How Installing Energy-Efficient Windows in Allentown Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: In Allentown, you can lower your indirect greenhouse gas emissions by about 286 pounds per year when you switch to energy-efficient windows.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Allentown
Each window installation company provides varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200. These figures vary based on the specifics of your installation, including type, the location of your home, size, material, number of windows and more.
It's also worth noting that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Allentown home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has noticeable deterioration. Because full-frame installations are more involved, they will raise overall costs. A pocket installation entails installing a new window within the existing frame. So, instead of tearing out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which kind of installation you need, you can consult with your installer and get their recommendation. 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 Allentown
EcoWatch reviews are different from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Allentown, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Allentown.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have nice things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Allentown, PA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost of installing one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
A window's energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window installation companies provide?
Window installers visit your property to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
How long does window installation generally take?
Because the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably 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.
