Board and Surface Preparation
To keep your exterior area clean for family use, the pro begins by clearing off loose leaves, pine needles and dirt trapped between the boards.

For Illinois homeowners, professional deck cleaning supports curb appeal and makes an outdoor living space easier to enjoy. Local specialists tailor each washing service to the boards instead of treating every surface the same.

To keep your exterior area clean for family use, the pro begins by clearing off loose leaves, pine needles and dirt trapped between the boards.
Landscaping close to the deck is thoroughly saturated with clear water and shielded with protective covers to guard your plants.
A tailored cleaner sits on the deck boards to dissolve slick algae, fungal growth spores and gray wood fibers. The pro then rinses the floorboards using low water pressure.
Stairs, spindles and top rails are washed by hand. After a complete final rinse, the pro reviews the results with you in the area. A measured softwash method releases each contaminant, helps remove algae, and breaks up mildew and algae film, grime, and years of dirt. This approach gives outdoor boards a clean finish without harsh blasting.
If your boards currently look dull, dark, or covered in green growth, a careful washing brings back their natural tone. Cedar, pressure-treated pine, and redwood feature soft fibers that easily strip or split if scrubbed roughly. The pro rinses these materials with low water pressure after a specialized washing mix breaks down surface grime. Tropical hardwoods receive dedicated soaking to clear deep-set dirt.
Synthetic deck boards retain their structure for decades, but mold spores and dirt collect in the surface texture. The pro lifts stuck-on residue from composite and PVC materials while following standard board care recommendations.
Surrounding masonry surfaces suffer from the same organic growth as high elevation decks. Concrete stairs, stone patios, pavers, and pool aprons are rinsed clear of slippery film. Pool deck cleaning services can address hardscape next to the swimming zone as part of the same project. A careful rinse can clean your pool deck, protect your pool, and improve the walking surface.

Pricing for specialist surface care starts at $150. The overall footprint in square feet acts as the primary price driver, but the physical condition of the timber or composite boards is equally important. Decks heavily coated with gray sun-damaged fibers, stubborn leaf tannins, or slick green growth take longer to wash safely. Architectural elements like balusters, guardrails, and stair treads call for manual detailing. Heights, steep backyard terrain, or tight gate entries can also influence the labor involved. If you choose to apply a protective oil, finish, or clear seal after washing, that work is quoted as an additional standalone job. You always receive your complete price before any washing starts.

Washing an outdoor surface in the area clears away much more than visible dirt and fallen leaf marks. Smooth wooden boards become very slick when growth and fungal growth spread across the surface, especially after a steady rain. These organisms trap persistent moisture against the timber, causing early decay around nails, screws, and joists. Intense sunlight also breaks down wood cells, creating loose fibers that quickly turn into painful splinters. Removing this build-up keeps steps safe underfoot and prevents structural wood from rotting prematurely. Furthermore, fresh finish or sealant requires a completely clear wood surface to absorb correctly and last.

If your outdoor surface looks dark, weathered or coated in green film, high pressure is not the right tool for the job. Pushing extreme water pressure into soft pine or cedar gouges lines into the wood and leaves it fuzzy. A pro in the area applies a surface wash that dissolves growth, pollen film and leaf marks at the chemical level. The surface is then washed down with a gentle, low-pressure fan spray moving steadily along the boards. Synthetic materials like composite and PVC are washed in line with the board manufacturer instructions to keep the factory surface safe. People comparing pressure washing services with professional pressure washing in Markham can choose a method suited to the surface.
Even durable composite materials in the area suffer when cold weather lingers. Packed drifts hold wet leaf layers against synthetic planks for months. Clearings with hard shovels cause surface scuffs, while white chemical crystals discolor composite patterns. Trapped liquid freezes and expands inside microscopic gaps. Warmth reveals dark spots and slick growth across the synthetic boards. A low-pressure rinse removes these stubborn, dull winter deposits safely.
Outdoors in the area, surface lumber takes a beating from heavy natural fall. Pine needles jam tightly between planks, blocking air flow. Oak and maple foliage decays under rain, soaking brown marks into the wood fibers while spring covers everything in tiny propeller seeds. Controlled spraying along each board lifts those set-in tree marks completely.
Constant sun exposure and rainfall break down raw wood fibers, turning surface boards gray and attracting fungal growth. Marks cannot soak into weathered or dirty timber. Thorough washing strips away these damaged surface fibers, and a brightener balances the natural wood tone. The boards must dry fully before applying any coat of sealer. Sealing or finishing can be added as a separate service with a separate quote once your pro sees the washed surface.
We connect you with local pros who wash structures in the area, and a few easy steps will keep the surface clear afterward. Sweep off wet leaves and needles before dark marks sink into the material. Clear the narrow spaces between boards so rainwater drains away instead of standing. Lift heavy flower pots and outdoor rugs that collect moisture against the floorboards. Cut back tree branches that block drying sunlight, and use a garden hose to rinse away pollen before it forms a dull film over the boards.
