How Installing Energy-Efficient Windows in Centennial Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, such as:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date 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 fading of your furniture, carpet and other valuables.
- Save on energy bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $443 annually on your energy bills in Centennial.
Estimated Cost of Window Replacement in Centennial
Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
On average, homeowners in Centennial can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs will vary significantly based on the quality of your products, the current condition of your home, the number of windows you need and your location. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.
Whether or not you pick energy-efficient windows is another factor that will affect 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 Centennial.
We recommend requesting free quotes from several window installation companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your professionals will replace the total window, including the sill, trim and frame. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Centennial
In our hunt to make your home improvements easier and more eco-friendly in Centennial, the EcoWatch Reviews team assessed many companies before landing on these. Along with energy efficiency, we analyzed several window installers in Centennial and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Centennial so you can find the right window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide to ensure its contractors are well-qualified and that the company has received lots 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 might be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, warranty, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not 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
As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Centennial’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Centennial window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Centennial, CO Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the different kinds of windows?
There are several different kinds of windows you can get for your house, including bay windows, double-hung and single-hung windows, slider windows, casement windows, transom windows, picture windows and awning windows.
What do window installers do?
Window installers cover the entire process — from replacing your old windows with new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.
Should I replace all my windows at once?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
How long does window installation typically take?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
