Homes built in the 1980s and 1990s around Berkeley Lake and near Duluth Town Green often have copper or galvanized main lines running under slabs. These lines fail when Gwinnett County clay soil expands during heavy summer rains and contracts in mild winters, creating stress points that leak. Slab Leak Pros locates the break with acoustic and camera tools, then decides between spot repair and full reroute based on pipe age and access under the slab.
Trenchless options using pipe bursting or epoxy lining reduce yard damage on properties near Infinite Energy Arena where landscaping is established. We pull permits through Gwinnett County and restore concrete to match existing finishes. Homeowners in Suwanee and Lawrenceville call when water pressure drops suddenly or when a slab leak is suspected from warm spots on the floor.
Hot summers increase water demand and pipe expansion while occasional freezes can split older lines. We carry PEX and copper stock sized for typical Duluth residential feeds and always pressure-test after repair before backfilling. This prevents repeat leaks that commonly appear weeks later when soil settles.
