Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's efficiency can also have a considerable impact on home energy conservation. Potential leaks or drafts can cut your home's energy efficiency by up to 30%, according to the Department of Energy. In Northampton, that's almost $475 per year that you could save on your electric bills by making the switch.
That's also bad for the environment, as the extra energy used by leaky windows increases your carbon footprint.
We've made a list of the best installation companies to help you in your search, so you can not only enjoy brand new windows, but also save money on your electricity bills.

How Installing Energy-Efficient Windows in Northampton Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Northampton
Each window installation company provides various services and has different costs depending on several factors.
How Much Do New Windows Cost?
Generally, homeowners in Northampton can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. These figures are based on the specifics of your installation, like the location of your home, number of windows, material, type, size and more.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $475 a year on your energy bills in Northampton.
Something else that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window without removing the entire frame, which is usually cheaper than a full-frame installation.
Your window replacement company will be able to help you understand what's best for your needs. In Northampton, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Northampton
EcoWatch reviews differ from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Northampton area so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. 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 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: similar to most services, cheap window installation companies are not going to provide the most quality service. Still, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a hefty 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.
Do I really have to use a window installation company?
You should use a window installation company whenever you want to upgrade your windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.
How long does window installation typically take?
Because a window takes about 30 minutes to install, around 16 windows can be installed during a typical 8-hour work day.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
