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.

Whether you're updating for aesthetics or have windows that need repairs, windows play a crucial role in conserving energy in your home. Potential leaks or drafts from your windows can make your AC or heater work extra hard in the summer or winter.

That’s also bad news for the environment because the extra energy used by old windows increases your carbon footprint.

Efficient windows are particularly important in Fairmount, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $443 each year.

How Installing Energy-Efficient Windows in Fairmount Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:

  • 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.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save $443 a year on your bills.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Fairmount

Each window installation company provides various services and has different prices depending on several factors.

How Much Do New Windows Cost?

Typically, Fairmount homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost varies based on several factors, like the location of your home, size, material, number of windows, type and more.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $443 a year on your energy bills in Fairmount.

We advise requesting free quotes from several window installers to find the one that works best for you.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, 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 understand what’s best for your needs. In Fairmount, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Fairmount

EcoWatch differs from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

Service Area

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

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer in our guide to make sure its contractors 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 online reviews 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 reflects the quality of services across nearly every category, including quality of parts, warranty, quality of installation, professionalism, cost and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like 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 provide lengthy warranties for products, parts and labor 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 installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Fairmount, CO Window Replacement FAQs

What is the typical cost to replace windows?

The national average cost to install a window is about $600 but can range from $200 to $1,200, based on a few different 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, 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 should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.

Should I replace my windows all at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all of your windows at once is the only way to gain that benefit. However, if you have just one or two windows that are broken or leaky, you can replace just those.
