Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's efficiency can also have a considerable impact on home energy conservation. During the winter months, the last thing you want is your heat to leak out of your outdated, drafty windows.
That's also bad news for the environment because the extra energy used by outdated windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window replacement companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Windsor Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 460 pounds per year on average.
- Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
Estimated Cost of Window Replacement in Windsor
When considering window installation, each company provides different services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. These estimates are based on specific characteristics of your installation, like material, the location of your home, type, size, number of windows and more.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $372 a year on your energy bills in Windsor.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first question 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 complete window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
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 Windsor
In our hunt to make your home improvements easier and more eco-friendly in Windsor, the EcoWatch Reviews team evaluated many companies before deciding on these. We've reviewed the best window replacement companies in Windsor mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Windsor, we only included companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Windsor.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, cost, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest 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
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
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Windsor, CO Window Replacement FAQs
What is the average cost to install windows?
The typical cost of installing one window ranges from $450 to $650. There are a variety of factors that affect how much it costs, such as your property's location, the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows, the number of windows and local labor costs.
What kind of window is the best for energy efficiency?
A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a complicated process that can take a lot of time, so it's best handled by the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
