Work Description: Replaced a toilet with a heated bidet seat. It was a rather complicated job and yhe first time they had put in a new kind of seat.

Comments: They came on time and did a fine job. They worked clean and were polite. They gave me the best estimate. I would use them again.

Work Description: repair furnace

Comments: Adam did a great job! Unlike several (5) other contractors he advised we had a good furnace that only needed repair- not replacement- and saves significant dollars. It works great!

Work Description: Plumbing work related to venting and drainage originally needed to deal with strong stench in basement.

Comments: Adam Cowell came when promised to diagnose the problem. We liked his take charge approach and signed on the same day - the work was neat and though complicated, was done in a timely fashion. Highly recommend!

Comments: leaking toilet. Adam came day after Christmas and replaced all the inside 'guts' of the toilet. after he left, there was a new leak from the tank. what impressed me was that he came back with a helper the day i called to say that there was a new problem.. it took them an hour to repair the new problem, and now it's working fine. So what really impressed me is that he came back to fix it again, knowing that he wasn't going to get paid again for the second visit. that's how you get recommendations!

Work Description: Identifying cause of leakage in shower head. We had another local plumber come to the house twice, who tried to fix the leak, but whatever was done did not work. That plumber told us that because the shower was so old it was difficult to find replacement parts. He just happened to have some older fixtures that he was able use parts of them. We were also told that we faced having to redo the shower entirely. Our concerns were hightened when his jobs did not seem to work.

Comments: There was no estimate submitted, Just a telephone call from them. We thought that they were from Setauket but we were informed that they "serviced" the Setauket area. The other three companies submitted to us never made contact. Had difficulty finding info. about Cowel Plumbing, as the web site info. that was furnished was for another company, we were told that they were affiliated with another company and that your web-site may have had the wrong info, to contact them. 1st visit - requested $100. to buy supplies needed to fix leak. Left to go and buy new innards for the water faucets. Two man job? Next day called at about 11:00 am to say that they would arrive cerca noon, arrived closer to 4:00 pm. 2nd visit - forced full blowing of water pressure, reported junk in the pipes that may have caused the leaking. there was no sign of stains from a leak within the inner behind the tiles. Installed new seat and innards. Cost an additonal $200. ($300. total). We wondered if the $300. could have been less if one person arrived to do the job? We were told that if the new settings did not work that they would have to come back and break through the tiles to get to the inner pipe. To date, the leaking has stopped. They both were very pleasant and did a nice job. We would have them back in the future prepared with a listing of questions that they would have to answer before proceeding to do any work. They taught us a good lesson.
