What Western Magnesite Inc does

Western Magnesite Inc (legal entity R&G Development Corporation, dba Western Magnesite Company) is a Southern California specialty contractor founded in 1961 and headquartered in North Hollywood. The company installs and repairs waterproof deck coatings, concrete surfacing, stair systems, planters, and garage floor coatings for residential and commercial properties, with primary service to property management companies, production home builders (including DR Horton and Toll Brothers), HOAs, and individual homeowners in the Los Angeles and San Diego markets. Following Bernard Fainstein's 1998 acquisition, the business pivoted from magnesite repair into an industry leader serving top Southern California home builders.

The company's core technology is a portfolio of fiberglass-based waterproofing systems installed by certified in-house crews. Desert Crete is a 6-7 layer complete system applied from plywood up and carries a 1-hour fire rating with ICBO Evaluation Service approval; Desert Flex is a 4-5 layer overlay system applied over existing concrete, magnesite, or elastomeric surfaces. Complementary offerings include polyurethane/epoxy garage floor coatings (TerrazzoStone), stamped concrete overlays, and steel-framed precast stair systems with City of Los Angeles pre-approved standard plans. The legacy magnesite system was discontinued in 2018 after the sole Southern California supplier ceased operations.

Western Magnesite operates a relationship-driven, sales-led go-to-market: estimator visits to properties, a toll-free number (1-800 WEST MAG), and a website quote form generate project-based revenue, with an 8-year conditional warranty and 20-30 month scheduled resealing programs providing recurring service touchpoints. Marketing is primarily referral-driven (90% retention through repeat business and referrals), supplemented by content marketing, apartment-industry publications, and memberships in the Community Associations Institute and Apartment Owners Association. The company is privately held, employs 11-50 people, and has not raised external funding.
