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.

Patio Doors in Indianapolis | Smooth Sliding & Energy Efficient

Update Your View of the Great Outdoors

Our sliding patio doors in Indianapolis connect you to your outdoor living space with easy access and tons of natural light. At T he Window Source of Indy, our patio doors open up your view, let in fresh air, and make it easy to step out to your deck or patio any time of year.

Whether you are building a new home or need to replace an existing sliding patio door, we offer finishes like satin nickel, brass, and oil-rubbed bronze. Every door comes with a stylish, color-coordinated locking handle as standard.

Our sliding glass patio doors create a smooth transition from your living space to your backyard or patio. We customize every door to match your home’s architectural style, and our roller and track system ensures years of dependable, trouble-free operation.

Different from traditional French doors that swing outward and need extra floor space, our sliding patio doors use a single glass panel that simply glides in front of a fixed panel. You can also customize these replacement patio doors with grill options and colors to match your home’s style.

What Makes Our Patio Doors the Best?

It is your home, and we want your new sliding patio doors to fit perfectly. At The Window Source of Indy, we offer a variety of custom sizes and configurations that are ultra-durable, stylish, safe, and cost effective.

Our patio door replacement options include two-, three-, and four-panel styles built with aluminum and steel-reinforced vertical stiles for superior strength and durability. All doors are made with tempered safety glass and meet or exceed code requirements. We offer a full range of Low-E insulating glass options that meet ENERGY STAR Most Efficient program requirements.

For smooth, trouble-free operation, our sliding glass doors have one or more moving panels that glide on oversized dual ball-bearing rollers. These rollers run quietly on a stainless-steel roller track inside an extra-strong fiberglass threshold.

Your family’s safety matters most. Each door comes with options for single, dual, and multi-point locking systems. You can also add a foot-operated security bolt that locks the door at the base while still allowing fresh air and ventilation.
