How Installing Energy-Efficient Windows in Littleton Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to make the switch:
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Save on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Littleton
Let’s take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
On average, Littleton homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. These amounts vary depending on the specifics of your installation, like the location of your home, type, material, size, number of windows and more.
It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Littleton homeowners $464+ a year when replacing single-pane windows.
We recommend requesting free quotes from multiple window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the total window, including the frame, sill and trim. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Littleton
In our hunt to make your home improvements easier and more eco-friendly in Littleton, the EcoWatch team assessed dozens of companies before deciding on these. Along with energy efficiency, we assessed several window installers in Littleton and ranked them using the following methodology:
Service Area
Because this is a guide for Littleton, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Littleton.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure 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 to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Littleton’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Littleton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Littleton, MA Window Replacement FAQs
How much should window installation cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes are bay windows, picture windows, double-hung and single-hung windows, transom windows, slider windows, awning windows and casement windows.
Do you really need to use a window installation company?
You should use a window installation professional whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult to do on your own, so it’s best left to the professionals.
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. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all your windows at once is the only way to gain that benefit. However, if you have only one or two windows that are broken or leaky, you can replace just those.
