Express Plumbing has been serving Wentzville since 1999. We're just down the road in Lake Saint Louis, which puts us about 8 minutes from most Wentzville addresses. That's close enough to matter when you've got a pipe spraying water or a sump pump that quit during a storm. We know the area well — from the older neighborhoods off Highway 61 to the newer developments around Wentzville Parkway. Jim's worked with contractors on new builds out here and fixed plumbing in homes that go back decades. Last spring, we handled three basement rough-ins in one week for families finishing lower levels. When you call a plumber who's been around Wentzville this long, you're getting someone who knows what works and what doesn't in these homes.
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 Real Answer
When you call (314) 807-8460, you're talking to us — not some call center. We ask what's happening and give you a straight answer about whether it needs fixed right now or if it can wait. Since we're just down the road in Lake St Louis, we can usually get to Wentzville addresses same-day, often within the hour for emergencies. We'll tell you when we'll be there, and we show up on time.
We Check It Out and Quote the Job
We arrive with a fully stocked truck and look at what's broken. Whether it's a leaky faucet, a water heater that's done, or a toilet that won't stop running, we explain the problem in plain language and tell you what it'll cost to fix. If you're good with the price, we get started right away. If we find something unexpected, we stop and talk to you before doing extra work.
We Fix It and Make Sure It's Right
Once we start, we don't leave until it's working properly. We use quality parts, we follow code, and we test everything before we're done. Most repairs take a couple hours. Bigger jobs like water heater installs might take half a day. Either way, you'll know it's fixed right, and we clean up the mess before we leave.
