How Installing Energy-Efficient Windows in Spencer Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
- Save on electricity bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- More efficient energy use in your home: In Spencer where the summers can get pretty warm, energy-efficient windows decrease how much cool air is lost through your windows, which makes it easier to keep your home cool.
Estimated Cost of Window Replacement in Spencer
Windows come in varying purposes, shapes and styles, so costs and services will vary remarkably depending on your project. Below, we go over the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Even though the average to replace a single window is around $600, it can range from $200 to $1,200. How much it will cost is based on several factors, like material, the location of your home, number of windows, type, size and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
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 easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning an installation is to figure out whether you should get a full-frame or pocket installation.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the total window, including the trim, frame and sill. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
Your window installation company can advise you on the best type for your project. In Spencer, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Spencer
In our search to make your home improvements easier and more eco-friendly in Spencer, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Spencer, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Spencer.
Work Quality
When picking 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 choose. 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
Customer feedback is another very important review factor. If most customers don't have good feedback about their service from a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Spencer, MA Window Replacement FAQs
How much does a window install cost?
The typical cost of installing a window can range from $450 to $650. There are a variety of factors that influence how much it costs, such as styles and sizes of windows, the materials used in designing the windows, the number of windows, how energy-efficient the windows are, local labor costs and your property's location.
What are the kinds of windows?
There are several different types of windows you can get for your house, such as awning windows, bay windows, double-hung and single-hung windows, slider windows, transom windows, picture windows and casement windows.
What do window installation companies do?
Window installation professionals visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
