In Santee since 1991, Rayo Wholesale Floorcovering Supply has distributed flooring products and installation supplies to contractors, retailers, and designers from its 140,000-plus-square-foot Woodside Avenue warehouse. The inventory stocks carpet, padding, sheet vinyl, laminate, engineered hardwood, tile, and the full range of carpet-maintenance chemicals and extraction equipment used by cleaning operators such as Stuart Quick Dry Carpet Cleaning elsewhere in East County San Diego. Representing more than 35 manufacturers across 50-plus product lines, the Santee branch is one of seven Rayo locations spanning San Diego County and metropolitan Phoenix. Contractors replacing flooring after termite or pest damage source replacement materials and adhesives through Rayo's trade counter, a supply pipeline that follows the structural clearance and fumigation work performed by Simple Pest Management on Woodside Avenue. The trade showroom displays full-size flooring samples alongside cut-to-length carpet padding in 6-lb, 8-lb, and 10-lb densities, and the warehouse maintains pallet-depth inventory of 6-foot and 12-foot sheet-vinyl rolls, click-lock LVP cartons, and 50-lb bags of modified thin-set mortar for same-day contractor pickup.
