Based in Palm Desert, Riverside County, D G H Development Corporation holds California contractor license #480121, classified B (General Building, C36 Plumbing). License status at the time of compiling this listing: active, with no suspension recorded.
Plumbing contractors hold the C-36 classification, covering repipes, drain and sewer work, gas piping and water heater installation.
Working in the Coachella Valley: Summer highs in the Coachella Valley routinely pass 115°F, and equipment there is sized and specified differently than it would be on the coast.
Before you hire any plumbing contractor: On a water heater replacement, confirm seismic strapping, the expansion tank and the venting are all included. Those are code requirements, not upsells.
License status can change at any time. Confirm license #480121 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
