Mike Brockmann founded the company in the early 1980s. Today his son Josh runs the day-to-day with multiple crews and a team of ten, centrally located and licensed across St. Louis County, St. Louis City, St. Charles County, and Jefferson County.
We've grown enough to handle a 40-unit rough-in and small enough that you'll talk to the same person every time you call.
Most of our work comes by referral — homeowners who've used us, contractors who want a trusted trade partner. Here's what they say.
Joshua Co. is the best plumber hands down in St. Louis. Reliable, honest, and affordable. Most subcontractors leave a mess — Joshua Co. always leaves the job site clean. I have never received a complaint.
I have used Josh and Mike on both commercial and residential projects — new construction and remodel. Always on time, always within budget. I don't even bother to bid them against anyone.
Josh and Mike really listen to what their customer wants. The quality of their workmanship is outstanding. Bids are economical and they don't snowball you with hidden charges. They show up when they say they're coming.
These guys are my favorite contractors ever. I don't actively try to create a plumbing problem in my old Webster Groves home, but when I do have one I always look forward to having Mike and Josh come fix it.
Tell us about the job — new construction, a remodel, a leak that won't quit, or an excavation we need to spec. We'll get back to you the same day, with a real person on the line.
