some average costs and services.

    How Much Do New Windows Cost?

    According to our research, the typical cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. But costs vary 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 provide door installations, which carry a higher price tag.

    Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $374 a year on your energy bills in St. Louis.

    Getting free quotes from multiple installers is the best way to figure out which one is right for you.

    What Services do Window Installers Offer?

    Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

    Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the total window, including the trim, sill and frame. A pocket installation involves installing a new window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

    If you’re still trying to decide which kind of installation you need, you can ask your installer and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage present.

    How We Choose the Best Window Installers in St. Louis

    EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in St. Louis and ranked them using the following methodology:

    Service Area

    Because this is a guide for St. Louis, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in St. Louis.

    Work Quality

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

    Customer Reviews

    Customer feedback is another very important review factor. If most customers don’t have nice feedback about their service from a certain company, you won’t see it featured on EcoWatch.

    Cost

    This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. On the other hand, 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 substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    St. Louis, MO Window Replacement FAQs

    What is the typical cost to replace windows in a home?

    The national average cost to replace a 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 type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

    What are the types of windows?

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

    What services do window installation companies do?

    Window installation professionals visit your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.

    What time of year is a good time to replace my windows?

    Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
