How Installing Energy-Efficient Windows in Cromwell Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, such as:
- More efficient energy usage in your home: In Cromwell where the winters can be very cold, energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your home warm.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save $403 a year on your bills.
Estimated Cost of Window Replacement in Cromwell
Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Generally, homeowners in Cromwell can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. But prices vary remarkably based 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 will add extra costs to your project.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $403 a year on your energy bills in Cromwell.
Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
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.
Do I really need to use a window installation company?
Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
