Thornmill Plumbing serves Round Rock and the northern Austin suburbs with licensed, upfront-priced plumbing — drains, water heaters, leaks and repipes. You get a text when we are on the way, a price before we start, and a dry floor when we leave.
Homes across Round Rock have their own needs when it comes to plumbing — the local climate, how homes here are built, and everyday wear all play a part. Thornmill Plumbing knows Round Rock and handles every plumbing job the right way for this area.

Repair or replace, tank or tankless, sized for your home and installed to code the same day.
Electronic detection that finds the leak before the jackhammer comes anywhere near your slab.
Whole-home repipes in PEX with drywall patched — most homes done in two to three days.
Faucets, toilets, disposals and shower valves installed clean, caulked, and leak-tested.
Thornmill Plumbing is a family-run shop out of Round Rock. We built the company on two habits: quoting the job before the wrench comes out, and treating slab leaks with the urgency they deserve in this soil. Our techs are licensed, background-checked, and drive fully stocked trucks so most jobs finish in one visit.
No trip fee inside our service area — you approve a written price before any work begins.
Possibly — shut off fixtures, watch the meter, and call us; the detection visit is cheaper than a month of that bill.
