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.

Keystone, FL Window Replacement FAQs

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

The average cost to install one window ranges from $450 to $650. There are a variety of factors that influence how much it costs, which include the number of windows, local labor costs, how energy-efficient the windows are, your property’s location, styles and sizes of windows and the materials used in designing the windows.

What are the most common types of replacement windows?

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

What services do window replacement companies do?

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

How often should you replace your windows?

Windows typically last around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them looked at by an expert to determine if they need any repairs or replacements.
