How Installing Energy-Efficient Windows in Keystone Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $415 a year on your bills.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Keystone, that’s about 349 pounds per year on average.
- 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.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Keystone
Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
Typically, Keystone homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at about $600. But costs will vary considerably based on the quality of your products, the current condition of your home, the number of windows you need and your location. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Keystone homeowners $415+ each year after replacing single-pane windows.
Asking for free quotes from several installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
In regard to window installations, in general there are two kinds that your provider will offer: 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 professionals will replace the complete window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company will be able to help you figure out what’s best for your needs. In Keystone, the decision will mostly depend 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 good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Keystone
In our hunt to make your home improvements easier and more eco-friendly in Keystone, the EcoWatch Reviews team assessed many companies before settling on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Keystone, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Keystone.
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 on this list to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of installation, cost, quality of parts and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Keystone’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Keystone window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
