    How Installing Energy-Efficient Windows in Tomball Saves You Money

    There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

    • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
    • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
    • Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 465 pounds per year on average.
    • Save on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.

    Estimated Cost of Window Replacement in Tomball

    Windows come in varying purposes, shapes and styles, so costs and services will vary tremendously based on several factors. Below, we detail the typical cost and services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, such as material, number of windows, the location of your home, type, size and more.

    Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

    We recommend getting free quotes from several window companies to find the one that works best for your budget.

    What Services do Window Installers Offer?

    In regard to window replacements, there are generally two types that your provider will have: 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 a lot of deterioration. With this service, your installers will replace the full window, including the trim, sill and frame. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

    Your window replacement company should be able to help you understand what’s best for your needs. In Tomball, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.

    How We Choose the Best Window Installers in Tomball

    In our search to make your home improvements easier and more eco-friendly in Tomball, the EcoWatch Reviews team examined dozens of companies before landing on these. We’ve assessed the best window replacement companies in Tomball mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

    Service Area

    This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Tomball so you can find the best 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 installer included on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

    Customer Reviews

    Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have nice things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.

    Cost

    This one is a give-and-take: similar to most services, cheap window companies are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

    Warranty

    Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) 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 experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

    Tomball, TX Window Replacement FAQs

    What is the average cost to install new windows in a home?

    The national average cost to replace a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

    Which type of window is the best?

    Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

    Can I install my own windows?

    If you’re handy and have experience with installing a replacement window, it’s possible to install your own windows. However, if you don’t have the time or experience, we recommend getting a professional to do it for you.

    When is the best time of year to replace windows?

    Replacement windows can be installed any time of the year, but autumn might be the best season. 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 doesn’t necessarily matter that much. Most importantly, the weather should be dry.

    How often do you need to replace 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. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
