Quality Waterproofing

What Quality Waterproofing does

Quality Waterproofing + Insulation is a privately held home services contractor headquartered in Valley Park, Missouri, serving the St. Louis metro area and surrounding Missouri counties. Founded in 1955, the company is powered by the parent organization Second Mile Service Company and operates within a sister-company ecosystem that includes Gravel Shooters, Kirkwood Fence, and Pure Pest + Lawn. In June 2026, Quality Waterproofing merged with Foam Engineers to form the current entity, adding insulation services to its established waterproofing and foundation repair portfolio.

The company's core offerings span basement waterproofing (interior drainage, sump pumps, dehumidifiers, vapor barriers), exterior waterproofing using Rub-R-Wall membrane systems, foundation repair (carbon fiber crack repair with transferable lifetime warranties, helical and push piering via ECP systems, bowed wall reinforcement, epoxy and polyurethane crack injection), concrete raising (polyjacking and mudjacking), and insulation services (open- and closed-cell spray foam, blown-in insulation, air sealing, energy audits). Diagnostic capability is supported by smoke testing to identify drainage gaps invisible to visual inspection. Revenue is generated primarily through one-time service contracts, supplemented by the $179/year Quality+ Annual Plan (recurring subscription), usage-based dehumidifier rentals at $55/day or $275/week, and a GreenSky financing partnership offering 6- and 12-month no-interest and 84-month 9.99% APR plans.

Go-to-market is sales-led via free inspections and written estimates, with a dedicated residential phone line (314.202.5000) and a separate commercial phone line (314.202.7906) serving home builders, commercial property owners, and municipal infrastructure clients. The customer base is dominated by individual residential homeowners, with commercial and municipal segments representing a smaller, less-disclosed portion of revenue. Marketing relies on an extensive educational blog, YouTube video content, social media presence, and strong review management across Google, BBB, Yelp, Angi, and Houzz, reinforcing a 4.9-star brand reputation built over 70+ years and 70,000+ completed jobs.
