How Installing Energy-Efficient Windows in Derry Saves You Money
When you switch to energy-efficient windows, you may see a few perks, such as:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Save money on power bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save around $282 annually on your energy bills in Derry.
Estimated Cost of Window Replacement in Derry
When considering window installation, each company provides different services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. These figures vary depending on specific characteristics of your installation, including number of windows, material, the location of your home, type, size and more.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Getting free quotes from multiple companies is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first step when planning a window installation is to figure out whether you need a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Derry
EcoWatch reviews differ from most reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Derry, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Derry.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company included on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, cost, quality of parts, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Derry, PA Window Replacement FAQs
What is the typical cost to install new windows?
The average cost to install one window can range from $450 to $650. There are several factors that influence the price, which include the number of windows, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, local labor costs and your property's location.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you're getting 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 services do window installation companies provide?
Window installation companies cover the entire process — from replacing your old windows with new ones to cleaning up afterward. Additionally, many companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
