How do you start a post-construction cleanup business in 2027?

5/9/2026

Honest 5/10 take.

Startup costs: $5k-$20k. HEPA shop vac $400-$800, floor scrubber $1k-$3k, window squeegee/scraper kit, ladders 6ft + 12ft, drywall-dust filter masks (P100), microfiber, pressure washer $400-$1k, trash hauling capability (trailer or truck). Used van or pickup $8k-$20k. LLC + general liability $1k-$2k/yr (higher than residential cleaning � jobsite risk). Workers comp if hiring.

Permits: Business license, contractor cleaning sometimes requires a specialty trade license (varies by state � Florida, California stricter). OSHA 10 cert $80-$150 helps on big sites. Some GCs require certificate of insurance with them as additional insured.

Acquisition: General contractors are 90% of the customer base. Drive new-construction neighborhoods, walk into trailers, ask for the super. Build relationships with 3-5 GCs and you have a calendar. Custom-home builders pay better than tract. Realtors call for final-listing polish. Thumbtack and Angi are residential, weak here. Nextdoor irrelevant. Facebook GC groups help.

Revenue model: Rough/final phases priced separately. $0.30-$0.65/sqft for final clean. 3,500 sqft custom = $1.4k-$2.3k. 2-3 day jobs with a 2-person crew. Rough cleans $0.15-$0.25/sqft.

Year-1: $60k-$140k with one steady GC + sub work. Cashflow is rough � GCs pay net 30-60.
