Pressure Washing in Mount Vernon, IN

Pressure Washing in Mount Vernon, IN

Dependable exterior cleaning for Mount Vernon and Posey County — professional results at honest prices.

Mount Vernon Deserves a Clean Look

Mount Vernon is a community that doesn’t get as much attention as it deserves. As the county seat of Posey County, it sits along the Ohio River southwest of Evansville and serves as the anchor for the surrounding rural area. It’s the kind of town where people know each other, properties have a little breathing room, and folks appreciate good, honest work done at a fair price.

But just like anywhere in the Ohio River Valley, Mount Vernon properties take a beating from the weather. The combination of summer humidity, fall leaves, winter moisture, and spring pollen means exterior surfaces collect dirt, mold, algae, and stains throughout the year. Driveways get that familiar gray-green look. Siding starts showing dark streaks. Decks and patios lose their color. It’s a slow process, so you might not notice how much buildup there is until someone cleans half of it and you see the difference.

Thompson’s Pressure Washing is here to take care of Mount Vernon properties the right way. We’re a locally owned business based in Grayville, IL — not far from Posey County — and we bring professional equipment, the right cleaning chemicals, and genuine care for our customers’ properties. Whether you own a home in town, a farm on the outskirts, or a business on Main Street, we’ll get your property looking its best.

Can you clean metal farm buildings and pole barns?

Yes, and we do this regularly for customers in the Mount Vernon area. Metal siding on barns and outbuildings collects dirt, oxidation, and algae just like anything else. We use the appropriate pressure and cleaning solutions for metal surfaces to remove buildup and restore the appearance without denting or damaging the panels. It’s a popular service for folks with larger rural properties in Posey County.

My concrete has rust stains and tire marks. Can you remove those?

In most cases, yes. Rust stains and tire marks require specific treatments beyond standard pressure washing. We use specialty chemicals designed to break down rust and rubber deposits without damaging the concrete. We’ll take a look at the stains during our assessment and let you know what to expect before we start — no guesswork, no false promises.

How long does a typical house wash take in Mount Vernon?

Most single-family homes take between one and three hours depending on the size of the house, the level of buildup, and how many stories it has. We don’t rush through jobs — we take the time to do it right. We’ll give you a time estimate when we provide your quote so you know what to expect on cleaning day.
