Are your technicians licensed and insured in Texas?
Yes — verified at tsbpe.texas.gov (Master Plumber RMP/MAPGAS #42122) and tdlr.texas.gov (HVAC #TACLA00160134C). Every tech is on our W-2, insured, and background-checked. We don’t use day-labor subcontractors.
What does 24/7 emergency service really mean?
Our office is open Mon–Sat 7am–8pm. Outside those hours, our 24/7 emergency line is answered by a real dispatcher who routes urgent calls — burst pipes, no hot water, sewer backups — to an on-call licensed technician. Most after-hours emergencies in the Katy area are reached within 60–90 minutes.
How much does a diagnostic visit cost?
Flat $49 to drive out and diagnose, regardless of how long the diagnosis takes. If you approve the repair, the $49 comes off the bill. If you don’t, you owe $49 and a written estimate — useful even if you decide to call someone else for a comparison.
Do you serve commercial properties and businesses?
Yes — restaurants, retail, multi-family, offices, and light industrial across the greater Houston area. Backflow prevention, grease trap service, flushometers, commercial HVAC, and 24/7 service contracts are all available.
What areas in Houston do you serve?
Based in Katy at 32126 Hunt Rd Ste 305. Trucks roll out daily to Cinco Ranch, Sugar Land, Richmond, Fulshear, Cypress, Missouri City, west Houston, Brookshire, and Simonton. If you’re a few miles past one of those, call us — we usually still come.
Do you offer financing for large repairs or installations?
Yes — approved financing for jobs over $500. 0% APR promotional plans (must pay off within term), or longer fixed-rate plans up to 84 months. Application takes 3 minutes, decisions usually return before we leave the diagnostic.
How fast can you actually be at my house?
Non-emergency in Katy: usually same-day or next morning. After-hours emergency: 60-90 minutes typical. We give an honest ETA when you call — if we can’t hit it, we say so.
Will you give me a price over the phone?
No — and any plumber who quotes "$XX for a slab leak" sight-unseen is either lowballing you to get in the door, or padding for the worst case. Real diagnosis happens with eyes on the problem. $49 to come look, written estimate before work starts.
Do you charge extra for evenings or weekends?
Standard service hours are Mon–Sat 7am–8pm at no premium. After-hours and Sunday emergency calls have a modest dispatch fee — we'll quote it before dispatching.
What forms of payment do you accept?
Cash, check, Visa/Mastercard/Amex/Discover, and approved financing for jobs over $500. We don’t take crypto or PayPal. We do not require deposits on diagnostics.
