Granite Shoals Home Services | Plumbing, AC & Electrical on Lake LBJ

Lantz Home Services is your full-service plumbing, AC, and electrical team for Granite Shoals, TX, handling everything from septic-tied drain problems and Hill Country summer cooling to dock wiring and panel upgrades. Whether you live full-time off Phillips Ranch Road, own a waterfront home on one of the residential islands, or keep a weekend lake house near Veterans Park, we install, repair, and maintain the systems that keep your home running. One call covers all three trades. Licensed, insured, and familiar with the rocky soil, shallow granite bedrock, lake-fed water, and brutal summer heat that make home systems here different.

Home systems built for how Granite Shoals actually works

Granite Shoals is an incorporated city on the north shore of Lake LBJ, just west of Marble Falls, and its homes face conditions a standard inland suburb does not. The city operates its own water treatment plant, completed in 2007, drawing surface water from Lake LBJ under an LCRA contract, with a separate well system serving Sherwood Shores 3 in Hoover's Valley. Most homes treat wastewater with septic over rocky ground and shallow granite bedrock. Summers run long and hot, humidity off the lake is constant, and waterfront properties add docks, boathouses, and outdoor power that ordinary homes never deal with. Plumbing, cooling, and electrical all behave differently here, and we built our service around that.

Plumbing

Because most Granite Shoals properties rely on septic rather than central sewer, and sit over rocky, granite-heavy ground, drain problems here are often more than a simple clog. We diagnose the full picture, run line camera inspections, and work within LCRA and county requirements. City water is treated surface water from Lake LBJ, which leaves mineral scale that shortens the life of water heaters, fixtures, and supply lines, so we also handle water heaters, softening and treatment, re-pipes for aging galvanized plumbing, and everyday repairs.

Air conditioning and heating

Hill Country summers are long and punishing, and lake humidity puts extra load on cooling equipment. An undersized or aging system struggles through July and August, and a breakdown during a heat wave is more than an inconvenience. We handle AC repair, full system replacement, and right-sized installs for both modern Hill Country builds and older lake cabins. We service heat pumps and furnaces for the cooler months, perform seasonal tune-ups that catch problems before peak season, and improve airflow and efficiency in homes that were never set up for the heat they now face. For seasonal and weekend homes, we make sure the system is ready before you arrive.

Electrical

Lake-area homes carry electrical demands a typical house does not: dock and boathouse wiring, boat lifts, outdoor and waterfront circuits exposed to moisture, and the grounding and GFCI protection that water proximity makes essential. Older Granite Shoals cabins often run on panels and wiring that were never meant for modern loads. We handle panel upgrades and replacements, whole-home rewires, dedicated circuits for AC and appliances, dock and exterior wiring done to code, GFCI and surge protection, EV charger installs, and generator hookups for the next time the grid drops. Safe, code-compliant work that holds up in a lake environment.

Whole-home and seasonal coverage

Many homes here are weekend places or seasonal lake houses, and an undetected plumbing leak, a dead AC system in the heat, or a wiring fault in an empty house is exactly the kind of problem that gets expensive fast. Because we cover all three trades, we can inspect and protect the whole home in one visit: winterization and freeze protection, pre-arrival system checks, and coordinated work when a project touches more than one system at once.
