Concrete Takes a Beating in Wisconsin
Concrete is everywhere on your property. Sidewalks, patios, pool decks, garage floors, steps, retaining walls, and of course, driveways. It is one of the most durable building materials available, but that does not make it immune to the effects of time and weather. In Green Bay, concrete faces some of the harshest conditions in the country.
Every winter, the freeze-thaw cycle goes to work on your concrete. Water seeps into the porous surface, freezes, expands, and creates tiny cracks. Those cracks allow more water in during the next cycle, and the damage compounds over time. Road salt and deicing chemicals accelerate the process, causing surface spalling and that flaky, pitted appearance that makes concrete look decades old.
Then there are the stains. Oil from vehicles, rust from metal furniture and tools, leaf tannin, fertilizer, paint drips, and the ever-present algae and mildew that thrive in Wisconsin's humid conditions. These stains do not just sit on the surface. Concrete is porous, and stains penetrate deeper with every passing season, making them progressively harder to remove.
You have probably tried cleaning your concrete with a garden hose, or maybe a consumer-grade pressure washer from the hardware store. The results were likely disappointing: streaky lines from the wand, stains that barely faded, and a surface that looked dirty again within a few weeks. That is because effective concrete cleaning requires the right equipment, the right cleaning agents, and the right technique, all working together.
Concrete Surfaces We Clean
Sidewalks and Walkways
The paths around your home see constant foot traffic and accumulate dirt, algae, and staining quickly. We restore sidewalks to a clean, safe, and attractive condition that complements the rest of your property.
Patios and Entertaining Areas
Your patio should be a place you enjoy, not a surface you are embarrassed by. We remove years of grime, food stains, and biological growth to restore your outdoor entertaining space to a condition you are proud of.
Pool Decks
Safety is paramount around pool areas. Algae and mildew on pool decks create dangerously slippery conditions, especially when wet. We clean pool deck surfaces thoroughly and can apply non-slip sealants for added safety.
Garage Floors
Oil stains, tire marks, road salt residue, and general grime accumulate on garage floors over the years. We deep-clean garage floors and offer sealing options that protect the surface and make future cleanup easier.
Retaining Walls
Concrete and block retaining walls develop algae, moss, and efflorescence that obscure their appearance. We clean these vertical surfaces carefully, restoring their original look without damaging the structure or mortar joints.
Commercial Concrete
Parking lots, loading docks, warehouse floors, and building perimeters all benefit from professional concrete cleaning. We handle commercial-scale projects efficiently with equipment designed for large surface areas.
Our Concrete Cleaning Process
1. Surface Evaluation
We assess the concrete's condition, identify the types of stains present, check for cracks or damage that need attention, and determine the best cleaning approach for your specific surface and situation.
2. Stain Pre-Treatment
Oil stains, rust, and heavy organic staining receive targeted pre-treatment with specialized solutions. These products break down the stain from within the concrete's pores, allowing for more complete removal during the cleaning phase.
3. Surface Cleaning
We use commercial rotary surface cleaners that deliver uniform pressure across a wide swath, eliminating the streaky "zebra stripe" pattern that handheld pressure wands leave behind. The result is an even, consistent clean from one edge to the other.
4. Sealing (Optional)
After cleaning, we offer concrete sealing to protect your investment. A quality sealer fills the pores of the concrete, preventing water penetration, reducing stain absorption, and slowing the freeze-thaw damage that Wisconsin's climate inflicts on unprotected surfaces.
The Case for Concrete Sealing
Cleaning your concrete is a great start, but sealing it takes the protection to another level. Here is what a quality concrete sealer does for your property:
Freeze-Thaw Protection
Sealer prevents water from penetrating the concrete surface, dramatically reducing the freeze-thaw damage that causes spalling, cracking, and surface deterioration in Wisconsin's climate.
Stain Resistance
Sealed concrete resists oil, grease, and other stains because the sealer fills the pores that would otherwise absorb them. Spills can be wiped up before they become permanent.
Easier Maintenance
Sealed surfaces are much easier to keep clean. Dirt, debris, and organic growth have a harder time gaining a foothold on a sealed surface, and routine cleaning produces better results with less effort.
Enhanced Appearance
Depending on the sealer type, you can achieve a natural matte finish or a subtle wet-look sheen that enhances the color of your concrete. Stamped and decorative concrete especially benefits from the color enhancement that a quality sealer provides.
