How Installing Energy-Efficient Windows in Lebanon Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that number, which helps you save more on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Lebanon
Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost you varies based on several factors, like number of windows, the location of your home, size, material, type and more.
It's also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Lebanon home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you're still trying to decide which kind of installation you need, you can consult with your installer and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Lebanon
In our hunt to find the most reliable, eco-friendly window installers in Lebanon, the EcoWatch team assessed many companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Lebanon so you can find a quality window installation company near you.
Work Quality
When selecting 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 higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that give you 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 quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Lebanon, CT Window Replacement FAQs
What is the average cost to install windows?
The average cost to replace one window can range between $450 and $650. There are many factors that influence the cost, which include styles and sizes of windows, your property's location, local labor costs, the number of windows, how energy-efficient the windows are and the materials used in designing the windows.
What are the different kinds of windows?
The most common types of windows for homes include: bay windows, double-hung and single-hung windows, awning windows, picture windows, casement windows, slider windows and transom windows.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The window installation process is quite involved 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 professional is a faster, more efficient and safer option.
How long does window installation usually take?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.
