Alexandria, VA / 4.7 rating from 15687 reviews / Fire damage restoration service

Best for: Northern Virginia homeowners dealing with water damage that led to mold, who want one company to handle extraction, remediation, and rebuild under one roof with insurance coordination.

The broader company operates eleven locations across Virginia, Maryland, North Carolina, South Carolina, and Washington DC. For mold remediation specifically, confirm that your area is served by the Alexandria office and not a more distant location.

Review snapshot: Techs like Cesar, Lloyd, Bertrand, Wayne, and Isac draw consistent praise for knowledge and friendliness. But 61 reviews at 1-3 stars across 15,687 total reveal a pattern of aggressive upselling, inflated repair quotes, and poor follow-through on callbacks and scheduling.

Service area: Clean Sweep is headquartered in Westminster, Maryland (Carroll County). They serve Carroll, Frederick, Baltimore, Harford, Howard, Anne Arundel, and Montgomery counties in Maryland, plus Adams and York counties in Pennsylvania.

Service area: Mr. Vac is headquartered in Grand Junction, Colorado, with a second office in Glenwood Springs and service coverage in the Vail Valley. They serve the broader Western Slope region including Aspen, the Roaring Fork Valley, and surrounding communities.
