How Installing Energy-Efficient Windows in West Haven Saves You Money
There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Save money on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Better temperature control in your home: When you live in a city like West Haven where the winters can be very cold, you often need to rely on your heater to keep your house warm. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in West Haven
When researching window installation, each company provides different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, like material, size, the location of your home, type, number of windows and more.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
We advise getting free quotes from several window installation companies to find the one that works best for you.
What Services do Window Installers Offer?
The first step of a window installation is to clarify whether you should get a full-frame or pocket installation.
A full-frame installation is a replacement of the full window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which raise the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window without taking out the complete frame, which is generally cheaper than a full-frame installation.
Your window installation company will be able to recommend the best type for your project. In West Haven, the choice will mostly be based on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in West Haven
The EcoWatch Reviews team differs from most reviewers because we're examining these companies through a sustainability lens. We've reviewed the best window installers in West Haven mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve West Haven so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of West Haven's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of West Haven window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
West Haven, CT Window Replacement FAQs
How much does window installation cost?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is typically 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 upfront but can save you hundreds of dollars a year in energy bills.
What are the kinds of windows?
There are several different kinds of windows you can get for your home, such as awning windows, transom windows, slider windows, casement windows, picture windows, bay windows and double-hung and single-hung windows.
What do window installers do?
Window installers visit your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are broken or drafty, you can replace just those.
