How Installing Energy-Efficient Windows in Mansfield Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, 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 raise the value of your property if you decide to sell.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Mansfield
Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.
It's important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Mansfield homeowners $437+ a year when replacing single-pane windows.
We advise getting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
The first step when planning an installation is to clarify whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves installing a new window within the existing frame. So, instead of tearing out the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to help you choose what's best for your needs. In Mansfield, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Mansfield
In our hunt to make your home improvements easier and more eco-friendly in Mansfield, EcoWatch assessed dozens of companies before settling on these. We have assessed the best window replacement companies in Mansfield mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of installation, cost, quality of parts, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when 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 substantial investment, so you'll want to be certain that investment is well protected. Window installation companies with 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 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.
Mansfield, CT Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What kind of window is the most energy-efficient?
A window's energy efficiency depends on several factors, such as 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 need to use a window installation company?
You should hire a window installation company whenever you want new windows. Installing windows is a complicated process that can take a lot of time, so it's best handled by the professionals.
When is it time to replace your windows?
Windows typically last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
Should I replace my windows all at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
