Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's efficiency can also have a big impact on home energy conservation. If your windows are made of traditional materials, or are outdated or damaged, you could be sending 25-30% of your home's heat or cool air out of them.
Fortunately, saving you energy with more efficient windows also helps our goals of reducing energy usage for the environment.
So if you're building a new home, renovating or changing out old windows in Millis, you've found the best place to get started.

How Installing Energy-Efficient Windows in Millis Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Installing energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing 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- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Millis
When looking into window installation, each company provides different services and prices. Let's look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which carry a higher price tag.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Millis homeowners $454+ a year after replacing single-pane windows.
We advise getting free quotes from several window installation companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket 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 kind of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Millis
In our search to make your home improvements easier and more eco-friendly in Millis, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Millis so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Millis' climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Millis window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Millis, MA Window Replacement FAQs
How much should a window install cost?
The typical cost of replacing a window can range between $450 and $650. There are several factors that influence the cost, which include how energy-efficient the windows are, styles and sizes of windows, the number of windows, the materials used in designing the windows, your property's location and local labor costs.
Which kind of window is the best?
A window's energy efficiency depends on a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window installation companies provide?
Window installers will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.
How long does it typically take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
When is it time 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 any damage on them, or they have become difficult to operate, they may be in need of replacement.
