How Installing Energy-Efficient Windows in Aspen Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- 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- Protect your investment: When you have an older home, your windows could also be outdated or drafty.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 from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Aspen
Each window installer offers varying services and has varying costs based on several factors.
How Much Do New Windows Cost?
Although the national average of installing one window is about $600, it can range from $200 to $1,200. These amounts vary based on specific characteristics of your installation, such as size, type, the location of your home, material, number of windows and more.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $668 a year on your energy bills in Aspen.
Asking for free quotes from several installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first step of a window installation is to decide whether you want a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without replacing the frame. So, instead of taking out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Aspen, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Aspen
In our search to make your home improvements easier and more eco-friendly in Aspen, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We've reviewed the best window installation companies in Aspen primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Aspen, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Aspen.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction might 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: similar to most services, cheap window companies won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide 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 provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Aspen, CO Window Replacement FAQs
What is the average cost to install windows in a home?
The average cost to install a single window can range from $450 to $650. There are several factors that influence the price, including the materials used in designing the windows, local labor costs, how energy-efficient the windows are, the number of windows, your property's location and styles and sizes of windows.
What are the different types of windows?
The most common kinds of windows for homes are awning windows, slider windows, transom windows, double-hung and single-hung windows, bay windows, picture windows and casement windows.
Do I really need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at the same time?
If you're upgrading your windows to get more efficient windows, replacing all of the windows at the same time is the only way to gain that benefit. However, if you have just one or two windows that are broken or drafty, you can replace just those.
