Four scopes. Twenty-nine years of doing them.
We do not do residential service calls. We do commercial plumbing and the piping scopes next to it, for GCs and owners who need the test to pass the first time.

Commercial plumbing
Complete plumbing scope for commercial new construction and tenant improvement: sanitary and storm underground, water and gas rough, fixtures and trim, backflow and testing, with the same foreman from trench to final.
How we do commercial plumbing
Medical gas
Medical gas piping for hospitals, surgery centers, dental and veterinary: brazed under nitrogen by our own ASSE 6010 installers, verified by a third-party 6020 verifier, documented for the Joint Commission.
How we do medical gas
Hydronic piping
Hydronic piping for central plants and distributed systems: welded, grooved and press, with the hangers, insulation and balancing done right because a hydronic system that is piped wrong is a hydronic system that never works.
How we do hydronic piping
Service and maintenance
Commercial service for the buildings we built and the ones we did not: annual backflow testing, drain and grease line jetting, water heater and fixture work, and a 24-hour line for contract clients.
How we do service and maintenanceBefore you call.
What size projects do you bid?
From about $80k to $4M. Our largest was a hospital at $4.2M. Service work is handled by a separate department.
Do you self-perform medical gas?
Yes, with nine ASSE 6010 installers on payroll. Verification is always by an independent 6020 verifier.
Are you prequalified with hospitals and districts?
Two East Valley hospital systems and four school districts. Limits and EMR are on the capabilities page.
Do you do residential?
No. Commercial only, construction and service.
Send the drawings or describe the building.
A project manager or Carol replies the same business day. Contract clients on the 24-hour line get a plumber, not a service.
