How Installing Energy-Efficient Windows in Allentown Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if your home is on the older side.
- Save money on electricity bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
Estimated Cost of Window Replacement in Allentown
Windows come in various 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 market research, the national average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which carry a higher price tag.
It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Allentown home can mean an average energy savings of $236 to $319 per 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant deterioration. These installations are more involved and will raise the total cost. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re still debating which type of installation you need, you can ask your provider 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 Allentown
The EcoWatch Reviews team differs from most reviewers, as we evaluate these companies through a sustainability lens. We have decided to assess the top window replacement companies in Allentown mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Allentown, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Allentown.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, cost, quality of installation, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, 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
Due to Allentown’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Allentown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
