How Installing Energy-Efficient Windows in Lebanon Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 152 pounds per year on average.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Lebanon
Let's take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Typically, homeowners in Lebanon can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
It's important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Lebanon homeowners $560+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're not sure which type of window installation service you need, your installer can help you out. In general, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lebanon
The EcoWatch Reviews team differs from most reviewers because we examine these companies through a sustainability lens. We have decided to review the top window installation companies in Lebanon mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Lebanon, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Lebanon.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do rate window installers higher 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 most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of installation, quality of parts, cost and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies that provide 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 good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Lebanon, NH Window Replacement FAQs
What is the average cost to install new windows?
The national average cost to install a window is around $600 but can range between $200 and $1,200, depending on a few different 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, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
The most common types of windows for homes include: picture windows, slider windows, awning windows, double-hung and single-hung windows, bay windows, transom windows and casement windows.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
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. 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 doesn't necessarily matter that much. What's most important is that the weather should be dry.
How often do you need to replace windows?
Windows usually last around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
