Working out of Rancho Mirage in Riverside County, Mills Custom Services is licensed by the California State License Board under #811832, classification B (General Building). License status at the time of compiling this listing: active, with no suspension recorded.
General contractors hold the license that lets one company take responsibility for a project involving two or more unrelated trades — a room addition, a whole-house remodel, a garage conversion, a rebuild after fire or water damage. The general pulls the permit, schedules the subcontractors, and answers for the finished result.
Working in the Coachella Valley: Blowing sand and long periods of intense sun are hard on exterior finishes, seals and mechanical equipment, and they shorten maintenance intervals noticeably.
Before you hire any general contractor: On a project of any size, ask for the payment schedule in writing before work starts. California caps the down payment on home improvement contracts at $1,000 or 10% of the contract price, whichever is less — progress payments after that should track completed work, not the calendar.
License status can change at any time. Confirm license #811832 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
