Our Services in Missouri

One stop Solutions for all PLUMBING problems

From quick fixes to full installs, we do the work that keeps your water running.

Emergency Plumbing Repairs

Emergency Plumbing Repairs

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.

Water Heater Installation and Replacement

Water Heater Installation and Replacement

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.

Bathroom and Kitchen Rough-In Plumbing

Bathroom and Kitchen Rough-In Plumbing

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.

Faucet Repair and Installation

Faucet Repair and Installation

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.

Leaky Pipe and Fixture Repair

Leaky Pipe and Fixture Repair

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.

Gas Line Installation

Gas Line Installation

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.

Who We Are

A Team Committed to Excellence

Jim Grier

26 Years of Fixing What Others Couldn't

Jim Grier started Express Plumbing in 1999 after working for other companies and seeing how many cut corners or overcharged people who didn't know better. He got his master plumber license and built a business on one idea: show up when you say you will, fix it right, and charge what's fair. Twenty-six years later, that's still how we operate.

We're licensed in St Charles County, St Louis County, and the City of St Louis. We carry full insurance and workers' comp, which protects you if anything goes wrong. Most of our calls come from people who've used us before or heard about us from a neighbor. That tells you something.

Frequently Asked Questions

Got Questions? We’ve Got Answers!

How fast can you get here if it's an emergency?

Most of the time, we're on-site within an hour or two of your call — sometimes faster if we're already in your area. We keep our trucks stocked and ready, so we don't waste time running around for parts. If it's the middle of the night and you've got water everywhere, call (314) 807-8460 and we'll head your way. We're not one of those companies that says "emergency service available" and then makes you wait until morning.

What areas do you cover?

We work all over Lake Saint Louis, Wentzville, O'Fallon, St Peters, Saint Charles, Cottleville, Chesterfield, Maryland Heights, Ballwin, Florissant, and St Louis. If you're nearby and not sure if we cover your area, just call — we'll let you know. We don't charge travel fees, so you're not paying us to drive across three counties.

Are you licensed and insured?

Yes. Jim is a licensed master plumber in St Charles County, St Louis County, and the City of St Louis. We carry full liability insurance and workers' comp, which protects you if something goes wrong on the job. We pull permits when required and our work passes inspection. Don't hire someone who's not licensed — it's not worth the risk when they mess up and you're stuck paying someone else to fix it.

How much does a typical plumbing repair cost?

It depends on what's broken. A simple faucet repair might run you $100–$200. Replacing a water heater is more like $1,200–$2,500 depending on the type and size. We give free estimates, so you'll know the price before we start. If we find something unexpected once we're into the job, we stop and talk to you before we keep going. No surprise bills

Do you do commercial plumbing or just residential?

We do both. We've handled plumbing for office buildings, retail spaces, and small commercial properties around Lake Saint Louis and St Peters. Commercial work usually means bigger systems, more fixtures, and stricter code requirements — we're set up for all of it. If you've got a leaky pipe in your business or need rough-in work for a buildout, give us a call.

Can you help with code violations or rehab projects?

Yes. We've done plenty of rehab work where old plumbing needs brought up to current code. That might mean replacing galvanized pipe, fixing improper venting, or installing backflow preventers. We know what inspectors look for in St Charles County and St Louis County, and we'll make sure your property passes. If you've got a violation notice, we can walk you through what needs fixed.

What if I have more questions?

You can reach us at (314) 807-8460 or email us at [email protected] for more information — we’re always happy to help.
