Alexandria, Answered
Pressure Washing in Alexandria — Common Questions
Does pressure washing in Old Town Alexandria require Board of Architectural Review approval?
Generally, no. Routine pressure washing or soft washing of brick, siding, sidewalks, or stoops is treated as maintenance rather than an exterior alteration, so it typically doesn't require a Certificate of Appropriateness from the BAR. Work that changes the material or appearance of the masonry itself — like repointing mortar or replacing brick — does require BAR review, and we'll flag that distinction if it applies to your property.
How much does pressure washing cost in Alexandria?
Pricing is typically per square foot: driveways run about $0.15–$0.35/sq ft, patios and walkways about $0.20–$0.40/sq ft, and decks about $0.35–$0.60/sq ft. Whole-house exterior packages that bundle siding, driveway, and walkways often run $400–$800 depending on square footage and buildup severity. Every quote is written and line-item, delivered within 24–48 hours of your walkthrough.
Is pressure washing safe for historic Old Town brick and mortar?
High-pressure blasting isn't, which is why we don't use it on historic masonry. Much of Old Town's brick was laid with soft, lime-based mortar that can erode under too much force, so we soft wash historic brick and stone — low pressure combined with a biodegradable cleaning solution and proper dwell time — to lift algae and grime without disturbing the mortar joints.
Does pressure washing wastewater go into Alexandria's storm drains?
It shouldn't, and we don't let it. Alexandria's storm drains carry runoff directly to local streams like Taylor Run and Four Mile Run, and ultimately to the Potomac River and Chesapeake Bay, without treatment. The city's Environmental Management Ordinance implements Virginia's Chesapeake Bay Preservation Act locally, so we use biodegradable detergents and contain and direct wash water away from storm drains and drainage inlets on every job.
What's the difference between pressure washing and soft washing?
Pressure washing uses high-force water alone and belongs on hard flatwork like concrete, pavers, and modern masonry that can handle it. Soft washing uses low water pressure combined with biodegradable detergents to kill algae, mildew, and mold on siding, historic brick, wood decking, and fencing without cracking panels, eroding mortar, or tearing up wood grain. We match the method to the surface and its age on every job.
Do brick sidewalks and stoops in Old Town need special treatment too?
Yes. Old Town's brick sidewalks, herringbone walks, and stone stoops are often as old as the rowhouses behind them, so we treat them the same as historic siding — enough pressure to lift grime and moss without washing the sand and jointing material out from between the bricks.
What's the best season for pressure washing in Alexandria?
Spring and fall are the two best windows. Spring clears winter road-salt residue and early pollen film before it bonds to brick and concrete; fall clears summer algae growth — encouraged by Alexandria's humid, river-adjacent summers — and gets driveways, patios, and siding ready before holiday guests and winter weather arrive.
