GEI Plumbing Services Houston

Ask for the plumber’s Texas license or registration and verify it with the Texas State Board of Plumbing Examiners (TSBPE) or the appropriate local permitting office. Confirm the license type (e.g., journeyman or master) matches the work. Request a current certificate of insurance showing general liability coverage and, if applicable, workers’ compensation or proof of exemption. Make sure the name on the license and insurance matches the contracting business and ask for references or recent job photos.

Major plumbing work — new installations, water heater replacement (in many cases), repipes, sewer or sewer-line repairs, and changes to the drainage, water, or gas systems — typically requires a permit and inspection from the City of Houston or your local municipality. Minor repairs like replacing a faucet or fixing a leak often do not. Reputable contractors will tell you whether a permit is required and will usually pull the permit and schedule inspections; confirm in writing who is responsible for permits so there are no surprises at closing or during resale.

Get a written, itemized estimate that separates labor, parts, permit fees and any emergency or overtime charges. Some contractors quote flat rates for common jobs; others bill hourly—confirm the rate, how time is tracked, and whether materials are mark‑ups. Ask about written warranties for labor (workmanship) and whether parts carry manufacturer warranties; get warranty terms in writing. Because Houston’s climate and local water quality can affect pipes and fixtures, ask about recommended materials, potential corrosion issues, and whether preventive options (backflow devices, sump pumps, or sewer backflow protection) are appropriate for your property.
