How Installing Energy-Efficient Windows in Upper Allen Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, such as:
- Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Upper Allen
Each window installer offers varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
On average, homeowners in Upper Allen can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These estimates are based on specific characteristics of your installation, like type, the location of your home, size, material, number of windows and more.
It’s important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Upper Allen homeowners $310+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In regard to window replacements, there are typically two types that your provider will have: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the complete window, including the sill, trim and frame. Pocket installations are on the simpler end and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you should get.

We have assessed the top window installation companies in Upper Allen primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. 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 pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Upper Allen 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 installer featured in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback 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 cost, quality of installation, quality of parts, warranty, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Lastly, we like to see companies that have a proven 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.
Upper Allen, PA Window Replacement FAQs
How much should window installation cost?
The national average cost of installing one window is about $600 but can range between $200 and $1,200, depending on several factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
Do you really need to use a window installation company?
You should use a window installation company whenever you want new windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best left to the professionals.
When is it time to replace your windows?
Windows usually last around 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have an expert take a look at them to determine if they need any repairs or replacements.
