Holding CSLB license #1034196 for General Building, H&M Building Services LLC in La Mesa has handled new construction, ADU builds, and full-home renovations from El Cajon Boulevard in La Mesa since 2017. ADU construction in La Mesa's single-family zones requires grading, drainage, and hardscape integration — site-preparation work that runs parallel to the landscape design and patio installation at Botanically Crafted Landscapes. The company's BuildZoom score of 122 ranks in the top one percent of California licensed contractors, with permitted project values averaging approximately $71,700 across new-construction and home-addition scopes. Kitchen and bathroom remodels cover demolition through finish, including custom cabinetry installation, countertop templating, tile setting, and fixture hookup. Window and glass-door replacement on whole-home renovations involves the same structural-header sizing and weatherseal coordination managed by Garland-Fields Glass Co on residential and commercial glazing projects in La Mesa. The firm's highest-complexity scope involves detached ADU construction on hillside lots requiring engineered retaining walls, stepped foundations, and Title 24 energy-compliance documentation for city plan-check approval.
