Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home’s energy efficiency can also have a large impact on home energy conservation. Outdated windows can cost you in power bills. In fact, the Department of Energy estimates that 25-30% of your home’s heat or cool air could be lost through your windows.
That’s also bad news for the environment, as the additional energy used by old windows increases your carbon footprint.
Efficient windows are particularly important in Charlton, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $482 a year.

How Installing Energy-Efficient Windows in Charlton Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could benefit you:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
- Reduce your carbon footprint: In Charlton, you can lower your indirect greenhouse gas emissions by about 139 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Charlton
Let’s take a look at the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Typically, Charlton homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost depends on several factors, including type, number of windows, the location of your home, size, material and more.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $482 a year on your energy bills in Charlton.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first step when considering a window installation is to decide whether you need a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the whole window, including the trim, sill and frame. A pocket installation means replacing a window without taking out the entire frame, which is generally cheaper than a full-frame installation.
If you’re unsure which window installation service you need, your installer should be able to help you out. In general, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Charlton
EcoWatch differs from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
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 a quality window installation company near you.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you opt for. 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Charlton’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Charlton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Charlton, MA Window Replacement FAQs
How much does window installation cost?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
When do I 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 the pros. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.
Should I replace my windows all at once?
If you’re upgrading your windows to save on your energy bills, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
