How Installing Energy-Efficient Windows in Leominster Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Protect your investment: If your home is on the older side, 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 property if you decide to sell.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Leominster, that's about 139 pounds per year on average.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient windows can help decrease that number, which helps you save some money on your bills.
Estimated Cost of Window Replacement in Leominster
Let's go over the cost of window installation and the types of services you may need for your home.
How Much Do New Windows Cost?
On average, Leominster homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost you depends on several factors, such as size, number of windows, material, type, the location of your home and more.
It's important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Leominster homeowners $482+ a year when replacing single-pane windows.
We advise requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your professionals will replace the full window, including the sill, trim and frame. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you choose what's best for your needs. In Leominster, the decision will mostly be based on how old your home is and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Leominster
In our search to find the most reliable, eco-friendly window installers in Leominster, the EcoWatch Reviews team assessed many companies before deciding on these. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Leominster area so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks 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 nice feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Leominster, MA Window Replacement FAQs
How much should window installation cost?
The national average cost to install one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
A window's energy efficiency depends on a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
When do I have to use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a complicated process that can take a lot of time, so it's best left to the professionals.
When is it time to replace your windows?
Windows generally have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them looked at by an expert to see if they are in need of a repair or replacement.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are usually 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.
