How Installing Energy-Efficient Windows in Littleton Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Littleton
Windows come in different styles, shapes and purposes, so costs and services will vary remarkably based on your project. Below, we detail the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
On average, homeowners in Littleton can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost depends on several factors, including number of windows, size, type, the location of your home, material and more.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Littleton homeowners $443+ a year after replacing single-pane windows.
Getting free quotes from multiple providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first step when considering an installation is to think about 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 type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you choose what’s best for your needs. In Littleton, the decision will mostly be based on the age of your home and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Littleton
In our hunt to find the most reliable, eco-friendly window installers in Littleton, the EcoWatch team chose the above companies as the best window installation companies in the city. We have evaluated the best window installers in Littleton primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power 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 Littleton so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Littleton, CO Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost to replace a window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
A window’s energy efficiency is affected by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Can I replace my own windows?
Although it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.
When is the best time of year to replace 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 ensure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
