When hiring for old cast iron pipe replacement, trust should be verified — not assumed.
In Texas, licensed plumbers are regulated by the Texas State Board of Plumbing Examiners (TSBPE). Homeowners can search a company’s master plumber’s license number on the Board’s website to confirm that their license is active and in good standing. An inactive or missing license is a major red flag for underground pipe replacement.
Insurance verification matters just as much. General liability insurance is typically tied to a plumbing license, but because it is not required in Texas, workers’ compensation is not publicly listed. Homeowners should ask whether both are carried and understand the difference.
Proper pipe replacement services require licensing because cast iron to PVC conversion involves slope calculations, venting, transitions, and code compliance. These are not excavation tasks — they are plumbing tasks.
Unlicensed work can fail inspection, cause leaks, or require the entire system to be replaced again later. That turns an already significant cast iron pipe replacement cost into an even bigger financial hit.
Verification takes minutes and can prevent years of regret. A professional contractor will welcome these questions and provide clear answers.
Replacing cast iron is too important to leave to assumptions.
Verifying licenses and insurance is simple — and worth it. Reach out to In-House Plumbing Company if you want help confirming the facts.
