"I called Gash Plumbing and they were here the next day. The guy was professional and worked really hard to clean and empty our septic tank. He went well above just placing a hose and pumping out. I will use them again."

"Working for two years to get a septic tank replacement. Previous plumber incorrectly installed it and several plumbers kept giving me large quotes. O'Conor's gave me not only the lowest quote, but did not add extra work to replace tanks such as laterals."

"They provided a time frame of when they would be able to perform my septic tank clean out. Their service person called when they were on the way. He easily completed his job task with a pleasant easy going professional attitude. I’ll be calling them back the next time I need my septic tank serviced for sure."

"Jeremy was very prompt for the initial estimate and took the time to explain why one of the options was much better than the other. He scheduled the job quickly and showed up a few minutes early that day. He finished the work well within the estimated time frame. It was quality work done right the first time. I have marked JCM as a favorite for our plumbing needs."

"Mac Wilson is my new go-to plumbing connection, Their prices and service are excellent. They provided a prompt free evaluation and estimate, didn't try to intimidate us with scare tactics on the repair needed or sell us products or service we didn't need. When we called with an additional technical question we were immediately transferred to the owner who provided the answer immediately. The other estimates we received were all over the place and one of which was 4x the cost AND would've left us with damaged walls we would have had to repair at additional cost with someone else afterwards. We will definitely use Mac Wilson for our water tank replacement next year."

"Everyone at the Leaky Cellar was fantastic.  We called after a steady rain Thursday night had turned our small problem of a basement crack into something that felt like a waterfall coming out of our walls. 
They were able to fit us in after 5 the very next day which was good because it proceeded to rain all day Sunday and I was out of town for the weekend. 
The fact that they were able to come out the same day we called and were able to fix the problem would on its own be enough.  But pair that with a very fair price, Lonnie being absolutely wonderful for my wife to deal with and what you end up with is a very satisfied customer.
Well done!
