How It Works

Technicians diagnose water entry points (cracks, hydrostatic pressure, grading), then install solutions: interior drain tile systems, sump pumps, wall anchors, vapor barriers, or exterior waterproof membranes. Average job ticket: $5,000–$12,000. Many operators add annual maintenance plans to build recurring revenue. Leads come from Google Local Services Ads, HomeAdvisor, and insurance adjuster referrals.
