Situated along I-44 in the heart of south-central Missouri, Lebanon, MO is the county seat of Laclede County and one of the Ozarks' most established communities. From the historic Route 66 corridor running through downtown to quiet neighborhoods near Maplecrest Park and Mount Rose Memorial Park, Lebanon is a city where homeowners take real pride in their properties. The housing stock here spans generations, from well-kept older homes near North Jefferson Avenue to newer builds along the highway corridors, and every one of them faces the same Missouri weather: hot summers, icy winters, and a tornado season that keeps Laclede County in the top tier of storm activity in the state.
At The Window Source of Springfield, we serve Lebanon homeowners with the same high-quality replacement windows, custom-fit doors, and durable siding we've delivered throughout southwest Missouri. Our products are engineered for this climate. Our service is honest, straightforward, and pressure-free. And every project is protected by our lifetime warranty.
Lebanon has its share of contractors. What keeps homeowners coming back to us is a combination of product quality, regional experience, and a no-nonsense approach to every job, from the estimate all the way through installation.
Our reputation is built on trust, and homeowners across the region know we stand by every job we complete.

We provide complete exterior solutions that improve your home's comfort, curb appeal, and long-term value. Whether it's a single window replacement or a full exterior upgrade, we handle every project with the same attention to detail.

Lebanon's climate is hard on older windows. Between the summer heat along the I-44 corridor, the ice storms that roll through Laclede County in winter, and the wind that comes with severe weather season, drafty or failing windows aren't just uncomfortable, they're expensive. We install custom, energy-efficient replacement windows that seal tight, reduce outside noise, lower your energy bills, and give your home a clean, updated look.
Choose from our most popular styles:
All windows feature insulated glass, low-E coatings, and custom sizing for a precision fit that holds up through every season.
A well-installed door does more than look good. It improves security, reduces energy loss, and sets the tone for your entire home exterior. Whether you're replacing a worn front entry or upgrading to a new patio door that opens onto your backyard, we install doors that perform as well as they look in Missouri's demanding climate.
Our door options include:
We'll help you find the right style, finish, and glass option to match your home and your budget, with zero pressure from start to finish.


Your siding is your home's first line of defense against the elements, and in Laclede County that means standing up to summer heat, heavy rain, and the wind that comes with severe weather season. We install vinyl and composite siding systems that protect your home, hold their color, and require almost no maintenance year after year.
Siding options include:
We proudly install Alside siding products, trusted by Midwest homeowners for durability, color retention, and low maintenance in all weather conditions.
