Castlewood Plumbing

What Castlewood Plumbing does

Castlewood Plumbing is a family-owned plumbing service contractor headquartered at 1559 Highway 100 in Pacific, Missouri, serving residential and commercial customers across St. Louis County, St. Charles County, and Franklin County. The company was founded in 1993 as Thome Plumbing Co. by Alan Thome and was rebranded to Castlewood Plumbing, now led by his son Matt Thome. It operates under Missouri plumbing license #P8039 and holds a BBB A+ accreditation along with a BusinessRate Top 10 Plumbers 2026 recognition in Franklin County.

The company delivers 23+ distinct plumbing services organized around six core categories: drain services (cleaning, repair, replacement), fixture services, water heater installation and repair, water treatment and softening, piping/repiping and leak detection, and specialty offerings including gas line plumbing, hydro jetting, sump pump services, and camera inspections. Its technology stack centers on conventional plumbing equipment — state-of-the-art video camera inspection rigs for pipe diagnostics and high-pressure hydro jetting systems for clearing grease, roots, and scale — dispatched via fully stocked service vehicles to support same-day appointments and 24/7 emergency response. No proprietary software, AI systems, or technology platform is disclosed.

Revenue is generated primarily through per-job, quote-based service fees, with no publicly disclosed pricing. The business also operates a recurring-revenue layer via the Round Table Membership, which charges an annual fee for priority scheduling, a 10% service discount, and complimentary inspections. Customer acquisition relies on local SEO, an active blog with location-specific pages, promotional coupons, and customer testimonials; customer financing up to $25,000 is offered through a Wisetack partnership to support larger repiping, water heater, and water treatment projects.

Others

• Neighborly (Mr. Rooter parent): Parent company of Mr. Rooter and other home service franchises. Relevant as an indicator of the consolidator model in home services that may eventually acquire regional operators like Castlewood to scale.

Broad incumbents

Competes for the same homeowner customers with similar Punctual-Plumber-type value propositions and franchise-driven local operations.

• Roto-Rooter: Nationally branded plumbing, drain cleaning, and water damage restoration franchise. Directly comparable on drain cleaning, hydro jetting, plumbing repair, and 24/7 emergency service — competes for the same residential and commercial jobs in St. Louis but at a far larger scale with national brand recognition.
• Mr. Rooter Plumbing: Nationwide plumbing franchise under Neighborly offering residential and commercial plumbing services including drain cleaning, water heater, and emergency repair. Operates through locally-owned franchisees that directly compete with Castlewood in the same service categories and customer base.
