Founded in 1913 by the Cowling family, Dixieline Lumber and Home Centers supplies lumber, building materials, and home-improvement products from its La Mesa location on Center Drive near Sharp Grossmont Hospital. The Center Drive yard stocks structural lumber, engineered wood products, and framing hardware for the same residential and commercial builds managed by general contractors like Signature Remodels & Construction across La Mesa. Now operating as part of Builders FirstSource, Dixieline runs nine home centers and four distribution facilities across Southern California, employing over 1,000 workers to serve contractors, builders, and homeowners. A dedicated door-and-window design center at the La Mesa branch handles replacement window sales, custom entry-door orders, and installation coordination with in-house crews. Kitchen and bath design services extend the product line into cabinetry, countertop fabrication, and fixture sourcing, complementing the surface-preparation work that Finishing Touch Concrete Coatings, Inc applies to La Mesa garage and patio floors. The La Mesa yard distributes pressure-treated and composite decking systems alongside Feeney cable-rail components, supporting full deck-build packages from ledger-board attachment through railing-post installation.
