Express Plumbing has been serving Cottleville since 1999. We're based in Lake Saint Louis, which puts us about 15 minutes from most Cottleville addresses. That's close enough to get to you fast when a pipe bursts or your water heater quits. We know Cottleville well — from the older homes near Mid Rivers Mall Drive to the newer subdivisions off Highway N. Jim's fixed plumbing in hundreds of Cottleville homes over the years, and he knows the common issues that come up in properties built in different decades. Last month, we handled two basement rough-ins in one week for families finishing their lower levels near Hawk Ridge. When you call a plumber who's been working in Cottleville this long, you're getting someone who knows the area, knows the code, and knows how to get the job done without wasting your time.
From quick fixes to full installs, we do the work that keeps your water running.

Burst pipe? Overflowing toilet? Water spraying from under the sink? We're on our way. Most emergencies happen when you least expect them, and we've seen it all — from frozen pipes in January to sump pumps that quit during a storm. We carry parts on the truck so we can fix most problems same-visit instead of making you wait three days for a callback.

If your shower's running cold or you hear banging sounds from the basement, your water heater's telling you something. We install gas and electric units, and we'll walk you through what size makes sense for your house. Most installs take half a day, and we haul off the old one so you don't have to figure out where it goes.

Building an addition or finishing a basement? We handle the rough-in plumbing before the drywall goes up. That means running supply lines and installing vents so everything's ready when you're set to install fixtures. We work with your contractor's schedule and make sure inspections pass the first time.
A dripping faucet wastes more water than you think — and that sound drives you crazy at night. We fix leaks, replace cartridges, and install new faucets in kitchens and bathrooms. Most repairs take under an hour. If it's shot and needs replacing, we'll tell you straight instead of patching something that'll break again next month.
When heavy rain hits Lake Saint Louis, your sump pump better be working. We test pumps, replace failed units, and install battery backups so you're covered even if the power goes out. A working sump pump is the difference between a dry basement and a mess you'll be cleaning for weeks.

Adding a gas line for a new stove, dryer, or tankless water heater? We run gas pipe to code and test every connection. Gas work isn't something to DIY or trust to someone without a license. We're bonded and insured specifically for this, and we pull permits when they're needed.
Call Us and Get a Straight Answer
When you call (314) 807-8460, you're talking to us directly — not some answering service. We ask what's going on and tell you honestly whether it's something urgent or if it can wait a bit. Since we're just 10 miles away in Lake St Louis, we can usually get to Cottleville same-day, often within the hour for emergencies. We tell you when we'll be there, and we stick to it.
We Figure Out the Problem and Quote the Price
We show up with a fully stocked truck and look at what's broken. Whether it's a leaking pipe, a water heater that's done, or a toilet that won't stop running, we explain what's wrong in plain language and tell you what it'll cost to fix. If you're good with the price, we start right away. If something unexpected pops up once we're into it, we stop and talk to you before doing extra work.
We Fix It and Make Sure It Works
Once we start, we don't leave until the job's done properly. We use quality parts, follow code, and test everything before we're finished. Most repairs take a couple hours. Bigger jobs like water heater installs take half a day. Either way, when we leave, it's fixed right and we've cleaned up after ourselves.
