How Installing Energy-Efficient Windows in Northampton Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:
- Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- More efficient energy use in your household: In Northampton where the winters can get cold, energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your house warm.
Estimated Cost of Window Replacement in Northampton
Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the typical cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will make your project cost more.
It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Northampton homeowners $475+ a year when replacing single-pane windows.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Northampton
EcoWatch reviews differ from other reviews, as we're examining these companies through a sustainability lens. We've reviewed the best window installers in Northampton primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand 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
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice feedback about their service from 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 installers may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Northampton's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Northampton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Northampton, MA Window Replacement FAQs
How much should a window install cost?
The average cost to replace one window ranges between $450 and $650. There are a variety of factors that affect the cost, including styles and sizes of windows, the number of windows, your property's location, the materials used in designing the windows, how energy-efficient the windows are and local labor costs.
What are the types of windows?
The most common kinds of windows for homes are transom windows, bay windows, casement windows, picture windows, awning windows, slider 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 requires a lot of time and experience with home improvement projects. Using a window installation company can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
