Top-Rated Pressure Washing in Simpson, IL
Power Washing & Soft Wash Specialists Serving Johnson County
Black streaks on the roof. Green film on the north side of the house. A driveway that looks like it's wearing a coat. That's what Johnson County humidity does, and a hardware-store rental won't fix it. For pressure washing in Simpson done right, Apex Improvements brings the equipment that actually matters, with heated industrial equipment, professional-grade cleaning solutions, and methods safe on whatever your property is built from.
What Southern Illinois Weather Does to Your Home
Long humid summers and dense tree cover. Pollen, leaves, and tannins drop onto every surface. Winter de-icers that destroy unsealed concrete. Most of what you see growing on your house, roof, and driveway in Johnson County isn't dirt. It's living growth: algae, mold, lichen, mildew. Cold water knocks the leaves off and the root stays alive, which is why a hardware-store rental gives you clean siding for six weeks before everything comes back. If you live near Simpson community area, you've probably seen it on a neighbor's house.
Why It's Worth Hiring Out in Simpson
In our climate, exterior cleaning protects materials more than it impresses neighbors. Letting biological growth spread doesn’t just look bad. It shortens the life of what your property is made of.
- Extend shingle life. The streaks running down your shingles are colonies of Gloeocapsa Magma. It feeds on the limestone filler in your asphalt shingles. Untreated, it shortens roof life by years.
- No more slick patches. Algae on sidewalks and driveways is a real slip-and-fall risk, especially after spring rain. We strip the slick layer down to bare concrete.
- Cooling cost savings. Dark roofs absorb heat. A clean roof reflects more sun and reduces summer cooling costs, especially on south-facing Simpson homes.
- Appraised value. Buyers notice. A clean roof, bright siding, and stain-free concrete show far better in listing photos and walkthroughs.

Pressure Washing in Simpson — Our Full Service List
Pressure has its place and so does soft washing. We use both, depending on the surface. Here’s what we handle for Simpson homes and businesses.
Soft Washing in Simpson: House Exteriors
Vinyl, Hardie board, stucco, and wood siding all need the same approach: low pressure with the right detergent. We apply a specialty detergent mix at near garden-hose pressure. Soft washing in Simpson kills mold and mildew at the root, which is why your home stays cleaner two to three times longer than after a pressure-only wash.
Soft Wash Roof Cleaning in Simpson
Black streaks on shingles aren’t going anywhere with high pressure. They need to be killed at the cellular level. Our non-pressure roof treatment follows ARMA (Asphalt Roofing Manufacturers Association) guidelines. No shingle damage, no voided warranty, no walking on the roof.
Power Washing in Simpson: Driveways & Concrete
For real power washing in Simpson, cold water doesn’t cut it. We use heated industrial pressure washers with commercial surface cleaners. The same equipment commercial property managers specify. Driveways, sidewalks, patios, pool decks, garage floors. For Simpson businesses along Route 147, we handle storefront and sidewalk maintenance too.
Full Gutter Maintenance
Gutter overflow rots fascia and cracks foundations over time. We do full manual cleanouts and downspout flushing. If you’re tired of the fall ladder routine, ask about gutter guard installation.
Commercial Exterior Cleaning
Storefronts, restaurants, dumpster pads, office building exteriors. We work with property managers and HOAs across Simpson and the rest of Johnson County, both for one-off cleans and recurring schedules. Many of our regular commercial clients are along Route 147 or near Bay Creek.

Seasonal Maintenance for Simpson Properties
Most homeowners think of pressure washing as a once-in-a-decade thing. In our climate, that's how small problems become expensive ones. Here's what we find works best through the year on Simpson properties.
Spring: The Pollen Cleanup
Johnson County’s spring pollen settles into siding pores and becomes food for mold through the wet months ahead. A house wash in spring prevents the green haze most Simpson homes develop by August. Driveways get hit hard too. Pollen plus humidity equals algae by Memorial Day. Schedule before April to lock in a spring slot.
Summer: Roof & Algae Defense
July and August humidity is peak growing season for roof algae. Dark roofs absorb more heat, which dries out shingles and drives up cooling bills. A soft-wash roof treatment in early summer kills the bacteria and reflects more sunlight back. Roof streaks become impossible to ignore in Simpson by July.
Fall: Pre-Freeze Maintenance
Fallen leaves contain tannins. Natural acids that stain concrete permanently if you let them sit too long. Clogged gutters during fall rains lead to fascia rot and foundation issues. Schedule the deep clean and a full gutter cleanout before the first hard freeze. Once tannins set in, no amount of pressure will lift them. They need chemical treatment.
