Pressure Washing in Ayr

Pressure Washing in Ayr: River-Valley Algae and Township Road Salt

Ayr’s Nith River valley location creates persistently damp conditions that feed green algae and lichen growth on concrete, interlock pavers, and retaining walls — particularly on north-facing surfaces along Northumberland Street, Hall Avenue, and Cedar Street. The village’s older homes feature original limestone and sandstone foundations, poured-concrete steps, and brick walkways that have accumulated decades of biological growth in their porous surfaces. North Dumfries Township applies road salt along Ayr Road (Regional Road 46) and Northumberland Street, and the salt-laden spray migrates onto adjacent residential driveways and walkways through winter. The combination of winter salt damage and spring algae colonization leaves Ayr surfaces looking significantly worse than their structural condition warrants. D&D Home Services uses calibrated pressure washing to safely restore Ayr’s mix of heritage stone and modern concrete — adjusting PSI from 1,000 on century limestone to 3,000 on modern poured concrete to remove all staining without surface damage.
