How Installing Energy-Efficient Windows in Millis Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Save money on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $454 annually on your energy bills in Millis.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- More efficient energy use in your home: In Millis where the winters can be very cold, energy-efficient windows cut back on the amount of heat that is lost through your windows, which makes it easier to keep your house warm.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Millis
Windows come in different shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you'll find from the average window installation company.
How Much Do New Windows Cost?
According to our research, the typical cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because the cost of window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Millis homeowners $454+ a year after replacing single-pane windows.
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?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you decide what's best for your needs. In Millis, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if not maintained properly 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 Millis
EcoWatch differs from other reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Millis and assigned rankings using the following methodology:
Service Area
Since this is a guide for Millis, we gave more points to companies that cover the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Millis.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, cost, warranty, quality of parts and more.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the highest 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 previously, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers 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.
Millis, MA Window Replacement FAQs
What is the average cost to replace windows in a home?
The average cost of installing a window ranges from $450 to $650. There are a variety of factors that influence the cost, such as your property's location, the materials used in designing the windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are and the number of windows.
What are the different types of windows?
The most common kinds of windows for homes are transom windows, slider windows, picture windows, double-hung and single-hung windows, awning windows, bay windows and casement windows.
What do window installers do?
Window installers will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
