New company. Colorado plumbing contractor registration is pending, and the full-time responsible master plumber seat is open. How the shop is organized.
01 — Markets
Commercial plumbing for general contractors on the Denver metro and the Colorado Front Range. Mechanical, here, means the piping in those packages: water, waste, and fixtures. Not HVAC, not process piping, and not medical gas.

Owner-operator
Service-disabled Army National Guard veteran and owner of Fathom Mechanical, a certified Service-Disabled Veteran-Owned Small Business. He runs GC relationships from bid through closeout.
Trade
Full-time responsible master. Owns code, field standards, and supervision of the plumbing. Colorado keeps that seat to one contractor at a time. Fathom is hiring for it.

Certified SDVOSB
Fathom’s certification is a tool for the general contractor, on federal, state, and local work across the Denver metro and the Colorado Front Range.
03 — On the job
Look-aheads, trade coordination, and a commercial contact who answers the superintendent. Brandon owns that relationship.
Underground, rough, top-out, and fixture trim on the GC’s sequence. The qualifying master owns means, methods, and code.
Change orders priced against the drawings and the field. Punch is part of the package. We say so when a scope is outside a new shop.
04 — Service area
Based in Littleton. We bid commercial plumbing for general contractors across the Denver metro and the Colorado Front Range, from Colorado Springs through Boulder, Fort Collins, and Greeley. A project outside that corridor is a conversation, not a promise.
Drawings, schedule, and the plumbing scope are enough to start. If the package is outside what a new shop should take, we will say so.
