Water Heater Installation & Repair

Waking up to no hot water is one of the most disruptive plumbing problems a homeowner can face. Whether your water heater is leaking, making strange noises, running out of hot water too quickly, or simply aging past its useful life, Kokesh Plumbing can help. We install and service all water heater types, including traditional tank units, tankless on-demand systems, and hybrid heat pump models, for both gas and electric setups. Homeowners often ask us whether a tankless water heater is worth the investment. In many cases, yes! They deliver endless hot water and lower energy bills over time. If you’re not sure whether to repair or replace your current unit, we’ll give you an honest answer based on your system’s age, condition, and your household’s needs.

Toilet Repair & Maintenance

If your toilet is running constantly, won’t flush properly, is leaking at the base, or keeps clogging, these aren’t problems you should ignore. A running toilet alone can waste hundreds of gallons of water per day, silently driving up your water bill. Kokesh Plumbing diagnoses and repairs all common toilet problems, including faulty flappers, worn fill valves, weak flush pressure, and cracked components, and of course full toilet replacements when repair no longer makes sense. Thinking about upgrading to a comfort-height, dual-flush, or high-efficiency toilet? We can help you choose a model that fits your bathroom, your habits, and your budget.

Kitchen Faucet Installation & Repair

A dripping kitchen faucet, a handle that’s hard to turn, or a sprayer that’s lost its pressure are all signs it’s time to call a plumber. Left unaddressed, even a slow drip can waste thousands of gallons of water annually. Kokesh Plumbing installs and repairs all kitchen faucet styles — from standard single-handle fixtures to high-arc pull-down and commercial-style models. If you’re remodeling your kitchen or simply want to swap out an outdated faucet for something that performs better and looks great, we make the process simple. We work with all major brands and can help you find a fixture that balances quality and value.

Sump Pump Repair & Installation

If your sump pump stops working during a heavy rainstorm, the results can be devastating. Homeowners often don’t think about their sump pump until it fails, and by then, water is already entering the basement. Kokesh Plumbing installs, repairs, and replaces sump pump systems, and can add smart environmental monitoring that sends you an alert if your pump fails or water levels rise unexpectedly. If your sump pump is running constantly, making unusual noises, or is more than seven to ten years old, it’s worth having it inspected before the next big storm tests it.

Garbage Disposal Installation

A garbage disposal that hums but won’t spin, leaks under the sink, or simply stops working is a common kitchen frustration. Kokesh Plumbing installs and replaces garbage disposals of all sizes and brands, ensuring proper drain alignment and leak-free connections from day one. If you’ve never had a disposal and want one added, we handle that as well, including all necessary drain modifications. Wondering which disposal is best for your household? We’ll point you toward a model that matches your usage without overselling you on horsepower you don’t need.

Shower Installation & Repair

A shower that drips when it’s off, delivers inconsistent water temperature, or has lost water pressure is telling you something is wrong. Kokesh Plumbing handles all shower repairs, including shower valve replacement, cartridge repair, and pressure balancing fixes. We also handle full shower installations from standard setups to custom builds featuring rain heads, body sprays, and handheld fixtures. If you’re renovating a bathroom and want a shower that genuinely feels like a luxury experience, our team has the expertise to make it happen correctly and without costly surprises.

Water Softener Installation

If you’re noticing white scale buildup on your faucets, spots on your dishes, dry or itchy skin after showering, or appliances that seem to wear out faster than they should, hard water is likely the culprit. Kokesh Plumbing installs whole-home water softening systems that treat water at the point it enters your house, protecting every pipe, fixture, and appliance downstream. Homeowners who invest in water softeners often report noticeable improvements in water quality almost immediately. We’ll assess your water hardness and recommend a system sized correctly for your household.

Gas Line Installation & Repair

Gas line work is not a DIY project; it requires a licensed plumber with the training and tools to do it safely and to code. Whether you’re adding a gas line for a new outdoor kitchen, a fire pit, a gas range, or a whole-home generator, Kokesh Plumbing handles the installation from start to finish. We also repair damaged or aging gas lines throughout the home. If you smell gas, notice a higher-than-usual gas bill, or have dead vegetation above where your gas line runs, call us immediately. Gas leaks are emergencies that require professional attention right away.

