20 Best Window Companies in Lebanon, TN (2025 Reviews)

How Installing Energy-Efficient Windows in Lebanon Saves You Money

There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

• Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save more on your bills.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 477 pounds per year on average.

Estimated Cost of Window Replacement in Lebanon

Let’s take a look at the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the national average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. 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 offer door replacements, which carry a higher price tag.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

We advise requesting free quotes from several window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

When it comes to window installations, in general there are two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the complete window, including the sill, frame and trim. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re still debating which kind of installation you need, you can ask your provider and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Lebanon

In our hunt to make your home improvements easier and more eco-friendly in Lebanon, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:

Service Area

Since this is a guide for Lebanon, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Lebanon.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

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 nearly every category, including cost, quality of installation, warranty, professionalism, quality of parts and more.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor 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 will earn higher rankings by our standards. We like to see at least ten years of experience.
