Since 2003, RKC Construction in Lakeside has specialized in custom patio covers, sunrooms, and pergolas under CSLB license #841086 (B-General Building) and a second license #680785 for C-61/D-49 glazing and awning fabrication. Alumawood and EliteWood insulated roof panel systems anchor the patio cover lineup, with enclosed Four Seasons Sunroom additions often requiring indoor-outdoor flooring transitions coordinated with Christian Brothers Flooring & Interiors on Woodside Avenue. The company also installs LifeRoom motorized louvered roof systems that integrate retractable screens, LED lighting, and ceiling-fan wiring into a single overhead structure. Each enclosed patio room requires dedicated 120V or 240V circuits for heaters, motorized screens, and smart-home controls — wiring that the crew coordinates with electrical subcontractors including Arce Electric for sub-panel upgrades when existing service capacity falls short. Highest-tier installations include fully enclosed Four Seasons Sunroom rooms with Low-E glass wall systems, R-24 insulated roof panels, and Title 24 energy-compliant HVAC integration for year-round conditioned living space.
