Pressure Washing in Mount Vernon, IL
Professional Soft Washing & Power Washing Serving Jefferson County
Mildew on the trim. Lichen on the roof. Concrete you'd swear was a different color two summers ago. That's what Jefferson County humidity does, and a hardware-store rental won't fix it. For pressure washing in Mount Vernon that actually lasts, Apex Improvements has been on the ground for years, 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 wet seasons and tree cover that turns half your roof into a moss farm. Winter de-icers that destroy unsealed concrete. Most of what you see growing on your house, roof, and driveway in Jefferson 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 Cedarhurst Center for the Arts, you've probably seen it on a neighbor's house.
What Professional Cleaning Actually Does for Mount Vernon Homes
This isn’t a vanity service in Jefferson County. It’s how you extend the life of your siding, roof, and concrete. Letting biological growth spread doesn’t just look bad. It shortens the life of what your property is made of.
- Roof life. The black streaks you see are caused by a bacteria called 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.
- Reduced summer heat absorption. Dark roofs absorb heat. A clean roof reflects more sun and reduces summer cooling costs, especially on south-facing Mount Vernon homes.
- Resale value. Buyers notice. A clean roof, bright siding, and stain-free concrete show far better in listing photos and walkthroughs.

Our Pressure Washing in Mount Vernon Service Lineup
Every surface needs the method that’s right for it. Soft wash where pressure would do damage. Here’s what we handle for Mount Vernon homes and businesses.
Soft Wash House Washing
Vinyl, Hardie board, stucco, and wood siding all need the same approach: low pressure with the right detergent. We apply a professional soft-wash blend at near garden-hose pressure. This method 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 Mount Vernon
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. Safe for the shingles, safe for the warranty.
Driveway Power Washing in Mount Vernon
For real power washing in Mount Vernon, cold water doesn’t cut it. We use heated industrial pressure washers with commercial surface cleaners. The same equipment big-box retail uses on their lots. Driveways, sidewalks, patios, pool decks, garage floors. For Mount Vernon businesses along Route 15, 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 Mount Vernon and the rest of Jefferson County, both for one-off cleans and recurring schedules. Many of our regular commercial clients are along Route 15 or near Jefferson County Courthouse.

The Mount Vernon Property Maintenance Calendar
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 book most often through the year on Mount Vernon properties.
Spring: Get Ahead of Summer Growth
Jefferson County’s spring pollen settles into siding pores and becomes food for mold through the wet months ahead. A house wash in late March through May prevents the green haze most Mount Vernon homes develop by August. Driveways get hit hard too. Pollen plus humidity equals algae by Memorial Day. We fill up fast in spring, so March bookings get priority.
Summer: Stop the Streaks Before Fall
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. We do most Mount Vernon roof treatments in the heart of summer.
Fall: Leaves, Stains, and Clogged Drains
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. Waiting until spring means dealing with stains that won’t fully come out.

It's the manufacturer-recommended method. Most siding damage calls we get are from people who hired the cheapest quote.
A bacteria called Gloeocapsa Magma. It feeds on the limestone filler in asphalt shingles and spreads fast in humid climates like Jefferson County. Our ARMA-approved soft wash kills it at the cellular level without damaging shingles or voiding your warranty. Plan on re-treating every two to three years for full protection.
Yes. Detergents are biodegradable. We pre-wet your landscaping before applying anything and rinse thoroughly afterward. Years of work in Jefferson County and we've never killed anyone's hydrangeas. Sensitive plants get extra rinse passes.
