What stands out
- A tenth of jobs were declared under $1,670.
- A tenth were declared at $30,000 or more.
What this number is, and is not
- It is the job value a contractor declared on a City of Dallas permit application. It is not an invoice, and the city does not audit it.
- It covers work done under a permit inside the city limits. Jobs done without a permit, and jobs in the suburbs, are not in the file.
- It describes the spread of past jobs. It is not a quote for your home.
- How we picked these permits: Plumbing permits whose description names a sewer line and does not name a water heater.
Before you sign
- Put your quote next to the middle-half range above. If it sits outside, ask what is different about your job.
- Ask whether the price includes pulling the city permit, and ask for the permit number.
- Get the scope in writing: how many feet of pipe, the pipe material, whether the line is under the slab or in the yard, and whether a camera inspection and a final test are included.
- Texas licenses plumbers through the Texas State Board of Plumbing Examiners (TSBPE). Search TSBPE licenses.
