How Installing Energy-Efficient Windows in Epping Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Reduce your carbon footprint: Since 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- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Epping
When researching window installation, each company offers different services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
Generally, Epping homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. But costs differ remarkably depending 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 replacements, which will add extra costs to your project.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Epping homeowners $435+ each year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two types of window installation services you can get: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations are on the simpler end and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Epping, the decision will mostly be based on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Epping
The EcoWatch Reviews team is different from most reviewers since we look at these companies through a sustainability lens. We have reviewed the top window installation companies in Epping mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers higher marks 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 highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, cost, warranty, quality of installation, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Epping, NH Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is usually influenced by the size of the window, the location of your property and the type and material of the window. Also, remember 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 most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with 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 professionals cover the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.
How long does window installation usually take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
What time of year is a good time to replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure 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.
