How Installing Energy-Efficient Windows in East Hampton Saves You Money
When you switch to energy-efficient windows, you may see some benefits, including:
- Decrease your carbon footprint: In East Hampton, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you switch to energy-efficient windows.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in East Hampton
Each window replacement company provides various services and has varying prices based on a few factors.
How Much Do New Windows Cost?
Even though the typical cost of replacing a single window is around $600, it can range anywhere from $200 to $1,200. But costs 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 replacements, which will make your project cost more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save East Hampton homeowners $403+ per year after replacing single-pane windows.
We recommend getting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first step when considering a window installation is to think about whether you want a full-frame or pocket installation.
A full-frame installation replaces the complete 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 likely need a full-frame installation instead.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in East Hampton
In our hunt to find the most reliable, eco-friendly window installers in East Hampton, the EcoWatch Reviews team examined many companies before settling on these. We have decided to evaluate the best window installers in East Hampton primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve East Hampton so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide to ensure its technicians are well-qualified and that the company has gotten 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 positive things to say about their service from a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a variety 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 be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
East Hampton, CT Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a window ranges between $450 and $650. There are several factors that influence how much it costs, including styles and sizes of windows, your property’s location, how energy-efficient the windows are, the materials used in designing the windows, local labor costs and the number of windows.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your home, such as slider windows, awning windows, picture windows, casement windows, bay windows, double-hung and single-hung windows and transom windows.
When do I have to use a window installation company?
You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a involved process that can take a lot of time, so it’s best left to the professionals.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows at once is the only way to see a noticeable difference. However, if you have just one or two windows that are broken or drafty, you can replace just those.
How long does window installation take?
Each window takes around 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 have to be installed.
