How Installing Energy-Efficient Windows in Westford Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Save money on electricity bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Westford, that's about 139 pounds per year on average.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Westford
Windows come in different styles, shapes and purposes, so costs and services will differ tremendously depending on your project. Below, we describe the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
According to our research, the typical cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will make your project cost more.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $418 a year on your energy bills in Westford.
Something else that affects the total cost is the material of the frame you choose. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which type of installation you should get, you can talk to your provider and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Westford
In our hunt to find the most reliable, eco-friendly window installers in Westford, the EcoWatch Reviews team examined dozens of companies before landing on these. We have decided to review the top window replacement companies in Westford mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your electricity 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 the Westford area so you can find the best window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest 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
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Westford, MA Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost of installing one window can range from $450 to $650. There are several factors that affect the price, such as the number of windows, local labor costs, your property's location, styles and sizes of windows, how energy-efficient the windows are 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 are slider windows, casement windows, bay windows, awning windows, picture windows, transom windows and double-hung and single-hung windows.
What services do window replacement companies provide?
Window installation professionals visit your house to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How long does it generally take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
Should I replace all my windows at once?
If you're upgrading your windows to get more efficient windows, replacing all your windows at the same time 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.
