How Installing Energy-Efficient Windows in Leominster Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Save money on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
Estimated Cost of Window Replacement in Leominster
When researching window installation, each company provides different services and prices. Let’s look at some typical costs and services.
How Much Do New Windows Cost?
Even though the national average cost to replace a single window is about $600, it can range from $200 to $1,200. How much it will cost depends on several factors, including type, size, material, number of windows, the location of your home and more.
It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Leominster homeowners $482+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step of a replacement is to clarify whether you need a full-frame or pocket installation.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the old frame. So, instead of taking out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which kind of window installation service you should get, your installer can advise you. In general, the choice is influenced by 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 Leominster
In our search to make your home improvements easier and more eco-friendly in Leominster, EcoWatch landed on the above companies as the top window installation companies in the city. We have assessed the best window replacement companies in Leominster primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Leominster, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Leominster.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, cost, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Leominster’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Leominster window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
