Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a large impact on home energy conservation. Drafty or leaky windows can make your AC or heater work extra hard in the summer or winter.
That’s also bad news for the environment, as the extra energy used by drafty windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window replacement companies based on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Lower Gwynedd Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Reduce your carbon footprint: In Lower Gwynedd, you can cut your indirect greenhouse gas emissions by about 286 pounds per year after you switch to energy-efficient windows.
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Lower Gwynedd
Windows come in various shapes, purposes and styles, so costs and services will differ greatly depending on your project. Below, we describe the typical cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
On average, Lower Gwynedd homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at approximately $600. This is because window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Asking for free quotes from multiple installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Lower Gwynedd
EcoWatch reviews are different from most reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Lower Gwynedd and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Lower Gwynedd, we only included companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Lower Gwynedd.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have nice things to say about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, 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
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers 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.
Lower Gwynedd, PA Window Replacement FAQs
How much does a window install cost?
The national average cost of installing one window is around $600 but can range between $200 and $1,200, based on several factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, keep 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 are the different types of windows?
The most common types of windows for homes are awning windows, transom windows, bay windows, double-hung and single-hung windows, picture windows, slider windows and casement windows.
Do you really have to use a window installation company?
Unless you have experience with home improvement projects and have all the necessary tools to replace your own windows, we recommend hiring a professional. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
How do you know it’s time to replace your windows?
Windows usually last about 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
