How Installing Energy-Efficient Windows in Pittsfield Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could benefit you:
- Save on energy bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 139 pounds per year on average.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Pittsfield
When considering window installation, each company provides different services and prices. Let’s go over some average costs and services.
How Much Do New Windows Cost?
On average, homeowners in Pittsfield can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. This is because window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $524 a year on your energy bills in Pittsfield.
Requesting free quotes from multiple providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: 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 while leaving the existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re not sure which kind of window installation service you should get, your installer should be able to assist you. Generally, the choice depends 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 Pittsfield
The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. We have decided to evaluate the top window replacement companies in Pittsfield primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Pittsfield so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you get. 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
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, cost, quality of installation, professionalism, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a variety 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 offer lengthy warranties for products, parts and labor 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Pittsfield, MA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The average cost to install one window ranges from $450 to $650. There are many factors that affect the price, such as styles and sizes of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are, your property’s location and the number of windows.
Which kind of window should I get?
A window’s energy efficiency is influenced by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installers do?
Window installers go to your home 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 is complete.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows at once is the only way to gain that benefit. On the other hand, if you have just a few windows that are damaged or drafty, you can replace just those.
