How Installing Energy-Efficient Windows in Bethlehem Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Bethlehem
Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
Typically, Bethlehem homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at around $600. How much it will cost varies based on several factors, including size, material, type, number of windows, the location of your home and more.
It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Bethlehem home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from several providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re still trying to decide which type of installation you need, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Bethlehem
EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. We’ve decided to evaluate the best window replacement companies in Bethlehem primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Bethlehem so you can find a quality window installation company near you.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company included on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, quality of parts, warranty, professionalism, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest quality service. Still, 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 hefty 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
Because of Bethlehem’s climate, homeowners will want to mitigate rot, water damage and low efficiency. 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.
