How Installing Energy-Efficient Windows in Northampton Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, including:
- Decrease your carbon footprint: In Northampton, you can reduce your indirect greenhouse gas emissions by about 286 pounds per year after you upgrade to energy-efficient windows.
- More efficient energy usage in your home: Because the summers can get quite hot in Northampton, homeowners often rely on their air conditioner during that time. Energy-efficient windows cut back on the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
Estimated Cost of Window Replacement in Northampton
Windows come in different purposes, styles and shapes, so costs and services will differ greatly depending on several factors. Below, we detail the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, including size, type, number of windows, material, the location of your home and more.
It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Northampton home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We advise 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?
The first step when considering an installation is to decide whether you should get a full-frame or pocket installation.
Full-frame installations entail replacing the total window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Because full-frame installations are more involved, they will increase the total cost. Pocket installations are on the simpler end and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
If you're unsure which kind of window installation service you should get, your installer can help you out. Typically, the choice is based on 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 Northampton
EcoWatch differs from most reviewers, as we evaluate these companies through a sustainability lens. We have evaluated the best window replacement companies in Northampton mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower 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 installers that serve the Northampton area so you can find the best window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you get. 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 trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, professionalism, warranty, cost, quality of parts and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Northampton, PA Window Replacement FAQs
What is the typical cost to install windows?
The typical cost to install one window can range between $450 and $650. There are a variety of factors that affect the price, which include the number of windows, styles and sizes of windows, how energy-efficient the windows are, local labor costs, your property's location and the materials used in designing the windows.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: bay windows, slider windows, awning windows, picture windows, transom windows, double-hung and single-hung windows and casement windows.
What do window installers do?
Window installation professionals go to your house to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
