How Installing Energy-Efficient Windows in Cromwell Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Reduce your carbon footprint: By using less energy once you switch to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on energy bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save about $403 annually on your energy bills in Cromwell.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Cromwell
Each window installation company provides various services and has different prices based on a few factors.
How Much Do New Windows Cost?
Although the national average of installing one window is about $600, it can range anywhere from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
When it comes to window replacements, there are generally two types that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. A pocket installation means replacing a window without removing the complete frame, which is generally cheaper than a full-frame installation.
Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Cromwell
EcoWatch reviews differ from most reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Cromwell, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Cromwell.
Work Quality
When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. 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 positive things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Cromwell's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Cromwell window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Cromwell, CT Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to replace one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window's energy efficiency is influenced by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation companies cover the entire process — from replacing old windows with new ones to cleaning up afterward. Additionally, a lot of companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
How do you know it's time to replace your windows?
Windows generally 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 determine if they are in need of a repair or replacement.
