How Installing Energy-Efficient Windows in Upper Darby Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to think about making the switch:
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Upper Darby, that’s about 286 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Upper Darby
When researching window installation, each company provides varying services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
On average, homeowners in Upper Darby can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost is based on several factors, including size, material, the location of your home, number of windows, type and more.
It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Upper Darby home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Upper Darby
The EcoWatch Reviews team is different from most reviewers because we examine these companies through a sustainability lens. We have reviewed the top window installers in Upper Darby primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Upper Darby, we gave more points to companies that serve the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Upper Darby.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, professionalism, quality of parts, cost, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Upper Darby’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Upper Darby window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Upper Darby, PA Window Replacement FAQs
How much does a window install cost?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is generally influenced by the size of the window, the type and material 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 hundreds of dollars a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don’t have the time or know-how, we recommend hiring a professional.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all your windows together is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or leaky, you can replace just those.
