What We Do

Three phases, one standard: site handed over spotless.

Post-construction cleaning is a sequence, not a single pass. We work it in the order the trade demands, so each phase sets up the next and nothing gets missed before the owner walks it.

PHASE 01

Rough Clean

Debris removal, sweep-down, and gross dirt clearance once the trades are out. Gets the space safe and workable for finishing crews.

PHASE 02

Minor Clean

Detailed dust, fixtures, surfaces, and interiors. The deep pass that brings the build close to turnover condition.

PHASE 03

Final Detail

The powder-puff finish: glass, touch-points, and last-mile detail so the space is ready for the owner's final walk.

+

Windows & Glass

Interior and exterior window cleaning, including high-rise and hard-access glazing coordinated with site safety.

+

Specialty Services

Caulking detail, pigeon-proofing, and other post-construction specialty scopes handled through vetted crews.
