Alexandria courtyards and pool surrounds — brick, flagstone, travertine — grow a slick algae film that turns dangerous in summer.
Our method
Surface-matched pressure (brick and mortar joints get gentler treatment than concrete), algaecide post-treatment, and runoff control that respects the tight lot lines and neighbors that define this city.
Historic district note
Exterior cleaning doesn’t need BAR approval — it’s the fastest curb-appeal win an Old Town rowhouse can get.
