Post-construction cleaning removes the fine dust, drywall residue, paint overspray, adhesive residue, and debris left behind after renovation or new construction. The service typically involves multiple passes: a rough clean to remove large debris, a detailed clean of all surfaces, and a final polish for move-in readiness. Drywall dust is especially pervasive — it settles into HVAC vents, light fixtures, cabinets, and every horizontal surface. Our crews use HEPA vacuums and specialized techniques to achieve a truly clean result.
Mill Valley is located in Marin County (North Bay). Affluent wooded community at the base of Mount Tamalpais with redwood-surrounded homes. The local utility provider is PG&E.

Post-Construction Cleaning in Mill Valley — FAQ
How many cleaning passes are needed after construction?
Typically 2–3 passes. Drywall dust resettles after the first cleaning, so a second and sometimes third pass is needed for a truly dust-free result.
Can you clean HVAC ducts after construction?
We clean vent covers and accessible ductwork openings. For full duct cleaning, we recommend a specialized HVAC duct cleaning service.
When should post-construction cleaning happen?
After all construction work is 100% complete, including painting, trim installation, and fixture mounting. Cleaning before construction is finished wastes time and money.
Is post-construction cleaning more expensive than regular cleaning?
Yes, typically 2–3 times the cost of a standard deep clean due to the intensive labor, multiple passes, and specialized equipment required.
