The plumber San Antonio has called since 1954

Notice something in the reviews below: Rudy, Tino, Nathan, Adolph, Michael, Toby — when people review Ajax, they name their plumber. That only happens when the plumber was worth remembering.
“Had a emergency called this other Plumbing co, said they were to busy to fit us in. Meanwhile the pipe to the main line had split open… these guys from Ajax plumbing came to our rescue. Not even half hour went by they were here… Thanks to Adolph who was very professional kept us informed as to what was going on…”
“Nathan came out to my place in San Antonio to fix my slow-draining bathroom sink and bathtub. He checked everything, gave me a clear quote, and explained that if anything unexpected came up, he would talk it over with me before moving forward. I appreciated knowing the price upfront…”
“AJAX was the first to respond to our request for a quote. They were also the only team we ended up needing to hear from…”
“Ajax was very professional and polite. The service tech Tino that came out explained everything to me in great detail…”
“…Ajax plumbing came out and they were awesome. Even helped quickly fix a clogged drain in my upstairs bathroom for no charge. Respectful, quick and explained everything in detail. Highly recommend.”

Who we are
A family shop, three generations in
Noe Salinas built Ajax into the kind of plumbing company that stays put: founded in 1954 and family-owned and operated ever since, with the Salinas family still running the shop today. The Little Plumber on the van has been a West Side fixture longer than most of the businesses around it.
“We have been in business 69 years — same address and location, and same phone number.”
— Ajax Plumbing, in the company's own words
Licensed plumbing company — Responsible Master Plumber License #15641, the same number painted on the van. All work guaranteed.
