We clean decks using specialized chemical solutions and gentle low-pressure techniques that remove dirt, mildew, and gray weathering without damaging wood fibers or composite materials.

Unlike aggressive high-pressure washing that splinters wood, raises grain, and creates fuzzy surfaces requiring sanding, our chemical-based approach does the cleaning work through biodegradable solutions that break down contaminants.

We apply professional deck cleaners that penetrate surfaces, lift embedded dirt, kill mold and mildew, and restore natural colors—then rinse gently with controlled low pressure that removes loosened material without surface damage.

This gentle method is essential for preserving deck integrity and appearance. High-pressure washing might seem effective, but it actually destroys wood by stripping away soft grain, creating deep gouges, and forcing water into boards that causes swelling and accelerated rot.

Composite decking scratches and etches under high pressure, permanently damaging the protective surface layer. Our chemical cleaning approach respects these materials, removing years of buildup while maintaining the smooth surfaces that make decks comfortable to walk on barefoot and safe for children playing.


Can you remove the gray weathering from my wood deck?

Yes, that’s exactly what our chemical cleaning excels at. Gray weathering is dead wood fibers and UV damage on the surface. Our specialized solutions gently lift this layer away, revealing the natural wood color beneath without the splintering and grain-raising that pressure washing causes.

Will chemical cleaning work on composite decking?

Chemical cleaning is actually ideal for composite materials. Composites have a protective cap layer that high pressure scratches and damages permanently. Our gentle chemical approach cleans thoroughly while preserving this protective surface, maintaining the low-maintenance properties that made you choose composite in the first place.

How do you remove mold and mildew from my deck?

Our professional cleaning solutions contain biocides that kill mold and mildew at the root level. The chemicals do the work of breaking down and lifting organic growth, so we only need gentle rinsing pressure to remove it. This approach is far more effective than pressure alone, which just blows surface growth away temporarily.

Is it safe to walk on the deck immediately after cleaning?

Yes, once rinsed and dry, your deck is completely safe. Our cleaning solutions are biodegradable and rinse away completely. If we apply sealer or stain after cleaning, we’ll specify appropriate drying time before the deck can handle foot traffic—usually 24-48 hours depending on product and weather.

Will cleaning prepare my deck for staining, or do I need sanding too?

Our chemical cleaning provides excellent preparation for staining without sanding in most cases. The cleaning process opens wood pores and creates the slightly textured surface that stain needs for proper penetration and adhesion. Heavy splinters or damage might need spot sanding, but gentle chemical cleaning eliminates the extensive sanding that pressure-washed decks require.

Chemical cleaning opens wood pores perfectly for stain and sealer application. If you want protective coatings after cleaning, our process provides ideal preparation without the over-aggressive surface damage that compromises coating adhesion and performance.
