Please don't hire:
My husband and I hired Mr. O to install two standpipes in our basement. He put in two standpipes...then capped them and was paid in full promptly. The first big rain had us bailing water from the standpipe seals for hours during the overnight. I called Mr. O around 11 pm and a worker was present early the next am to confirm the faulty seals around the standpipes. The employee used my hydro cement to fix it. I was NOT told this was not warranty work (later said the PVC pipe was, not the seals). He called and said he would come and talk about a price, never showed, then billed us for $200 to fix his faulty work. Other plumbers have now informed us a capped standpipe is dangerous. When brought to Mr. O's attention, he laughed and said his plumbers had a different opinion.
Overall, we found him to be very arrogant, dishonest and provide subpar work. He also sent a "nice" letter promising legal action if the $200 was not paid. I've never been to court, so the bill was paid.
