Stang was an excellent company to work with and I highly recommend them. I will be using them again for the (inevitable) future plumbing needs in our old house. Firstly, John the owner was extremely knowledgeable and spent time going through the potential scope and solution to address the deteriorating water service and sewer pipes in our house. This work was a considerable investment (it took a sizeable team multiple days) and John made me very comfortable with what we were about to undertake. The team was punctual, very courteous, and focused on the job. Jason, the team member leading the sewer scope was a pleasure to work with. John and Jason were very communicative through the process and made extra effort to ensure that their activities bothered the neighbors as little as was reasonably possible. I found John and team straightforward and honest which made me comfortable with the work. They absolutely perform to the contract (appropriately so), and I recommend taking the time during the scoping/quote period to ensure that everything you want done is listed: Stang was happy to work through my questions and requested adjustments until the contract was what we all wanted. They offer a good warranty on their work: When the job was complete we noticed a slight seep from a fixture several days after everything was done. John came out right away; as I described what we were seeing while walking him in the front door he diagnosed that the team hadn’t quite tightened up one small part completely and that this would be under the warranty at no cost (He even upgraded an internal part in the fixture while fixing it, which was quite generous of him). They know their business well, they are communicative, they do excellent work, and I have high trust in the work they do.

Great job by Rob at Stang. We had a leak in the ceiling and once the ceiling was opened, Rob found the leak in a pipe running above ductwork. He was able to cut away and repair leaking pipe in a very tough to get to spot. Knowledgeable, efficient, and clean.

The plumber ensured that the drain was running well and even reviewed the pitch of the pipes in the basement. He was very professional and gave excellent reccommenations. I hired them again for more work a couple weeks later and the same high quality, professional standards were present.

After calling to make sure that it was ok, the plumber arrived about 30 minutes before the scheduled appointment. Start-to-finish, the job took about 1.5 hours including cleanup, preparing the invoice, and completing payment by credit card. I am pleased with the service and the cost was in line with other prices I was quoted.

I found the people working for Stang Plumbing to be incredibly honest, and doing the best for their customer seemed to be their top priority. The first time I called them, this past winter, a toilet was so clogged, we couldn't get it working. It was a Saturday evening, and the plumber who called us asked, first, what we needed, and then asked if we really needed it that day. He told us it would cost so much more for him to come out on a weekend, and suggested that, if we could wait until Monday, the price would be much more reasonable. We agreed to wait until Monday, and were actually able to fix it ourselves. That honesty was MOST appreciated. Second issue, this past month, was broken glass stuck in our garbage disposal. Dwayne came out and fixed it, simply and easily in a matter of a few moments. He then told us what we could do if it ever happened again. The price charged was for the full hour, including travel. When I asked him if it was for the full hour, he said they have to charge by the hour, so were there any other issues he could help us with, since he was there and we paid for the full hour. We remembered another toilet that was acting kind of funky lately, so we asked him to look at it. He diagnosed the problem, showed my husband how to fix it if ever happened again, and asked if there was anything else that needed his attention. We SO appreciated his honesty and his desire to give us whatever time we needed. We forgot that our outside faucet was leaking, so we let him go, but rest assured that we will call Stang this week to help us. Good company with good, honest people.

Description of Work
First job, we needed a toilet snaked. Second job, we needed our garbage disposal un-jammed.

They never responded to my message on Angies list. This is the second vendor that has failed to respond or respond in a timely fashion to a request on Angies list. I hate to give anyone a D or E, but I do question the use of Angies list
