Pressure washing means forceful water aimed at tough surfaces: concrete aprons, steps, garage slabs and stone. Rob, who runs a family business out of Woodstock and sends no subcontractors in his place, does it for homes in Union, IL, where mud, road salt and farm-lot grime build up on flatwork. Work begins at $75. Pictures of the surfaces, texted to (815) 451-0106, get you a quote.
Pressure washing looks simple, which is exactly why it goes wrong so often. A rented machine, a bare concrete slab and a free Saturday sounds like a good plan until the wand leaves pale stripes in the surface or sends water into a garage door seal. Union homes have their own variations of the usual mistakes.
This page is organized around those mistakes: what people do, why it backfires on rural and village lots, and what Rob does differently. If you would rather hand the job off, he will quote it after seeing pictures.
Mistake one: using full pressure on everything
Concrete tolerates strong water better than anything else on the property, but even concrete has limits. Old slabs with surface spalling lose more of their top layer when blasted. Wood steps, siding, window seals and mortar joints suffer far sooner. High pressure can drive water behind seams and into places that stay damp for weeks.
Rob matches the tool to the surface. Flat concrete gets strong, even passes. Anything softer gets a gentler approach, which is often a job for soft washing instead. The comparison guide lays out which method belongs where.
Mistake two: ignoring where the water runs
A Union lot is mostly open ground, which makes it tempting to let rinse water go wherever the slope takes it. That can wash dirt into a flower bed, across a gravel drive or toward a well head or septic field. Slabs that slope toward the garage can push water under the door.
Before starting, Rob checks the grade and the drainage direction, and sweeps debris away from the low point so it does not clog a drain or pond. He also asks where the well and septic components are, so rinse water is directed away from them.
Mistake three: treating rust and oil like dirt
Equipment pads and garage entrances collect oil, hydraulic fluid and tire marks. Orange stains below a spigot or sprinkler on a well system come from iron in the water. Neither lifts with water alone, and pressure can spread the oil deeper into pores instead of removing it.
Rob tells you up front which marks will fade and which may shadow. For salt crust and white bloom on older concrete, see the guide on salt, rust and efflorescence.
- Oil and fluid drips near garages
- Rust from iron-rich well water
- White bloom from salt and moisture
- Dried mud and clay tracked from field edges
- Green film on shaded steps
Mistake four: skipping the edges and the cracks
Cracks in a slab let water under the concrete, and winter freezes that water into wedges. A pressure wash that blasts a crack open at full strength can lift small chunks and speed the problem. Weeds growing at the seams tend to return fast if the root stays.
Rob works along cracks with a lighter touch, tells you where concrete is failing, and lets you know when sealing or patching is a better investment than more cleaning. A mason or concrete contractor handles real structural repair.
Mistake five: picking the wrong week
Pressure washing in freezing conditions leaves a skin of ice on the slab. Water left on concrete in a hard freeze can worsen surface scaling. The workable window in northern Illinois runs from spring thaw into late fall, with the best results when temperatures stay above freezing for a day or two afterward.
Rob likes to schedule concrete after salt season is clearly over, and again in early fall before winter treatments start. If you plan to seal concrete, wash first and let it dry fully, which takes longer in shade.
Pressure Washing through the year in Union
Spring
Rinse off winter salt and mud once the ground thaws. Check slabs for new cracks or heaving before water goes into them.
Summer
Good time for equipment pads, steps and the garage apron. Surfaces dry quickly, so staining is easier to judge.
Early fall
Clean before leaf litter and winter. A clean slab shows ice-melt residue and cracks more clearly.
Winter
Do not wash in freezing weather. Shovel and use ice melt sparingly, since heavy salt is hard on concrete.
Getting a quote
A clean slab gives a house a stable look, and the work is over before you know it when it is done right. If your apron, steps or garage pad are marked up by winter salt and field mud, text pictures to Rob at (815) 451-0106. He will let you know which parts a wash will help, which parts it will not, and when he can come out.
