Before you sign
What to ask a Houston contractor first
- 01
What liability and workers compensation limits does the contractor carry, since most commercial landlords set minimum coverage requirements?
- 02
How does the lease split responsibility between landlord and tenant for this repair, as that determines who authorises the work?
- 03
Which occupancy class and code chapter govern this building, since commercial fixture counts and venting rules differ from residential work?
Before anyone touches a pipe
Verify the licence. It takes two minutes.
- Who licenses the work: Texas State Board of Plumbing Examiners (TSBPE).
- Who pulls the permit: Houston Public Works - Code Enforcement (Houston Permitting Center) — the licensed contractor, never the homeowner.
- What to ask for: the licence number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Commercial in Houston — common questions
How is commercial plumbing different from residential?
Larger pipe sizing, different code classifications, mandated devices like grease interceptors and testable backflow assemblies, documented compliance reporting, and the fact that downtime has a direct revenue cost. Not every residential contractor is set up for it.
How often does a grease trap need service?
It is set by local health regulation and by how fast the trap fills — many jurisdictions require documented service on a fixed interval with retained manifests. Check your local requirement rather than waiting for an odour complaint.
Who handles backflow testing?
A tester with a state or water-purveyor backflow certification, which is a separate credential from a plumbing licence. Most water purveyors require an annual test with the report filed directly with them.
Do I need a permit for plumbing work in Houston?
Permits in Houston are issued by Houston Public Works - Code Enforcement (Houston Permitting Center). As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
Does PlumberTexas charge homeowners anything?
No. PlumberTexas may be compensated by a partner when a homeowner connects with a professional through the site. That never changes what the contractor charges for the job.
Does calling create any obligation to hire?
None. A call or a callback request is a conversation, not a contract. Scope, timing and price are only agreed if you decide to proceed with the professional handling Houston.
Are night and weekend calls handled differently in Houston?
Requests route around the clock, but most contractors price after-hours work differently. Ask for the after-hours rate and a committed arrival window before agreeing to a dispatch.
What information speeds up a commercial callback?
Three things: where the water or problem is showing, whether the supply is shut off, and the property type — slab, crawl space or basement. With those, a pro covering Houston can triage the urgency and bring the right parts.
