Express Plumbing has been serving Saint John since 1999. We're based in Lake Saint Louis, which puts us about 40–42 minutes from most Saint John addresses depending on traffic. Jim's a licensed master plumber in St Louis County and he's worked on homes and small commercial properties all over Saint John. We've handled emergency repairs, water heater replacements, sump pump installations, and bathroom remodels across this area. When you've been working in Saint John this long, you know the common issues in the area's homes, you understand what local properties need, and you know how to get the job done efficiently.
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 and Get Honest Answers
When you call (314) 807-8460, you're talking directly to us. We ask what's happening and tell you honestly whether it needs immediate attention or if it can wait. Since we're about 35 miles away in Lake St Louis, we can usually get to Saint John same-day — often within an hour or two for emergencies. We'll tell you when to expect us, and we show up on time.
We Figure Out the Problem and Quote It
We arrive with a fully stocked truck and diagnose what's wrong. Whether it's a leaking pipe, a failed water heater, or a sump pump that quit, 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. If something unexpected comes up, we stop and talk to you before doing extra work.
We Fix It and Make Sure It Works
Once we start working, we don't leave until it'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 replacements take half a day. When we're done, it's fixed right and we clean up before we leave.
