Your Outdoor Space Should Be an Escape, Not an Embarrassment
Remember when your deck or patio was the place everyone wanted to gather? When you would fire up the grill on a summer evening and actually feel good about inviting the neighbors over? If that feels like a long time ago, you are not alone.
Green Bay's weather is relentless on outdoor surfaces. Long winters bury your deck under snow and ice for months. Freeze-thaw cycles work moisture into every crack and grain. When spring finally arrives, you uncover a surface that has turned gray, splotchy, and slippery with algae. The wood that once had a warm, rich tone now looks like driftwood. The patio stones that once felt clean and solid underfoot are now coated in a green film that makes you think twice before walking on them barefoot.
It is tempting to grab a pressure washer and blast everything clean. But this is where many well-intentioned homeowners cause serious damage. High pressure on wood decking tears up the soft grain, leaving a rough, splintery surface that is actually more prone to moisture damage than before. On composite decking, excessive pressure can void the manufacturer's warranty and permanently mar the surface. And on natural stone, aggressive cleaning can etch the surface, strip sealants, and push water into places it should not go.
Surfaces We Clean Safely
Wood Decks
Cedar, pine, redwood, and pressure-treated lumber all respond differently to cleaning. We adjust our pressure settings, nozzle selection, and cleaning solutions based on the specific wood species and its current condition. Our goal is to remove the gray, weathered layer and biological growth without damaging the wood fibers underneath. After cleaning, we can apply stain or sealant to protect the wood and restore its natural warmth.
Composite Decking
Trex, TimberTech, Azek, and other composite materials require specific care. While these products are marketed as low maintenance, they still accumulate dirt, mold, and mildew, especially in Wisconsin's humid summers. We use manufacturer-recommended cleaning methods that restore the surface without voiding your warranty.
Stone Patios
Flagstone, bluestone, limestone, slate, and other natural stone surfaces need careful cleaning to avoid etching or discoloration. We select pH-appropriate cleaning solutions for each stone type and use pressure levels that clean effectively without damaging the surface or displacing joint material.
Concrete Patios
Poured concrete, stamped concrete, and concrete pavers all respond well to professional cleaning. We remove stains, algae, and weathering to restore the original appearance. Sealing is available to protect the surface and make future maintenance easier.
Brick Patios and Walkways
Brick surfaces accumulate moss, algae, and efflorescence (that white, powdery residue caused by mineral deposits). We clean brick without damaging the mortar joints and treat efflorescence at its source.
Our Deck and Patio Cleaning Process
1. Surface Evaluation
We identify your surface material, assess its condition, note any damage or areas of concern, and recommend the appropriate cleaning approach. If your deck has loose boards, popped nails, or structural issues, we will let you know before we start.
2. Prep and Pre-Treatment
Furniture and planters are moved or protected. We apply surface-appropriate cleaning solutions and allow them to dwell long enough to break down algae, mildew, and embedded dirt. Surrounding landscaping is protected from runoff.
3. Controlled Cleaning
Using carefully calibrated pressure and the correct nozzle for your surface, we clean methodically to achieve even, thorough results. Wood surfaces are cleaned with the grain. Stone and composite surfaces are cleaned using patterns that prevent overlap marks.
4. Rinse, Review, and Protect
We rinse all surfaces and surrounding areas, then review the results with you. If you have opted for staining or sealing, we schedule the application for after the surface has properly dried, typically within 24 to 48 hours depending on weather conditions.
Why Professional Cleaning Beats DIY
No Surface Damage
We know the right pressure for every material. No furred wood, no etched stone, no voided warranties. Your surfaces come out clean and undamaged.
Longer-Lasting Results
Our professional-grade cleaning solutions kill algae and mildew at the root, not just on the surface. Your deck or patio stays cleaner longer than a water-only blast can achieve.
Stain and Seal Ready
Proper cleaning is the essential first step before staining or sealing. We prepare the surface correctly so that finishes adhere properly and last as long as they should.
