How Installing Energy-Efficient Windows in Lebanon Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could help you:

• Decrease your carbon footprint: In Lebanon, you can reduce your indirect greenhouse gas emissions by about 286 pounds per year when you install energy-efficient windows.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 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.

Estimated Cost of Window Replacement in Lebanon

Windows come in different styles, shapes and purposes, so costs and services will vary greatly depending on your project. Below, we go over the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Though the average cost to replace a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, like the location of your home, size, type, material, number of windows and more.

It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Lebanon homeowners $310+ a year when replacing single-pane windows.

Asking for free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant deterioration. Because these installations are more involved, they will raise overall costs. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installer can help you decide which type of installation you need.

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 team assessed dozens of companies before deciding on these. We have decided to evaluate the top window installers in Lebanon mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Lebanon area so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have good feedback about their experience with a certain company, it won’t be 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. Still, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Lebanon’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Lebanon window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
