Dallas runs its own water system inside city limits, while Paulding County Water System serves other Dallas-area addresses. Either way, a supply line leaking under the house is a plumbing repair, and inside city limits the City of Dallas issues the permit. Call the number on this page to be connected with a local plumber in Dallas.

What the call looks like
We connect you with an independent plumber who works in Dallas and the surrounding Paulding County area. Let them know whether your bill comes from the City of Dallas or Paulding County Water System, what the meter does with water off and where you see or feel symptoms. On site, the plumber will confirm the leak, check whether it's hot or cold, pressure test and then pinpoint it. You'll hear the options before any floor is opened.
Cost factors
- Time to locate the leak
- Repair through the slab or a reroute
- Flooring at the leak
- Damage that needs drying or repair
- Permits through the city or Paulding County
Dallas conditions
Dallas is the Paulding County seat and a fast-growing exurb whose population roughly tripled between 2000 and 2020. Census survey figures via Point2Homes put the median home at 2002, with about 17% built before 1980. Most homes are newer, so slab leaks usually trace to buried fittings, construction damage or abrasion rather than aged copper.
The City of Dallas runs its own water system, with about 37 miles of distribution lines serving around 2,650 customers in the city service area, buying its water from Paulding County Water System. Paulding County also lists Dallas among the areas it serves, so service depends on the address. For water leaks in city streets or the right-of-way, the city's Water Maintenance line handles them.
Inside city limits, Community Development issues plumbing permits; outside the city, Paulding County does.
Prep list
- Confirm which system bills your water
- Run a meter test with all water off
- Find the main shutoff
- Mark warm or damp areas
- Clear access to the water heater
If the home is new enough, check for builder warranty coverage before work begins.
In a newer Dallas house, many plumbers start by checking whether the leak is on a single branch line. If it is, a short reroute of that branch through a wall can bypass the buried section without opening the slab at all. A direct repair through the floor makes more sense when the leak sits on the main supply run. Either way, the plumber should confirm the location before recommending one. Keep in mind that a slow leak under concrete keeps soaking into the slab and flooring, so it is worth booking a test soon after symptoms appear.
