JMG Plumbing is the plumbing partner built for contractors. We run rough-in and trim for residential bathroom and kitchen remodelers, and full plumbing scope on small-to-mid commercial tenant improvements — bid fast, show up on schedule, and pass inspection the first time. Backed by the JMG Contracting team.
We're a working sub, not a call-center plumber. Our customers are the contractors who build — and who need a plumbing partner that protects their schedule and their reputation.
Bathroom and kitchen remodelers who need dependable rough-in and trim without babysitting the plumber. We work to your production schedule, keep the job site clean, and coordinate directly with your PM or lead carpenter.
Remodel Plumbing →General contractors delivering small-to-mid tenant improvements — office, retail, restaurant, and medical suites. We bid from your plans, handle permits and inspections on our scope, and hit your lease-commencement dates.
TI Plumbing →Suite turns, fixture replacements, repairs, and tenant-requested plumbing changes across commercial properties — scheduled around your tenants, documented for your files.
Full remodel and tenant-improvement plumbing scope — from slab to trim — plus the service work that keeps buildings running.
Tub-to-shower conversions, relocated drains and supplies, valve set-outs, freestanding tub rough-ins, and finish trim. We rough to your tile layout and come back for trim when you're ready.
Learn More →Sink and island relocations, pot fillers, ice maker and dishwasher lines, disposals, and gas connections for ranges — coordinated with your cabinet and countertop schedule so trim never holds up the punch list.
Learn More →Break rooms, restroom cores, mop sinks, drinking fountains, medical and restaurant fixture packages — full plumbing scope on tenant improvements, from underground to final inspection.
Learn More →Faucets, toilets, shower systems, sinks, and specialty fixtures set clean and leak-tested. We handle owner-supplied fixtures without drama and flag missing parts before they cost you a trip charge.
Whole-home and partial repipes, DWV corrections uncovered mid-remodel, and re-routes for wall removals and floor-plan changes — priced fast so a surprise behind the drywall doesn't stall your job.
Tank and tankless water heater installs and swaps, shut-off and angle-stop replacements, leak repairs, and punch-list plumbing on occupied properties.
Every remodeler has a plumber horror story — the no-show, the failed inspection, the change order ambush. Our whole business is built on not being that guy.
Send plans or walk us through the space and you get a written scope and number you can drop straight into your proposal — with exclusions spelled out so there are no surprises later.
Rough-in lands when your framing is ready, trim lands when your finishes are in. We confirm the day before, show up when we said, and tell you early if anything moves.
Pressure tests documented, code items handled before the inspector walks the job. Our goal on every project is a first-pass green tag on your rough and final.
COIs, W-9s, lien waivers with every invoice, and clean draw billing that matches your schedule of values. Your bookkeeper will never chase us.
Floor protection, daily cleanup, and respectful crews — whether it's a family living through a remodel or a tenant working next to your TI.
When the wall opens up and the DWV is a mess, you get photos, options, and a price — in writing, before we touch it. No invoice surprises at the end of the job.
JMG Plumbing grew out of JMG Contracting, a Phoenix-metro general contractor that has self-performed plumbing on its own residential remodels and commercial tenant improvements for years. We know exactly what a remodeler or GC needs from a plumbing sub — because we build as one.
That builder's DNA shows up on your job: we read plans, we understand sequencing, we respect other trades' work, and we know a blown plumbing date ripples through your tile setter, your cabinet installer, and your client's move-in. So we don't blow dates.
We serve residential remodel contractors, commercial general contractors, and property managers across the Phoenix metro. Licensed, bonded, and insured in Arizona — certificates of insurance and additional insured endorsements available on request.
Tell us about the job — or send plans — and we'll get back to you within one business day.
