Overview
Why Commercial Deck & Exterior Surface Washing Is Essential
Commercial decks, patios, loading docks, and exterior hardscape surfaces accumulate algae, mold, oil, biological growth, and weathering stains that create both appearance and safety problems. Algae and mold growth on outdoor surfaces are among the most common causes of slip-and-fall incidents on commercial properties — a significant liability concern that the Occupational Safety and Health Administration (OSHA) identifies as a priority hazard in commercial environments.
Nationwide Maintenance provides professional commercial deck and exterior surface washing throughout New York, New Jersey, and Connecticut. Our technicians use calibrated pressure washing and soft washing techniques — selecting the appropriate method and PSI for each surface material — to safely and effectively clean wood decks, composite decking, concrete patios, stone hardscapes, and loading dock surfaces without causing damage. Combine deck washing with our sidewalk pressure washing and building exterior washing for a comprehensive exterior maintenance program.
All commercial deck and exterior surface washing is scheduled to minimize operational disruption — early morning, evenings, or weekends for outdoor seating areas, and coordinated with your receiving and shipping schedule for loading dock cleaning. Request a free exterior evaluation today.
With over 30 years serving commercial property owners, restaurant groups, hotel properties, and industrial facilities across the Tri-State area, Nationwide Maintenance delivers professional exterior surface washing that protects surfaces, eliminates safety hazards, and restores commercial property appearances.

FAQ
Frequently Asked Questions — Deck & Exterior Surface Washing
Can you wash all types of commercial deck surfaces?
Yes. We clean wood, composite, PVC, concrete, natural stone, and paver deck and hardscape surfaces using calibrated technique and pressure appropriate for each material type. We never apply high pressure to sensitive materials like composite decking or natural stone pavers.
How often should commercial decks be pressure washed?
Most commercial decks and outdoor areas benefit from professional washing twice per year — spring and fall. High-use surfaces like restaurant patios and loading docks may require more frequent service. We will assess your specific surfaces and usage patterns.
Does pressure washing damage wood decks?
Improper pressure washing can raise wood grain and damage wood surfaces. We use calibrated low-to-medium pressure appropriate for commercial wood decking — cleaning effectively without surface damage. We always assess the wood condition before selecting our technique.
Can you clean loading dock surfaces with heavy oil and grease?
Yes. Loading dock cleaning is one of our commercial exterior washing specialties. We use heavy-duty degreaser pre-treatment combined with hot water pressure washing to remove oil, grease, exhaust residue, and organic debris from industrial dock surfaces.
What areas do you serve for commercial deck and exterior surface washing?
We serve commercial properties throughout New York, New Jersey, and Connecticut — including all five NYC boroughs, Westchester County, Long Island, all NJ counties, and statewide Connecticut.
