The dirty services industry is recession-resistant and growing. People always need junk removed, drains unclogged, mold remediated, and properties cleaned up. The combined market for residential and commercial dirty services exceeds $50 billion annually in the US.
The most profitable segments by margin: crime scene/biohazard cleanup (40-60% margins), mold remediation (35-50%), power washing (50-65%), and junk removal (40-60%). The highest revenue segments: demolition ($15B market), waste management ($80B+), and environmental remediation ($15B).
What makes this industry attractive for entrepreneurs: low barriers to entry for many services, strong repeat business from commercial accounts, recession-resistant demand, and limited competition in most local markets. The biggest players are national franchises (1-800-GOT-JUNK, ServPro, ServiceMaster), but independent operators dominate local markets.
Pricing dirty services requires understanding three variables: your costs (fixed + variable), your market (what competitors charge), and your value (certifications, speed, reliability).
Junk Removal: Charge by truckload, not hourly. 1/4 truck: $150-$250. 1/2 truck: $250-$400. Full truck: $400-$800. Heavy items (pianos, hot tubs) command premium pricing ($200-$500 additional). Always include disposal fees.
Power Washing: Residential: $0.15-$0.40/sq ft for flat surfaces, $0.20-$0.50/sq ft for vertical surfaces. Target $100-$200/hour effective rate. Offer package deals: "whole house" pricing for siding + driveway + patio.
Biohazard/Crime Scene: Never charge hourly — charge by scope. Small bathroom: $2,000-$5,000. Single room: $5,000-$10,000. Full house: $10,000-$30,000. Insurance pays in most cases, so price for full remediation value.
OSHA doesn't have a specific "dirty services" standard, but multiple standards apply depending on your services. The big ones: Bloodborne Pathogens (1910.1030) for any biohazard work, Respiratory Protection (1910.134) for mold and chemical exposure, Confined Spaces (1910.146) for septic and drain work, and Fall Protection (1926.501) for any work above 6 feet.
The cost of non-compliance is severe. OSHA serious violations carry penalties up to $16,131 each. Willful violations: up to $161,323. Repeat violations: up to $161,323. Beyond fines, an OSHA citation can destroy your reputation and make it impossible to get insurance or win commercial contracts.
Build safety into your business from day one. Create written safety plans, train every employee before they touch a job site, document everything, and invest in proper PPE. The upfront cost of compliance is a fraction of what a single OSHA violation — or worse, a worker injury — will cost you.
