Why you can trust EcoWatch
A review of the top window installation companies in Londonderry may not seem like the most captivating article on EcoWatch, but trust us, windows have more of an impact on your life than you might realize. Outdated windows can cost you in electric bills. As a matter of fact, the Department of Energy estimates that about 30% of your house's heat or cool air could be lost through your windows.
That's also bad news for the environment, as the additional energy used by old windows increases your carbon footprint.
Efficient windows are of particular importance in Londonderry, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $408 each year.

How Installing Energy-Efficient Windows in Londonderry Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, such as:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Save on energy bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $408 annually on your energy bills in Londonderry.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Londonderry, that's about 152 pounds per year on average.
Estimated Cost of Window Replacement in Londonderry
Windows come in all shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Though the typical of installing a single window is about $600, it can range from $200 to $1,200. But costs will vary significantly depending on the quality of your products, your location, the current condition of your home and the number of windows you need. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.
Whether or not you opt for 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 $408 a year on your energy bills in Londonderry.
Another factor that influences the overall cost is the material you pick for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of an installation is to think about whether you should get a full-frame or pocket installation.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are simpler and won't carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Londonderry
In our hunt to find the most reliable, eco-friendly window installers in Londonderry, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Londonderry, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Londonderry.
Work Quality
When picking new windows, the quality and range of services can often play just as important of a role in insulation 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
Customer feedback is another super important review factor. If most customers don't have good things to say 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 companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Londonderry, NH Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost of installing one window is about $600 but can range between $200 and $1,200, based on several factors. The price is typically dependent on 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 upfront but can save you a decent amount of money a year in energy bills.
What are the types of windows?
The most common kinds of windows for homes are slider windows, picture windows, transom windows, casement windows, bay windows, double-hung and single-hung windows and awning windows.
When should I use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a complex process that can take a lot of time, so it's best left to the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at once?
If you're upgrading your windows to save on your energy bills, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
