How Installing Energy-Efficient Windows in Greeley Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Decrease your carbon footprint: In Greeley, you can cut your indirect greenhouse gas emissions by about 460 pounds per year when you install energy-efficient windows.
- Save money on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save around $457 annually on your energy bills in Greeley.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Greeley
Each window installation company offers various services and has different prices based on a few factors.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range from $200 to $1,200. Costs will differ considerably based on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Greeley homeowners $457+ a year when replacing single-pane windows.
We recommend requesting free quotes from several window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In Greeley, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Greeley
In our hunt to find the most reliable, eco-friendly window installers in Greeley, EcoWatch examined many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Greeley and ranked them using the following methodology:
Service Area
Because this is a guide for Greeley, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Greeley.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, cost, warranty, professionalism, quality of parts and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. On the other hand, we want to ensure 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 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
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Greeley, CO Window Replacement FAQs
What is the average cost to replace windows in a home?
The typical cost of installing a single window can range between $450 and $650. There are a variety of factors that influence how much it costs, such as styles and sizes of windows, local labor costs, your property's location, the number of windows, the materials used in designing the windows and how energy-efficient the windows are.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.
How long does window installation usually take?
Since the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
