Concrete Cleaning in Descanso, CA.
Concrete Cleaning for Descanso homes, done by licensed San Diego County technicians. Bare concrete — driveways, walkways, patios, garage floors, pool decks — takes a beating from sun, tires, irrigation rust, and foot traffic. We run a hot-water surface cleaner, treat stains with the right chemistry, and if you want the brighter result to actually last, we seal it with a penetrating silane or an acrylic topcoat..

Why is concrete cleaning different in Mountain San Diego?
Mountain concrete collects pine sap and vehicle drip from unpaved drives. We spot-treat sap and oil first so the surface cleaner doesn't smear it across fresh sections of slab.

How does Descanso's climate affect this service?
Mountain moss and organic growth on shaded siding and decks. Mountain concrete collects pine sap and vehicle drip from unpaved drives.
Should I seal my concrete after cleaning?
If you want the result to last, yes. Unsealed concrete is a sponge — oil, rust, and mildew sink in within weeks. A penetrating silane goes invisible and blocks absorption for 3 to 5 years. Acrylic 'wet look' seals give a richer, slightly glossy finish and last 2 to 4 years before needing a refresh.
What is the white haze that came back after it rained?
Efflorescence — calcium and mineral salts migrating out of the slab. Common on newer concrete (under 2 years) or slabs with grading that holds moisture. It wipes off with an efflorescence cleaner, but it will return until the slab fully cures or we correct the moisture path. We'll flag it during the quote.
