How Installing Energy-Efficient Windows in South Lebanon Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

• Save on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In South Lebanon, that’s about 286 pounds per year on average.
• 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 property if you decide to sell.

Estimated Cost of Window Replacement in South Lebanon

When considering window installation, each company provides varying services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Generally, South Lebanon homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. How much it will cost is based on several factors, including the location of your home, type, size, number of windows, material and more.

What Services do Window Installers Offer?

The first step when considering an installation is to clarify whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation means replacing a window without removing the entire frame, which is generally less expensive than a full-frame installation.

If you’re still trying to decide which kind of installation you need, you can consult with your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in South Lebanon

In our hunt to make your home improvements easier and more eco-friendly in South Lebanon, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:

Service Area

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

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, quality of installation, cost, warranty and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of South Lebanon’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of South 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.
