As always, impressive work: Jorge Ortiz Duncan Plumbing

Jorge Ortiz has done numerous jobs for us; his work is excellent and his pricing reasonable. This last visit he assembled a very intricate, complex faucet tub shower assembly and, using the available piping material, extended a shower bracket stabilizer in such a way that it looks like it came from the factory as part of the original assembly. His ingenuity is impressive.

responsive, nice guy, fair price after pushback

i had a stopped drain.....Jorge came out that same day , and quoted a price for 2 drains, which was twice the price as for one. I thought that was unfair to double the price, as he was already there. We agreed on a compromise...i am happy with the job and like Jorge.
