Best plumbers
in St. Louis (2026)

J.J. Kokesh & Son has been plumbing St. Louis homes since 1894 — over 130 years, five generations of the same family, and still run by a master plumber: president Joe Kokesh took over from his father Lawrence. Based in Ballwin, Kokesh is a plumbing-only, union shop (Plumbers & Pipefitters Local 562) that handles residential and commercial repairs, remodels, new construction, and 24-hour emergency calls. The company displays its BBB Accredited Business seal on its own site, states that it is fully licensed and insured, publishes its Kehrs Mill Road address and phone in its footer, and was voted a 2025 Nextdoor Neighborhood Favorite. For a metro full of century-old housing stock and cast-iron stacks, that combination — longevity, a union-trained crew, and a real local address — is exactly what this list rewards, and it is why Kokesh leads it.

Tony LaMartina Plumbing has served St. Louis from the city's southwest side since 1982. It is a fourth-generation, family owned and operated company — the LaMartina family counts more than 100 years as master plumbers in St. Louis City — and it does plumbing only: no HVAC or electrical sidelines. That focus shows in the menu. LaMartina repipes whole houses in the materials St. Louis's older homes actually contain (copper, galvanized, clay tile, and cast iron), repairs sewers trenchlessly, and handles hydro jetting, video pipe inspection, and water treatment and filtration alongside everyday repairs and water heaters. Its service model is unusually personal: customers receive their plumber's photo, bio, and a live arrival tracker before every visit, and the company offers a maintenance plan (Tony's Plumbing Protection Plan) and financing. On a list full of good plumbers, LaMartina is the city-based specialist.

J.E. Redington Co. — better known by its working name, Your Home Town Plumber — was founded in Kirkwood in 1929 by longtime resident Jack Redington Sr., and it has been plumbing from the same Leffingwell Avenue base ever since. Redington is one of Kohler's longest-running Authorized Service Providers in St. Louis: it sells the Kohler kitchen and bath lines and is authorized to perform Kohler warranty work. The service menu is as broad as any on this list — new construction, commercial and remodel plumbing, pipe lining and descaling, copper repiping, sewer cleaning, backflow testing, gas line installation, water filtration and softeners, sump pumps, and new water and sewer service installations. Pricing is upfront on most basic services, estimates are free on larger projects, and the guarantee is stated plainly: you will be satisfied with the work. A near-century in one suburb is its own credential.

Maplewood Plumbing & Sewer has been a family shop since 1985, when Ron Oberkrom bought the company; his son Will, who joined full time in 1999, has run it since 2014. From its base on Watson Road at the Maplewood border, the company covers the inner-ring suburbs with drain cleaning, water heaters, gas lines, fixtures, and remodeling — but its real specialty is underground. Maplewood offers trenchless pipelining and LightRay UV pipe repair, and it publishes detailed guidance on the St. Louis area's sewer lateral repair programs, the kind of hyper-local knowledge that matters when a lateral fails. Its plumbers are licensed, bonded, and insured; pricing is upfront; and it backs parts and labor with a one-year warranty. A run of Nextdoor Neighborhood Faves badges (2021–2024) suggests the neighbors agree.

Classic Aire Care's own plumbing pages say it has served the St. Louis area since 1926 — nearly a century — and the company backs the claim with an A+ BBB rating and a 100% satisfaction guarantee published on its site. Plumbing is one division of a larger heating and cooling company, and that scale buys depth: 24/7 emergency service, same-day appointments, and a full menu covering pipe repair and repiping, leak detection, water jetting, sewer line repair and clearing, water heaters including tankless, backflow prevention, gas plumbing, and commercial work. Its plumbing license number (PL12616) is published on its site. Homeowners who want one large, always-available shop — and do not mind that heating and cooling share the marquee — will find one of the deepest benches on this list.

Hoffmann Brothers is the St. Louis metro's best-known multi-trade home services name — a 400-plus-person company working out of Brentwood across heating, cooling, plumbing, electrical, and appliances — and its plumbing division is a real one, not an afterthought. The plumbing menu runs from drain cleaning and everyday repairs to sewer replacement, water line work, water heaters and tankless units, plumbing inspections, sump pumps, water treatment, and commercial plumbing, backed by a home protection plan and emergency availability. The company says it has served Greater St. Louis for more than 40 years; its own site does not state a founding year, so neither do we. Choose Hoffmann when the job is big, the schedule matters, and you want the region's largest residential service operation behind the work.

Merlo Plumbing has been a South County workhorse since 1983. Family-owned and run by president Kenneth Merlo, the company fields union plumbers (Local 562), is fully licensed, bonded, and insured, and keeps a 24/7 on-call line for emergencies. Its homepage counts more than 82,000 completed projects, and its work spans residential and commercial service, sewer and drain work, new construction and contract plumbing, remodels, and water heaters — plus municipal and institutional contract work (it sits on Jefferson County's on-call plumbing vendor list) and a sideline few plumbers can match: Merlo is also a licensed lawn irrigation and fountain contractor. For South County homeowners and property managers alike, it is the quiet, established choice.

Anton's has kept St. Louis homes running since 1979 from its base in Fenton. Family-owned, it is one of the few multi-trade firms on this list where plumbing is a genuine co-lead — it is in the company name — rather than an add-on division. The plumbing side covers service and repairs, drain work, repiping, and water heater repair and replacement in both tank and tankless models, with 24/7 emergency service and upfront pricing as stated themes. (Its technicians also carry NATE certification on the HVAC side.) Southwest County homeowners who want one established company for both the furnace and the water heater — without giving up a real plumbing bench — are Anton's natural customers.

O.J. Laughlin Plumbing is a full-service residential and commercial plumbing and sewer company based in Valley Park. Its plumbers are licensed by St. Louis City and St. Louis County and belong to Plumbers & Pipefitters Local 562, and the company guarantees satisfaction on its work. Sewer service is the deep bench here: cabling, camera inspections, line locates, hydro-flushing and jetting, hydro-excavation, and pumping, alongside water heaters, backflow testing, leak detection, sump pumps, and stack replacement. Laughlin offers same-day emergency service, works with more than 25 general contractors on remodels, and has held Certified 'Green' Contractor status since 2010. It does not publish a founding year, so we do not assign one — its Valley Park roots show in the work instead.

Performance Plumbing is this list's St. Charles County anchor: a family-owned company serving St. Charles and St. Louis County since 1991. It began as commercial plumbing contractors and still carries that rigor — it is licensed, bonded, and insured, and it publishes its license numbers on its own website (St. Louis County P7143, St. Louis City 269, plus its St. Charles licenses), a transparency habit more plumbers should copy. Today the menu covers residential and commercial service, remodeling, water heaters, water treatment, water lines, drain cleaning, and emergency work. The trade-off is geography: the shop sits in Wentzville, at the metro's western edge, though it holds city and county licenses and serves all of St. Louis County.
