Slab Leak Detection & Repair in Arlington, TX

If you suspect a leak under your Arlington home, this page covers what to look for, what’s typical for the area, and how to get matched with a licensed local plumber. Fort Worth Leak Detection is a referral and matching service, not a plumbing company.

Why slab leaks are common in Arlington

Arlington’s housing stock spans several decades, and the plumbing under those slabs reflects when each home was built. Older homes may have copper supply lines and cast iron drains that have been in the ground a long time. Many homes from the late 1970s into the 1990s used polybutylene or copper supply lines, and newer homes typically use PEX or copper with PVC drains.

Whatever the pipe, the soil is the common thread. Clay under Arlington slabs swells in wet springs and shrinks during hot, dry summers. Pipes move a little with every cycle, and over years that movement, plus hot-water expansion and contact with concrete, wears through pipe walls and loosens joints.

Signs Arlington homeowners notice first

• A water bill from Arlington Water Utilities that jumps with no change in household use
• A warm patch on tile or hardwood, often in a kitchen, hallway, or bathroom
• A hissing or running-water sound when everything is off
• Damp carpet edges or baseboards away from wet areas
• A water heater that seems to run all the time

Try the simple meter test on our slab leak detection page before calling anyone. If the meter moves with everything off, something is leaking. Closing your home’s main shut-off tells you whether it’s inside the house or in the yard line.

Repair options

Once a leak is pinpointed, Arlington plumbers generally choose between a spot repair through the floor, tunneling from outside, or a reroute through the attic. In older homes with a history of leaks, a whole-house repipe can be the more durable choice. Drain and sewer problems, common with aging cast iron, are a separate issue. See water line and sewer leaks.

Plumbing permits in Arlington are issued by the city, and a licensed plumber normally pulls them for repipes and line replacements. Ask your plumber whether your job needs one.

If water has already caused damage

Slab leak water often spreads under flooring before you see it. If floors or drywall are wet, read water damage after a leak for first steps and insurance basics. If you notice new cracks or sticking doors after a leak, our sister site Fort Worth Foundation Fix covers foundation inspections in Arlington.

Costs and insurance in Arlington

Leak detection is usually a paid service, and national cost guides put it at roughly $150–$400, with typical slab leak repairs around $630–$4,400 including detection (Angi, 2026). Those are national figures, and Arlington quotes depend on access, repair method, flooring, and any water damage. Many homeowners policies help with sudden water damage and the cost of reaching the pipe, but not the pipe itself. Check your policy, and see our FAQ on signs, costs, and insurance.
