How Installing Energy-Efficient Windows in Bethlehem Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient windows can help lower that amount, which helps you save $280 a year on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Bethlehem
Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, like number of windows, the location of your home, size, type, material and more.
It's important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Bethlehem homeowners $280+ a year when replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the entire window, including the sill, frame and trim. A pocket installation means replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window installation company can advise you on the best type for your project. In Bethlehem, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Bethlehem
EcoWatch reviews are different from other reviews, as we evaluate these companies through a sustainability lens. We've assessed the top window installation companies in Bethlehem mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
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 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
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including warranty, quality of parts, quality of installation, cost, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer 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 well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Bethlehem's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Bethlehem window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Bethlehem, PA Window Replacement FAQs
How much does a window install cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is often influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are several different types of windows you can get for your home, such as awning windows, bay windows, transom windows, picture windows, casement windows, double-hung and single-hung windows and slider windows.
Can you replace your own windows?
Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
