How Installing Energy-Efficient Windows in Greeley Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $457 annually on your energy bills in Greeley.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Greeley, that’s about 460 pounds per year on average.
Estimated Cost of Window Replacement in Greeley
Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
On average, Greeley homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. But prices 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.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from multiple installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two types that your provider will have: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re not sure which type of window installation service you need, your installer should be able to help you out. In general, the decision 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 Greeley
In our search to make your home improvements easier and more eco-friendly in Greeley, the EcoWatch Reviews team evaluated dozens of companies before deciding on these. 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 Greeley, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Greeley.
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 in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have good things to say about their service from 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 installation companies are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Greeley, CO Window Replacement FAQs
What is the typical cost to replace windows?
The average cost to install one window ranges between $450 and $650. There are several factors that affect how much it costs, such as the number of windows, how energy-efficient the windows are, styles and sizes of windows, your property’s location, the materials used in designing the windows and local labor costs.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll have 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.
What services do window installation companies do?
Window installation professionals cover the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.
How long does it usually take to install windows?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
