    How Installing Energy-Efficient Windows in Altoona Saves You Money

    Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to think about making the switch:

    • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
    • Save on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $305 annually on your energy bills in Altoona.
    • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Altoona, that’s about 286 pounds per year on average.
    • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.

    Estimated Cost of Window Replacement in Altoona

    Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs differ considerably based 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 will add extra costs to your project.

    Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $305 a year on your energy bills in Altoona.

    We recommend requesting free quotes from several window companies to find the right windows and the company 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 involve replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has considerable rot. These installations are more involved and will raise the overall cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

    If you’re still trying to decide which type of installation you should get, you can talk to your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage present.

    How We Choose the Best Window Installers in Altoona

    In our search to make your home improvements easier and more eco-friendly in Altoona, the EcoWatch team evaluated dozens of companies before landing on these. Along with energy efficiency, we assessed each installer 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 the Altoona area so you can find the best window installation company near you.

    Work Quality

    We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of installation, warranty, quality of parts and more.

    Cost

    Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

    Warranty

    As discussed, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

    Altoona, PA Window Replacement FAQs

    How much should window installation cost?

    The average cost of installing a window can range between $450 and $650. There are several factors that influence how much it costs, which include the materials used in designing the windows, styles and sizes of windows, your property’s location, how energy-efficient the windows are, local labor costs and the number of windows.

    What kind of window is the best for energy efficiency?

    A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

    Can you install your own windows?

    Even though you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

    Should I replace my windows all at the same time?

    If your windows are more than 20 years old, it’s probably time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.

    How long does window installation typically take?

    Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
