Slab Leak Repair and Replacement in Arlington, TX
Need slab leak repair or replacement in Arlington? Arlington grew quickly from the 1960s through the 1980s, and most of that growth was single-story slab houses with copper lines beneath them. We connect you with a local crew that locates the leak before any floor is opened.

Between Dallas and Fort Worth
Arlington is the largest city between Dallas and Fort Worth. It sits on clay-rich ground that moves with moisture, and growth came in waves rather than all at once. The oldest streets are near the center. The great majority of housing, though, was built from the 1960s into the 1990s, in subdivisions laid out on slabs.
That timing puts a large share of Arlington homes in the range where copper under the floor is common, and where polybutylene was used in some subdivisions. A technician confirms what a particular house has.
How the ground works on a slab
When clay takes on water it swells, and when it dries it shrinks and cracks. A slab rides that movement, usually a little at a time. Lines in or beneath the slab are stiff and feel the movement as repeated stress at bends, tees and the points where a pipe passes through a footing. Over decades that can wear a pipe wall until a pinhole opens.
A leak is not a diagnosis about the foundation. If you also see wide cracks or sticking doors, a foundation contractor can assess that. See slab leak or foundation problem.
Say where it is and how long it has been warm.
Copper under 1960s-1980s slabs
Many Arlington houses from the 1960s through the 1980s were built with copper supply lines under the slab. Copper is durable, but decades of movement and water running through it can wear it. The hot side goes first more often than the cold, because heat adds expansion on top of ground movement. A warm spot on the floor, a rising bill and a water heater that runs more than usual are the common first signs.
Houses that have had one leak often have another. See repeat slab leaks.
Subdivisions from the polybutylene era
South and southeast Arlington filled in during the late 1970s through the mid-1990s, the years polybutylene was used in many subdivisions. Houses of that age sometimes have it, and a technician confirms. When it fails, the leak is more often at a fitting than along the pipe. In a house with repeated leaks, repiping may come up. See polybutylene-era homes.

Newer neighborhoods and PEX
Parts of south Arlington, near Mansfield, and more recent infill elsewhere use PEX. PEX flexes with ground movement and has fewer joints under the slab. A leak in a newer home is more likely to be at a fitting or a damaged spot than a general wear problem. The signs and the search steps are the same.
Mature trees in older neighborhoods
Older Arlington neighborhoods have large oaks, pecans and elms close to houses. Roots draw moisture unevenly from the soil, and on a slab house that adds to the movement around the foundation. It is one factor among several and varies by lot.
Rentals and multi-unit properties
Arlington has a large number of rental houses and small multi-unit buildings. A leak in a rental raises a practical question of who calls and who gives access. The page on rental and commercial slab leaks covers access and scheduling in general terms.

How an Arlington leak is located
The technician isolates the hot and cold sides, pressure tests the suspect line and listens along the floor with acoustic equipment. Thermal imaging can show a warm path under tile or wood. These steps narrow the location before any opening is made, though they do not always give an exact point.
What happens after the leak is found
A technician may present spot repair through the slab, rerouting a line above the slab, pipe lining where recommended, or repiping when lines keep failing. What steers the choice is where the leak is, how many have occurred, what the line is made of and what sits above it. No option is always best. Drying is handled by restoration companies and floors by flooring contractors.
Describe the signs you have seen.
Your first move
Turn off every fixture and appliance that uses water, then check whether the meter moves. If it moves, water is escaping somewhere on the Arlington property. See water meter leak check. If water is surfacing, shut off the main if you can reach it safely, keep people and pets away, move valuables and call. Stay clear of outlets and appliances near standing water. If anyone smells gas, leave and call the gas utility and emergency services from outside.

Is it a slab leak?
What tends to show first
- SIGN 01
Warm spot on the floor
In Arlington, a patch that stays warm in shade and with the heating off can follow a hot-water line. A Tarrant County crew can tell you how long the visit is likely to take.
- SIGN 02
Water bill jumped
A bill that rises month after month while the household stays the same in Arlington. A crew serving Arlington can explain what this means for a 1960s-80s house.
- SIGN 03
Running water sound
A faint trickle that stops only when the main is closed on shifting clay soil in Tarrant County.
- SIGN 04
Damp or lifting floor
Wet carpet at an edge, cupped wood or hollow-sounding tile on expansive clay.
- SIGN 05
Water heater never rests
Gas or power use that creeps up with no change in routine for older copper-plumbed houses in Tarrant County.
- SIGN 06
Meter moving, fixtures off
A dial that keeps turning after every tap is closed in mid-century Arlington houses.
Slab leak answers for Arlington
Most houses are single-story slabs built from the 1960s to the 1990s, many with copper under the floor, on clay that moves with moisture. Years of small movement wear lines at bends and joints.
Homes from roughly the late 1970s to the mid-1990s sometimes do. A technician confirms what a particular house has.
Yes. Newer homes with PEX tend to leak at a fitting or a damaged spot.
No. A leak is a plumbing problem. A foundation contractor handles foundation questions.

Roots draw moisture unevenly, which adds to ground movement near a slab. A technician has to locate the leak to say what caused it.
In Arlington, the technician isolates lines, pressure tests, listens with acoustic equipment and may use thermal imaging to narrow the location first.
Sometimes rerouting above the slab avoids it. Whether that is practical depends on the Arlington house.
