Why you can trust EcoWatch
Whether you're updating for style or have damaged windows, windows play a important role in conserving electricity in your home. Drafty, leaky windows could lead to spending more on electricity bills during the winter or summer months.
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 Mount Lebanon, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $313 a year.

How Installing Energy-Efficient Windows in Mount Lebanon Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to make the switch:
- More efficient energy usage in your household: In Mount Lebanon where the summers can be quite hot, energy-efficient windows decrease the amount of cool air that is lost through your windows, making it easier to keep your house cool.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
- More efficient energy use in your household: Because the winters can get very cold in Mount Lebanon, homeowners often rely on their heater during that time. Energy-efficient windows cut back on how much heat is lost through your windows, making it easier to keep your home warm.
Estimated Cost of Window Replacement in Mount Lebanon
When researching window installation, each company offers different services and prices. Let's go over some typical costs and services.
How Much Do New Windows Cost?
On average, Mount Lebanon homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at about $600. This is due to the fact that the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
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 many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Mount Lebanon homeowners $313+ each year after replacing single-pane windows.
We advise requesting free quotes from multiple window installation companies 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 replaces the entire window, including the windowsill, frame, trim and the window panes. As this type of installation is more involved, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without taking out the complete frame, which is usually less expensive than a full-frame installation.
If you're still debating which type of installation to get, you can talk to your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Mount Lebanon
EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Mount Lebanon, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Mount Lebanon.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you get. 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 most customers don't have nice feedback about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not 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 considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Mount Lebanon's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Mount 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.
Mount Lebanon, PA Window Replacement FAQs
What is the typical cost to install new windows?
The average cost of installing a window ranges from $450 to $650. There are a variety of factors that influence the cost, including the number of windows, your property's location, styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows and local labor costs.
What are the kinds of windows?
There are several different kinds of windows you can get for your house, including slider windows, casement windows, double-hung and single-hung windows, awning windows, bay windows, picture windows and transom windows.
Can I install my own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don't have the time or know-how, we don't recommend trying it.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, because rain can make the installation harder.
