Who we are
In 1921, James B. Donaghey opened a plumbing repair and contracting business in Mobile, Alabama. The firm grew into commercial and industrial work, added heating in the 1930s and became a regional leader in central air-conditioning in the 1940s. In 1958 it reorganized as James B. Donaghey, Inc. Mechanical Contractors, adding a sheet metal shop to deliver complete mechanical installations.
Our work is grounded in solid engineering methodology, BIM/VDC prefabrication and a self-performing workforce of sheet metal mechanics, pipefitters, plumbers and professional engineers. The result is logical, cost-effective building systems — delivered on schedule, in a safe, professional manner.
Capabilities
From the central plant to the last run of duct, our own crews fabricate and install it — backed by in-house sheet metal and pipe fabrication shops.
Fabrication
Our design-build / design-assist team uses BIM and VDC to prefabricate in our own shops, so owners can count on us to meet the schedule and the budget.
Off-site fabrication cuts field labor, jobsite congestion and rework. Work leaves the shop quality-checked and sequenced for just-in-time delivery.
Markets served
Healthcare, military, industrial, education, gaming and government work — plus commercial buildings, multi-story facilities, hospitality, communications and manufacturing plants across the Gulf Coast. Named 2014 Specialty Contractor of the Year by the Alabama Subcontractors Association.
Safety
Safety is not a policy at James B. Donaghey, Inc. — it is part of the culture. Every employee holds at least OSHA 10-hour training, superintendents run weekly toolbox meetings, and AGC has recognized our safety record 14 consecutive years (2013–2026).
Design-build, design-assist or plan-and-spec — our estimators are ready to help.
