Check the License First
In Texas, plumbers must be licensed by the Texas State Board of Plumbing Examiners (TSBPE). There are different license levels: Tradesman, Journeyman, and Master Plumber. A Master Plumber has the most training and experience, and is the only one who can pull permits and run a plumbing business.
Ask for the license number and verify it at tsbpe.texas.gov. If someone can't or won't provide a license number, that's your answer.
Verify Insurance Coverage
A licensed plumber should carry general liability insurance. General liability covers damage to your property during the job. Ask to see a certificate of insurance. Any legitimate plumber will have this ready. If they hesitate, find someone else.
Get Everything in Writing
Before any work begins, you should have a written estimate that includes:
- A description of the problem and proposed solution
- Materials and labor costs broken out separately
- Timeline for completion
- Warranty on parts and labor
- Any conditions that could change the price
"We'll see when we get in there" is not an estimate. Unexpected issues happen. A good plumber tells you upfront what could change the scope and gets your approval before proceeding.
Read Reviews the Right Way
Star ratings matter less than the content of the reviews. Look for specifics: Did the plumber show up on time? Were they clean and professional? Did the final bill match the estimate? How did they handle problems?
Also look at how the company responds to negative reviews. Everyone gets a bad review eventually. What matters is whether they own it and make it right, or get defensive and blame the customer.
Trust Your Gut
A good plumber explains the problem in plain language, gives you options and not just the most expensive one, and answers your questions without making you feel stupid. They don't pressure you into immediate decisions on expensive repairs.
If something feels off, if the urgency seems manufactured, the pricing feels vague, or the plumber seems annoyed by your questions, trust that feeling. There are plenty of honest plumbers in Dallas. Find one who treats you with respect.
