What makes The Window Source of Indy different from other window replacement companies?

At The Window Source of Indy, we combine affordable pricing, premium energy-efficient products, and exceptional customer service. Unlike national chains, we are locally owned and operated, meaning we understand the unique climate challenges in Central Indiana and offer solutions tailored to your home. Our installation crews are highly trained and courteous, and we never use high-pressure sales tactics.

Do your windows meet energy efficiency standards for Indiana homes?

Absolutely. All of our windows are ENERGY STAR® certified and designed with Low-E glass, argon gas insulation, and thermal spacers to maximize efficiency. This helps lower heating and cooling costs, reduces drafts, and keeps your home comfortable year-round—even through Indiana's hot summers and cold winters.

How long does the window installation process usually take?

Most standard window installations are completed within one day, depending on the size of your home and the number of windows. Our process includes pre-inspection, precise measurement, expert installation, and post-installation clean-up. We always respect your property and leave your space cleaner than we found it.

What kind of warranty does The Window Source of Indy offer on windows and doors?

We provide an industry-leading Limited Lifetime Warranty that covers frames, sashes, hardware, and even glass breakage. Many of our windows also include a transferable warranty, which adds resale value to your home if you decide to sell.

Do you offer financing options for window or door replacement projects?

Yes, we offer flexible financing plans to fit various budgets, including low monthly payments and zero-interest options for qualified buyers. Our goal is to make high-quality window replacement accessible and stress-free, no matter your budget. You can easily apply during your free consultation with no obligation.

“The company to use if your needing window replacement, Fair pricing and honest fast work.”

Tom Reavis, GA

“Fantastic Company and true to their word! The crew was so professional and polite. We had our entire house of windows done and it only took 2 days. The quality of these windows are amazing and we couldn’t be happier! Don’t pay the high price that other companies want. This is the real deal!”

Jennifer Rochester, NH

“The Window Source of Tulsa was recommended to us. We received bids from three window replacement companies. Window source had the best product at the best price. The installation was on time and professional. We were kept informed through out the process. We are very pleased with the final product. About two weeks after the windows were installed I broke the outside pane of one window while mowing the yard. I contacted Window Source and told them what had happened, offering to pay for the replacement. They replaced the window free of charge. They are a pleasure to do business with.”

Alan McIntyre, OK

“Excellent service, product, and less than half the price of the other 2 estimates I had. Installer cleaned up after himself and was very professional.”

Ian Gollahon, OK
