Preserving Vincennes’ Character, Inside and Out

Vincennes holds a special place in Indiana history. As the state’s oldest city and the county seat of Knox County, it has a rich heritage that’s visible in its architecture, its tree-lined residential streets, and its historic landmarks along the Wabash River. From the homes near Vincennes University to the neighborhoods surrounding the George Rogers Clark National Historical Park, this is a city that values its past while building for the future.

With that history comes responsibility. Many Vincennes properties feature older brick, wood, and stone exteriors that need careful attention when it comes to cleaning. At the same time, newer residential developments and commercial properties throughout Knox County face the same challenges every property in the Wabash Valley does — persistent mold, algae, mildew, and dirt buildup driven by Indiana’s humidity and seasonal weather swings.

Thompson’s Pressure Washing serves Vincennes and Knox County with the care and professionalism this community deserves. We’re based in Grayville, IL, and while Vincennes is the farthest city in our regular service area, we make the drive because our customers here count on us. We bring the same commercial-grade equipment, soft wash systems, and proper cleaning solutions to every Vincennes job — whether it’s a delicate wash on a century-old brick home or heavy-duty cleaning on a commercial parking lot.

Can you safely clean historic brick homes near downtown Vincennes?

This is one of the most common questions we get in Vincennes, and the answer is yes — with the right approach. Many homes near downtown and around the Vincennes University campus have century-old brick that can be damaged by high-pressure washing. We use soft wash techniques with low water pressure and specialized cleaning solutions that kill algae, mold, and mildew at the root without eroding the brick or deteriorating the mortar joints. It’s the safest way to restore a historic exterior.

Do you work with Vincennes University or other institutional properties?

We’re equipped to handle institutional and commercial jobs of all sizes. If you manage a property near the VU campus, a church, a municipal building, or any other larger facility in Vincennes, we can provide a custom quote and set up a cleaning schedule that fits your needs and budget. We’re happy to work with property managers, facilities directors, and building owners.

How does soft washing differ from standard pressure washing?

Standard pressure washing relies on high water pressure to blast away dirt and grime. That works well on hard surfaces like concrete, but it can damage softer materials like vinyl siding, wood, roofing shingles, and older brick. Soft washing uses much lower water pressure combined with professional-grade cleaning solutions that break down organic growth like algae, mold, and mildew. The chemicals do the work, not brute force. It’s gentler, it’s safer, and the results often last longer because the growth is killed at the source rather than just knocked off the surface.
