Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a big impact on home energy conservation. If your windows are drafty or damaged, you could be losing 25-30% of your house's heat or cool air right out of them.
That's also bad news for the environment, as the extra energy used by old windows increases your carbon footprint.
So if you're building a new home, renovating or updating your windows in Denver, this is the best place to get started.

How Installing Energy-Efficient Windows in Denver Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 286 pounds per year on average.
Estimated Cost of Window Replacement in Denver
When looking into window installation, each company provides different services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Though the typical to install a single window is about $600, it can range anywhere from $200 to $1,200. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Requesting free quotes from multiple installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the entire window, including the trim, sill and frame. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're still debating which type of installation to get, you can ask your provider and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Denver
In our search to find the most reliable, eco-friendly window installers in Denver, EcoWatch landed on the above companies as the top window installation companies in the city. We've reviewed the best window installation companies in Denver primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When installing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have positive things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Denver's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Denver window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Denver, PA Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost to install a single window can range between $450 and $650. There are several factors that influence how much it costs, which include how energy-efficient the windows are, styles and sizes of windows, local labor costs, the number of windows, the materials used in designing the windows and your property's location.
What are the different kinds of windows?
There are various kinds of windows you can get for your house, such as bay windows, transom windows, slider windows, awning windows, casement windows, picture windows and double-hung and single-hung windows.
What services do window installation companies do?
Window installation professionals go to your property to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn't be raining, because rain can make the installation more difficult.
How often do you need to replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
