JMG Plumbing runs the plumbing scope on commercial tenant improvements across the Phoenix metro — restroom cores, break rooms, medical and dental fixture packages, underground through trim. We grew out of JMG Contracting, a commercial GC that self-performed its own plumbing for years, so we bid from plans, hit inspection dates, and carry the paperwork without being chased for it.
The full plumbing scope on office, retail, medical, and restaurant tenant improvements — bid from your plan set, coordinated with your other trades, and inspected on schedule. Certificates of insurance and additional insured endorsements available on request.
New and reworked restrooms — carriers, ADA-compliant fixtures, floor drains, and clearances that pass the first time.
Sinks, islands, dishwashers, ice makers, water lines for coffee equipment — the amenity spaces every modern TI includes.
Exam room sinks, lab plumbing, and specialty fixture packages set to the equipment vendor's rough-in specs.
The code-required scope items — mop sinks, drinking fountains, bottle fillers, and water heater compliance.
Saw-cut, trench, and underground DWV through slab, then wall rough and top-out — sequenced so your framing and ceiling trades keep moving.
We schedule and pass our own inspections, show up to GC coordination meetings, and flag conflicts before they cost schedule.
Send the plan set — we return a line-item plumbing bid and flag existing-condition risks up front.
Saw-cut and underground first, then wall rough — coordinated with your framing and electrical.
Tested and inspected on the dates the schedule needs, so ceilings and walls close on time.
Fixtures set, final inspection passed, O&M and warranty docs handed over with the closeout package.
Tenant improvements delivered by the JMG team — plumbing self-performed in-house on projects like these.
From our Peoria shop we run TI plumbing scopes across the Valley:
Yes — send the plan set and we'll return a line-item plumbing bid, typically within a few business days. We flag plan conflicts and existing-condition risks at bid time instead of surprising you with change orders mid-job.
Yes — we handle the plumbing permit and all plumbing inspections for our scope, and we sequence inspection dates with your project schedule so ceilings and walls close on time.
Yes. Much of our TI experience is in occupied buildings — after-hours water shutdowns, coordinated tie-ins, protected paths of travel, and clean daily wrap-ups so neighboring tenants stay open and the property manager stays happy.
Yes — certificates of insurance, additional insured endorsements, conditional and unconditional lien waivers, and clean scheduled billing. We grew out of a commercial GC, so we know exactly what your paperwork stack looks like.
Send us the plans and we'll get back to you within one business day with next steps.
