How Installing Energy-Efficient Windows in Fort Collins Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to take the plunge and make 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 fade less because of their ability to filter out harmful UV rays.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save on electricity bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your house.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 460 pounds.
Estimated Cost of Window Replacement in Fort Collins
Each window installation company offers various services and has varying costs depending on a few factors.
How Much Do New Windows Cost?
Although the average cost to replace a single window is around $600, it can range 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 replacements, which will make your project cost more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
We recommend requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies provide: 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 professionals will replace the full window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame. So, instead of removing the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which window installation service you need, your installer can advise you. In general, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Fort Collins
The EcoWatch Reviews team differs from most reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Fort Collins and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Fort Collins, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Fort Collins.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great 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 tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers won’t always 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 to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Fort Collins’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Fort Collins window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Fort Collins, CO Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost of replacing a single window can range from $450 to $650. There are several factors that influence how much it costs, which include the materials used in designing the windows, your property’s location, local labor costs, how energy-efficient the windows are, the number of windows and styles and sizes of windows.
What kind of window is the best for energy efficiency?
A window’s energy efficiency is influenced by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
When should I use a window installation company?
Unless you’re handy and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter 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.
Should I replace all my windows at once?
If you’re upgrading your windows because of energy-efficiency, replacing all your windows at the same time is the only way to see a noticeable difference. However, if you have just a few windows that are broken or drafty, you can replace just those.
