O E M Windows & Doors operates out of Wildomar in Riverside County and carries CSLB license #1138658, classification B — General Building. At the time this listing was compiled, the license was active with no suspension recorded.
A general contractor’s work is coordination as much as construction: framing, roofing, electrical, plumbing, drywall, finish carpentry and inspection sign-off all have to happen in sequence, and the general is the one holding that sequence together. Typical jobs run from a single-room addition to a full structural remodel.
Working in southwest Riverside County: This corridor grew quickly, so the housing stock ranges from 1970s tract homes to work finished last year — and the two need very different approaches.
Before you hire any general contractor: Ask who is actually pulling the permit. If a contractor asks the homeowner to pull an owner-builder permit on a job this size, the homeowner takes on the liability, and that is a reason to slow down rather than sign.
License status can change at any time. Confirm license #1138658 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
