Cleveland’s humid summers and wet springs mean concrete patios accumulate algae, mildew, staining, and grime faster than homeowners expect. By mid-summer, many patios that looked clean in April are already showing green buildup in shaded corners.
## What We Remove from Concrete Patios
– Green algae and black mildew
– Food and grease stains
– Rust stains from metal furniture
– Tannin stains from wet leaves
– Moss (especially in shaded areas)
– General atmospheric grime
– Bird droppings
## Concrete vs. Pavers vs. Brick
**Poured concrete:** Responds well to standard hot-water pressure washing with surface cleaners. Older concrete is more porous and may require a second pass for deep stains.
**Concrete pavers:** Lower pressure than poured concrete — pavers can shift and sand can be displaced with too much pressure. We use rotary surface cleaners at appropriate PSI for pavers.
**Natural stone (flagstone, bluestone):** Requires the most care — some stones are sensitive to acidic cleaners. We adjust method per stone type.
**Brick:** Similar to natural stone — brick is porous and requires appropriate pressure and cleaning solutions to avoid damage.
## Should You Seal After Cleaning?
For concrete patios: yes, sealing after cleaning is worthwhile. It slows algae regrowth, protects against staining, and helps the surface handle Cleveland’s freeze-thaw cycles. Give the surface 24–48 hours to fully dry before sealing.
For pavers: paver sealer also stabilizes the joint sand, which helps keep pavers locked in place.
