How Installing Energy-Efficient Windows in Greenwood Village Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:
- Save money on energy bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save around $443 annually on your energy bills in Greenwood Village.
- 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.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Greenwood Village
Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the average costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
Generally, Greenwood Village homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at approximately $600. But costs vary remarkably 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 add extra costs to your project.
It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Greenwood Village homeowners $443+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
When considering window replacements, in general there are two kinds that your installer will offer: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has considerable rot. These installations are more involved and will raise overall costs. A pocket installation means replacing a window without taking out the whole frame, which is usually cheaper than a full-frame installation.
Your window installation company will be able to help you understand what’s best for your needs. In Greenwood Village, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Greenwood Village
EcoWatch differs from most reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Greenwood Village area so you can find a quality window installation company near you.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company 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
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, professionalism, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a spectrum 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Greenwood Village, CO Window Replacement FAQs
How much should window installation cost?
The average cost to install one window ranges between $450 and $650. There are several factors that influence the cost, such as the materials used in designing the windows, the number of windows, how energy-efficient the windows are, your property’s location, local labor costs and styles and sizes of windows.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies provide?
Window installation professionals cover the entire process — from replacing your old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.
What time of year is a good time to replace my windows?
Though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
