How Installing Energy-Efficient Windows in Charlton Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could help you:
- Better temperature control in your home: When you reside in a place like Charlton where the summers can get pretty warm, you often have to depend on your air conditioner to keep your house cool. Energy-efficient windows can cut back on the amount of cool air lost through your windows when cooling your home.
- 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.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Save money on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Charlton
Each window installer provides varying services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
According to our market research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. Costs will vary significantly depending on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step of an installation is to think about whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window without removing the complete frame, which is generally less expensive than a full-frame installation.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Charlton
The EcoWatch Reviews team is different from most reviewers since we evaluate these companies through a sustainability lens. We have reviewed the top window installation companies in Charlton mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Charlton so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, quality of installation, warranty, quality of parts, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that give you 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Charlton, MA Window Replacement FAQs
How much does a window install cost?
The typical cost to install one window can range between $450 and $650. There are several factors that influence the price, such as the materials used in designing the windows, the number of windows, how energy-efficient the windows are, your property's location, styles and sizes of windows and local labor costs.
What type of window is the most energy-efficient?
A window's energy efficiency is influenced by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Can you replace your own windows?
Even though you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you won't have to spend the time and effort to do it yourself.
Should I replace all my windows at once?
If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
