Why you can trust EcoWatch
Whether you're updating for aesthetics or have damaged windows, windows play a vital role in conserving energy in your home. During the winter months, the last thing you want is your heat to leak out of your outdated windows.
That's also bad for the environment because the additional energy required by leaky windows increases your carbon footprint.
Efficient windows are of particular importance in New London, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $304 a year.

How Installing Energy-Efficient Windows in New London Saves You Money
When you switch to energy-efficient windows, you may see a few perks, such as:
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in New London
Windows come in varying purposes, shapes and styles, so costs and services will vary greatly depending on several factors. Below, we describe the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the typical cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But costs differ 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 offer door installations, which have a higher price tag.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $304 a year on your energy bills in New London.
Costs will also vary depending on the material you want for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from 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?
The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you figure out what's best for your needs. In New London, the decision will mostly depend on the age of your home and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in New London
The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in New London and assigned rankings using the following methodology:
Service Area
Because this is a guide for New London, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in New London.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, professionalism, cost, warranty, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that offer 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 installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
New London, PA Window Replacement FAQs
How much does a window install cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on several factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installers go to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How often do you need to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
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 the windows together is the only way to see a noticeable difference. However, if you have only one or two windows that are broken or drafty, you can replace just those.
