Plumbing contractors in Houston, TX average 10–15% net profit margin. The top shops protect margin by qualifying jobs before dispatching — not after.
Houston sits on expansive clay soil that shifts dramatically with wet/dry cycles — the same soil that makes the city prone to flooding also creates constant slab movement that stresses pipes. Slab leaks, foundation-related pipe breaks, and post-flood restoration are significant revenue opportunities unique to the Houston market.

Slab leak detection and repair is Houston plumbing's highest-ticket service: $2,000–$8,000 depending on method, with gross margins of 50–60%. Flood-season restoration work is high-volume but competitive — intake pre-screening helps triage genuine emergencies from lower-priority calls.
