How Installing Energy-Efficient Windows in Littleton Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to make the switch:
- Better temperature control in your home: When you reside in a city like Littleton where the winters can get very cold, you usually have to depend on your heater to keep your house warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat your home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help lower that amount, which helps you save $464 a year on your bills.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged.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 Littleton
Windows come in different purposes, styles and shapes, so costs and services will vary considerably depending on your project. Below, we go over the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
According to our research, the typical cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. These figures are based on the specifics of your installation, such as material, size, number of windows, type, the location of your home and more.
Whether or not you choose 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 $464 a year on your energy bills in Littleton.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a replacement is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the full window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation entails replacing a window within the old frame. So, instead of tearing out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Littleton
The EcoWatch Reviews team is different from most reviewers since we assess these companies through a sustainability lens. We've reviewed the best window installation companies in Littleton mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your 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 Littleton, we gave more points to companies that serve the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Littleton.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to be certain that investment is well protected. 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.
Littleton, MA Window Replacement FAQs
What is the average cost to install new windows?
The typical cost to install a single window can range from $450 to $650. There are many factors that influence how much it costs, including styles and sizes of windows, your property's location, the materials used in designing the windows, how energy-efficient the windows are, local labor costs and the number of windows.
What are the types of windows?
There are various kinds of windows you can get for your home, including awning windows, slider windows, casement windows, bay windows, picture windows, transom windows and double-hung and single-hung windows.
Can you replace your own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, it shouldn't be raining, as rain can make the installation harder.
