Our licensed Master Plumbers handle everything from a dripping faucet to full commercial plumbing installation — all under TX Master Plumber License #41106.
Drain Cleaning in Rockwall, TX
Clogged drains are the single most common plumbing service call in Rockwall, TX. Whether it's a slow bathroom sink in a Heath subdivision home, a grease-packed kitchen line at a restaurant off I-30, or a completely blocked main sewer line in an older neighborhood near Lake Ray Hubbard — Larry's Plumbing diagnoses it right and clears it completely.
Drain cleaning methods we use in Rockwall, TX:
- Flex-shaft drain machines — physically scour blockage material from pipe walls; far more effective than cable snakes for grease and buildup
- Hydro-jetting — 3,000–4,000 PSI water scour for severely scaled lines, grease-heavy kitchen drains, and main sewer lines with root intrusion
- Video camera inspection — for recurring clogs, we scope the line to identify root invasion, pipe bellying, offset joints, or structural damage that simple snaking will never fix
- Mechanical snaking — fast, cost-effective for straightforward blockages in bathroom drains, tubs, and toilets
Rockwall, TX homes built before 1990 often have clay tile sewer lines or cast iron drain pipes. Both materials are highly vulnerable to root intrusion, corrosion, and buildup. If your drain clogs keep coming back every 3–6 months, a camera inspection will show you exactly why — and what the permanent fix is.
2026 drain cleaning cost in Rockwall, TX: Standard drain cleaning runs $150–$300 for a single drain. Hydro-jetting a main sewer line runs $350–$600. Camera inspection is $200–$350 and often waived if you proceed with repair.

Water Heater Repair and Replacement in Rockwall, TX
Water heater problems have recognizable symptoms: no hot water, lukewarm water that runs out in 10 minutes, rust-colored water at the hot tap, popping or rumbling from the tank during heating cycles, or water pooling at the base of the unit.
Rockwall, TX has moderately hard water — mineral hardness that accelerates sediment buildup inside water heater tanks. That sediment layer insulates the heating element, forces longer run cycles, and shortens effective tank life. Annual tank flushing is the single highest-ROI maintenance task for Rockwall water heater owners.
Our Rockwall, TX water heater services include:
- Standard tank water heater repair (all major brands: Rheem, Bradford White, AO Smith, State)
- 40, 50, and 75-gallon tank replacement — most jobs completed in 2–3 hours, old unit hauled away
- Tankless water heater installation and service (Rinnai, Navien, Noritz)
- Expansion tank installation — required by Rockwall code for closed plumbing systems
- Anode rod inspection and replacement
- Annual tank flush and maintenance
- Pressure relief valve replacement
2026 water heater costs in Rockwall, TX: Tank replacement (40-gal) runs $950–$1,400 installed. Tankless installation runs $1,800–$3,200 depending on gas line work required. Repair (thermostat, element, valve) runs $200–$500.
If your water heater is over 10 years old and showing symptoms, the honest answer is often replacement — not repair. We'll tell you which makes financial sense before any work begins.

Leak Detection in Rockwall, TX
Rockwall, TX sits on expansive clay soil — soil that swells when wet and contracts severely during summer drought. That constant movement stresses underground water supply lines, making slab leaks unusually common in Rockwall-area homes compared to most of DFW.
Warning signs of a slab leak or hidden pipe leak in your Rockwall home:
- Water bill increased $50–$150/month without explanation
- Sound of water running inside walls or under floors when everything is turned off
- Warm or hot spots on your floor (hot water line leak beneath the slab)
- New cracks appearing in drywall, tile, or hardwood
- Water meter dial moving when all fixtures are off
- Mold or mildew smell in a specific room with no visible water source
Larry's Plumbing uses non-destructive leak detection — electronic listening equipment, thermal imaging, and pressure testing — to pinpoint the exact leak location before any cutting or demolition begins. We don't open walls to go searching.
Once located, we present three repair options with honest cost guidance: direct access (open only at the leak point), above-slab reroute (new line through attic or walls, bypassing the damaged section entirely), or full repipe (for homes with widespread pipe deterioration).

Slab Leak Repair in Rockwall, TX
Slab leaks are a specific subset of leak detection that deserve their own section — because Rockwall, TX has a significantly elevated slab leak rate due to that expansive clay soil. Homes in neighborhoods like The Ridge, Chandler Creek, Dalton Ranch, and the older lakeside communities near Lake Ray Hubbard see slab leak calls regularly.
A slab leak left unrepaired causes structural concrete damage, mold growth inside walls, and water bill spikes that compound every month. The average Rockwall slab leak repair runs $2,500–$5,500 depending on the repair method chosen. Catching it early — before the water migrates across the slab — is the difference between a 1-day repair and a multi-week remediation project.
