Faucets, Fixtures and Pipes Repair or Replace
$239
We needed to have the faucet/handles replaced on the sink in our master bathroom. Dave got the job done quickly and efficiently, and cleaned up after his work. He went above and beyond by "fixing" some of the repairs done by a previous homeowner that were not done correctly -- all at a very fair price. I would definitely hire Dave again in the future.

Dave was quick and punctual to get to the job and then was able to complete the task accurately and efficiently. He also was nice to clean up and advise on potential next steps we may need to address separately. Will hire again.

David young (owner of Online Mechanical Svc) signed a contact on 02-13-25 for $5,600 to perform rough in plumbing for a bathroom in the basement. He completed the job and got rough in approval. He told me I dont need final inspection and took full payment on 3/6/25. Later I found that I need final inspection. I finished the job and asked him to call for the final inspection on 4/14/25. He declined to do that because he demanded extra money to finish the job to call for a final inspection. He puts me in a spot where he can squeeze more money from me. He threatened me that he will cancel the permit since I did not paid him extra to finish the job.
Response from On Line Mechanical Service
"This gentleman did the finish work himself. The rules are as follows I am the plumber the permit was in my name. I am required to do the finish work which consists of setting the toilet hooking up the lavatory and tub or shower drain. They took it upon themselves to do this work .I was not aware of this. On my contract the finish work was specified to be done on a time and material basis."

I called Dave to look at our water heater because it was making a loud noise. After looking at the water heater he determined that it didn't need service. Dave is customer focused, he was on time, and he's an honest and nice person. He will be our new plumber going forward.

This guy was fantastic. I had another bid for twice the amount it cost me to have Dave do the job plus the other plumber said I had to order my own parts. If I ever need a plumber again I will hire him