Whole House Leak Detection

Most home water leaks aren’t visible, but they’re happening inside walls, under slabs, or behind appliances, silently causing mold, structural damage, and skyrocketing water bills. Homeowners frequently search for answers to questions like “why is my water bill so high” or “how do I know if I have a hidden water leak”, and the answer often lies in a whole-home leak detection system. Kokesh Plumbing installs smart water monitoring systems that track your usage in real time and automatically shut off your water supply the moment a leak is detected. It’s one of the most effective ways to protect your home from the kind of water damage that insurance doesn’t always fully cover.

Bathroom Faucet Installation & Repair

A bathroom faucet that drips, runs slow, wobbles at the base, or has visible corrosion isn’t just an eyesore, it’s also wasting water and signaling that something needs attention. Kokesh Plumbing installs and repairs all bathroom faucet types, including single-hole, centerset, widespread, and wall-mounted configurations. If you’re updating a bathroom vanity or simply replacing a faucet that’s past its prime, we make the process easy. We work with fixtures across all price points and can help you find an option that looks great, performs reliably, and holds up over time.

Drain Cleaning

A slow drain is easy to ignore — until it stops draining altogether. Whether it’s a kitchen sink that’s backing up, a bathroom drain that’s sluggish, a shower that’s pooling water around your feet, or a main sewer line that’s affecting multiple fixtures at once, Kokesh Plumbing gets to the root of the problem and clears it completely. Homeowners often try store-bought chemical drain cleaners first, but these rarely solve the underlying issue and can actually damage older pipes over time. If you’re dealing with a drain that clogs repeatedly, gurgling sounds coming from your pipes, or unpleasant odors rising from your drains, those are signs of a blockage that needs professional attention. We use professional-grade equipment, including hydrojetting, to clear obstructions quickly and thoroughly, and can inspect your drain lines with a camera if we suspect a deeper issue like tree root intrusion, pipe scaling, or a collapsed line. Don’t wait until a slow drain becomes a sewage backup. Kokesh Plumbing resolves drain problems at the source, not just the surface!

What’s Going On With St. Louis Lateral Lines?

If you live in a St. Louis home built before 1970, your sewer lateral line — the pipe connecting your home to the public sewer main — is likely made of aging clay that may be cracking, shifting, or clogged with tree roots. Warning signs include slow drains, sewage odors, wet spots in the yard, or basement backups. The good news is that St. Louis County’s Sewer Lateral Repair Program (SLRP) can help cover repair costs for the portion of pipe under the public right-of-way, though anything under your private property is your responsibility. The process starts with hiring a licensed St. Louis plumber to camera-inspect the line to assess the repair situation, then submitting the findings through a “Residential Sewer Lateral Repair Application” to the County to qualify for assistance. The sooner you act, the better, these pipes don’t improve with age. Contact us today to get your lateral line replacement process started.

What plumbing issues are most common in Clayton’s older homes?

Clayton’s residential neighborhoods are among the most architecturally historic in St. Louis County, with many homes dating to the 1920s, 1930s, and 1940s. In homes of that era, we commonly see aging galvanized supply lines, cast iron drain stacks, outdated water heater configurations, and worn fixture hardware that benefits from professional attention. We’re experienced working in historic and pre-war properties and take care to respect the character of the homes we work in.

Can you handle plumbing in Clayton’s high-rise condominiums and apartment buildings?

Yes. Clayton’s downtown and surrounding neighborhoods include a significant number of multi-unit residential and commercial buildings, and Kokesh Plumbing has the experience and licensing to handle plumbing in both residential and commercial settings, ranging from individual unit repairs to larger building systems.

Do you handle kitchen and bathroom remodeling plumbing in Clayton?

Absolutely. Many Clayton homeowners invest in high-end kitchen and bathroom remodels, and we work alongside contractors and designers throughout the process, from rough-in plumbing to final fixture installation. We are also certified installers for several premium fixture brands including Toto, Moen, and Delta, which are popular choices in Clayton’s market.
