I had 5 companies come to provide a sewer line replacement quote and Marino had a great price with a contract that clearly laid out the work to be done without any clauses to run up the price like other companies did. Work was done quickly without any issues and they also spent several hours after the sewer line was done making sure the soil was compacted down then put down grass seed and straw. All other companies were only offering to leave a mound of loose dirt. When a small part settled they came back out to fill the area and added more seed and straw.

I had two chief complaints: my shower was leaking and a pipe was leaking in my basement. He was quick to discover the cause of my issues and remedied them efficiently. The bill came out to less than I was anticipating for the breadth of my issues. Hopefully I won't have any more plumbing problems in the future, but if I do I'll use Ace again.

They cut some corners that were not up to code and they installed the expansion tank on the hot side, horizontally, and with no support. When I called in about this they assured me that the tank could be on the hot side no problem. Several other experienced plumbers and the literal instruction manual for the heater all say to never install the tank on the hot side. So I just have to pay someone else to take care of it properly now
