How Installing Energy-Efficient Windows in Monroe Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: By using less energy after you switch to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Monroe
Windows come in different styles, shapes and purposes, so costs and services will differ tremendously depending on your project. Below, we describe the average cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
On average, homeowners in Monroe can anticipate that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. But prices differ remarkably 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 and replacements, which carry a higher price tag.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting free quotes from multiple installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies provide: full-frame and pocket installations.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Monroe
In our hunt to make your home improvements easier and more eco-friendly in Monroe, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Monroe, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Monroe.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Monroe, CT Window Replacement FAQs
How much should a window install cost?
The national average cost to install one window is about $600 but can range between $200 and $1,200, based on several factors. The price is typically influenced by the location of your property, the type and material of the window and the size 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.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installers visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it’s probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
How long does window installation generally take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
