How Installing Energy-Efficient Windows in Firestone Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Better temperature control in your home: Residing in a hot place like Firestone usually means needing your AC to keep your house cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
- Save money on electricity bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Firestone
When considering window installation, each company provides varying services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Firestone can expect that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. These estimates are based on the specifics of your installation, such as type, number of windows, material, size, the location of your home and more.
It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Firestone home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Firestone
EcoWatch differs from other reviewers because we assess these companies through a sustainability lens. We've reviewed the top window installers in Firestone mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Firestone, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Firestone.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) 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 installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Firestone, CO Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost of replacing one window ranges between $450 and $650. There are many factors that influence how much it costs, which include the number of windows, local labor costs, the materials used in designing the windows, styles and sizes of windows, your property's location and how energy-efficient the windows are.
What are the kinds of windows?
The most common kinds of windows for homes include: picture windows, bay windows, casement windows, slider windows, awning windows, double-hung and single-hung windows and transom windows.
Can I install my own windows?
If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or know-how, we don't recommend trying it.
Should I replace my windows all at once?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
