20 Best Window Companies in Bethlehem, PA (2025 Reviews)

How Installing Energy-Efficient Windows in Bethlehem Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, including:

• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
• Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that amount, which helps you save more on your bills.
• 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.

Estimated Cost of Window Replacement in Bethlehem

Windows come in different purposes, styles and shapes, so costs and services will vary tremendously based on your project. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.

It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Bethlehem homeowners $301+ a year when replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations involve replacing the complete window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has noticeable rot. These installations are more involved and will increase the overall cost. Pocket installations are simpler and won’t carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you’re still debating which type of installation to get, you can ask your installer and get their advice. The choice 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 Bethlehem

In our search to make your home improvements easier and more eco-friendly in Bethlehem, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We’ve evaluated the best window replacement companies in Bethlehem primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Bethlehem, we only included companies that serve the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Bethlehem.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
