Old Town Alexandria, Answered
Pressure Washing in Old Town 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 Old Town Alexandria?
Pricing is typically per square foot: brick walkways and stoops run about $0.20–$0.40 per square foot, patios about $0.20–$0.40 per square foot, and driveways about $0.15–$0.35 per square foot. Most single-surface jobs in the 22314 ZIP code finish in two to four hours. 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.
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.
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 and ultimately to the Potomac River, 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 is the difference between pressure and soft washing?
Soft washing (low pressure + chemistry) for siding and roofs; higher pressure for concrete and pavers — matching method to surface is the whole craft.

Our crews work Old Town Alexandria regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
