How Installing Energy-Efficient Windows in Derry Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 152 pounds per year on average.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient windows can help reduce that amount, which helps you save more on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Derry
Windows come in different styles, shapes and purposes, so costs and services will vary remarkably based on your project. Below, we describe the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, Derry homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Derry homeowners $435+ per year after replacing single-pane windows.
Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are simpler and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company will be able to recommend the best type for your project. In Derry, the choice will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Derry
In our hunt to make your home improvements easier and more eco-friendly in Derry, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Derry, we only included companies that cover the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Derry.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews 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 indicates the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. Still, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Derry's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Derry window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Derry, NH Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, bear 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 kind of window is the best for energy efficiency?
A window's energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or experience, we don't recommend doing it on your own.
How long does it usually take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. 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 the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
