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 21815 Katy Fwy Ste C-103. 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.
