Thorndale Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Thorndale, PA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Thorndale Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, including:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Better temperature control in your home: Energy-efficient windows can decrease the amount of heat lost through your windows when heating your home.
  • 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.
  • More efficient energy usage in your household: Because the summers can get quite hot in Thorndale, homeowners often rely on their air conditioner a lot. Energy-efficient windows lower the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.

Estimated Cost of Window Replacement in Thorndale

Each window installation company provides varying services and has different prices based on several factors.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost depends on several factors, including size, the location of your home, type, material, number of windows and more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that affects the overall cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

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 replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Thorndale, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Thorndale

EcoWatch is different from most reviewers because we're examining these companies through a sustainability lens. We have evaluated the best window installation companies in Thorndale mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient 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

Because this is a guide for Thorndale, we only included companies that cover the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Thorndale.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Thorndale's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Thorndale window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Thorndale, PA Window Replacement FAQs

What is the typical cost to install new windows?

The national average cost of replacing one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is often influenced by the location of your property, the type and material of the window and the size of the window. 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 kind of window is the most energy-efficient?

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're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

When do I have to use a window installation company?

You should use a window installation professional whenever you want new windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.

How long does window installation generally take?

Because the average installation time is 30 minutes per window, about 16 windows can be installed during an 8-hour work day.
