"I utilized Flo techs, many years ago. They serviced my old hot water heater. They were able to solve the problem at the time. I called them recently for a free estimate. The company does not seem to offer this service any longer."

"I bought a house in Ardsley recently. So, I was looking for an honest and reliable plumber whom I can trust if needed. So, I asked my realtor and she recommended Mr Wilson Taccuri. But He is a dishonest and unreliable plumber. I spoke to two other plumbers over the phone for 3 issues in one of my bathrooms. 1. low water pressure in faucet 2. leaking water around the P trap in the same sink and 3. constant dripping of water thru faucet. They recommended that I replace the faucet with a new one that would take care of everything.. Then I called Mr Wilson Taccuri and told my issues. He came home and fixed the first 2 issues and recommended replacing the faucet to fix the 3rd issues. I wanted to see what he suggest and what he does. Then, I had to buy a new faucet and call another plumber again to replace it. All issues could be fixed in one setting by changing the faucet and changing the valve as those were non-urgent. But he made me call plumber twice and increased the cost of my project."
