Commercial Tenant Improvement Plumbing in Phoenix

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.

What We Handle

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.

Restroom Cores & ADA Fixtures

New and reworked restrooms — carriers, ADA-compliant fixtures, floor drains, and clearances that pass the first time.

Break Rooms & Coffee Bars

Sinks, islands, dishwashers, ice makers, water lines for coffee equipment — the amenity spaces every modern TI includes.

Medical & Dental Packages

Exam room sinks, lab plumbing, and specialty fixture packages set to the equipment vendor's rough-in specs.

Mop Sinks & Drinking Fountains

The code-required scope items — mop sinks, drinking fountains, bottle fillers, and water heater compliance.

Underground & Rough-In

Saw-cut, trench, and underground DWV through slab, then wall rough and top-out — sequenced so your framing and ceiling trades keep moving.

Inspections & GC Coordination

We schedule and pass our own inspections, show up to GC coordination meetings, and flag conflicts before they cost schedule.

How It Works

Our Process

01

Plan Review & Bid

Send the plan set — we return a line-item plumbing bid and flag existing-condition risks up front.

02

Underground & Rough

Saw-cut and underground first, then wall rough — coordinated with your framing and electrical.

03

Top-Out & Inspections

Tested and inspected on the dates the schedule needs, so ceilings and walls close on time.

04

Trim & Final

Fixtures set, final inspection passed, O&M and warranty docs handed over with the closeout package.

Questions

Frequently Asked

Can you bid the plumbing scope from plans?

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.

Do you handle plumbing permits and inspections on TI work?

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.

Can you work in occupied buildings or after hours?

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.

Do you provide COIs and lien waivers?

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.
