Frequently Asked Questions

Yes, fully. J.J. Kokesh & Son is fully licensed and insured in the state of Missouri. We are a proud union plumbing company and members of Plumbers Local 562, meaning our plumbers are trained to some of the highest professional standards in the trade. We are also a BBB-accredited business and a multi-year Nextdoor Neighborhood Favorite.

Several things set us apart: 130+ years of continuous St. Louis service, four generations of family craftsmanship, union-trained plumbers, factory certifications from premium brands like TOTO and Moen, and a genuine commitment to treating every customer like family. We show up when we say we will, do the work right, and charge a fair price. Our customers often describe us as the only plumber they’ll ever use, and we don’t take that kind of praise lightly. We strive to keep our work to the highest standard possible.

We are experienced with a wide range of premium plumbing brands: TOTO, Moen, Delta, Brizo, Kohler, Grohe, American Standard, DXV, Native Trails, Rheem, Ruud, Zoeller, Mr. Steam, and ThermaSol. We hold factory authorizations or certifications from several of these brands, including TOTO factory-trained status for NEOREST and WASHLET systems, Moen Pro certification for smart water products, Delta Pro Certified Installer status, Mr. Steam Authorized Installer, and ThermaSol Authorized Service Agent.

Water heaters are one of our specialties. We install and service gas water heaters, electric water heaters, tankless water heaters, hybrid/heat pump water heaters, and propane water heaters throughout the St. Louis area. Not sure which type is right for your home? Our plumbers can walk you through the options based on your household size, usage patterns, and budget.

Absolutely. We specialize in remodeling plumbing, including custom shower installations, freestanding tub installation, bidet and washlet installation, steam shower systems, pot filler installation, kitchen sink and faucet replacement, garbage disposal and dishwasher installation, wet bars, and complete bathroom additions. We also do aging-in-place remodels and basement bathroom additions throughout St. Louis, Chesterfield, Kirkwood, Clayton, and surrounding areas.

Yes. We provide gas pipe repair and installation, including outdoor gas lines for fire pits, outdoor lighting, and outdoor kitchens. Gas line work must be performed by a licensed professional – our experienced team handles these projects safely and to code throughout Greater St. Louis.

We serve both. Kokesh Plumbing has extensive experience with residential and commercial plumbing throughout the Greater St. Louis region. Whether you need repairs at a small office or plumbing for a large commercial facility, our licensed team can handle the job.

It depends on the age of the fixture or system, how frequently the problem recurs, and the cost of ongoing repairs versus replacement. Water heaters typically last 8–12 years; if yours is aging and has needed multiple repairs, replacement is usually more cost-effective long-term. For pipes and drains, a Kokesh plumber can assess the situation and give you an honest recommendation. We offer pipe camera inspections to help identify hidden problems before they become emergencies.

Warning signs include: slow or gurgling drains, low water pressure, discolored or rusty water, unusual sounds like banging or hissing pipes, water stains on walls or ceilings, a running toilet, a water heater that isn’t producing enough hot water, a sudden spike in your water bill, or a sewage smell inside or around your home. If you notice any of these in the St. Louis area, call us at 636-391-1233 for a professional assessment.

A plumbing emergency is any situation that poses an immediate risk of property damage, health hazard, or loss of essential services. Common examples include burst or frozen pipes, major water leaks, sewage backups, no hot water in cold weather, gas line leaks (evacuate and call your gas company first, then call us), a failed sump pump causing flooding, or an overflowing toilet that won’t stop. If you’re unsure whether your situation qualifies, call us and we’ll help you assess it.
