The Department of Energy estimates that heat or cool air lost through old or damaged windows could make up about 30% of heating and cooling usage.

How Installing Energy-Efficient Windows in Londonderry Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Reduce your carbon footprint: In Londonderry, you can cut your indirect greenhouse gas emissions by about 152 pounds per year after you upgrade to energy-efficient windows.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save $435 a year on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Londonderry
Windows come in different styles, shapes and purposes, so costs and services will differ remarkably depending on your project. Below, we detail the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, Londonderry homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost you varies depending on several factors, including material, size, the location of your home, number of windows, type and more.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Londonderry homeowners $435+ a year after replacing single-pane windows.
Another factor that affects the total cost is the material you choose 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?
There are typically two types of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In Londonderry, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Londonderry
EcoWatch is different from other reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Londonderry and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Londonderry so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of parts, warranty, professionalism, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Londonderry's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Londonderry window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Londonderry, NH Window Replacement FAQs
What is the typical cost to install windows in a home?
The typical cost to replace a window can range from $450 to $650. There are a variety of factors that influence the price, which include the materials used in designing the windows, the number of windows, your property's location, local labor costs, how energy-efficient the windows are and styles and sizes of windows.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: slider windows, double-hung and single-hung windows, casement windows, picture windows, bay windows, awning windows and transom windows.
When do I need to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. 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 house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
