Why you can trust EcoWatch
Whether you're doing renovations or have old windows, windows play a key role in conserving energy in your home. According to the Department of Energy, heat gained or lost through outdated, drafty windows could be responsible for 25-30% of household energy climate control costs.
That's also bad for the environment because the additional energy required by damaged windows increases your carbon footprint.
Efficient windows are of particular importance in Lebanon, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $316 each year.

How Installing Energy-Efficient Windows in Lebanon Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, such as:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- 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. Upgrading to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- More efficient energy use in your home: In Lebanon where the winters can be very cold, energy-efficient windows lower how much heat is lost through your windows, which makes it easier to keep your home warm.
Estimated Cost of Window Replacement in Lebanon
Each window replacement company provides various services and has different costs depending on several factors.
How Much Do New Windows Cost?
According to our research, the typical cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, such as number of windows, type, size, material, the location of your home and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lebanon homeowners $316+ a year after replacing single-pane windows.
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?
The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose 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 chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Lebanon, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Lebanon.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that offer 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 installation companies 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, IL Window Replacement FAQs
How much does window installation cost?
The national average cost to install a single window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. 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 are the most common types of replacement windows?
The most common types of windows for homes are transom windows, bay windows, awning windows, slider windows, picture windows, casement windows and double-hung and single-hung windows.
Can I replace my own windows?
While it is possible to install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn't be raining, since rain can make the installation harder.
