"Recently used Mahon Plumbing for various plumbing needs around my house. As a new homeowner you can be skeptical on what’s behind your walls or in this case pipes. Mahon did an initial sewer line inspection and called them back to swap out toilets and install natural gas in my backyard for a grill and fire table. They were professional, honest, and extremely knowledgeable about all phases of my projects. I would recommend Mahon Plumbing for all of your plumbing needs!"

"They installed a french drain and pump and installed water proofing on the walls.  Initially I thought some of the workers were not really the best, so I called and a manager came out and was very honest and acknowledged their faults and came out and fixed all the issues.  I was very impressed with this, he was very responsible.  They ended up doing a fantastic job in the end."

"Extremely excellent.. The service was good since 2008. They did excellent work. They repair the problem issue by installing a inside french drain and a sump pump. Which correct the problem at the time. The costing was reasonable and except able. And in addition to that courtesy and professional. And very clean after finishing work."

"Once and done waterproofing helped me out with a small annoying leak Iâ  ve had around a pipe. The owner called me right away, came out the next day for an estimate, and fixed the leak the day after. His crew is friendly and courteous and hard working. Explained every step they weâ  re doing. Did such a great job, I had the bury some drain pipes and install a rain water reservoir. Very reasonable pricing and veteranâ  s discount."

"Dan understood our problem did not need trenches and pumps inside our home. Our hill-side home didn't need a sump-pump internal system - drains run to daylight. His gang hand-dug an external trench, laid in perforated drain pipe and silt barriers and drainage gravel. They repaired cracks in the foundation, dried it, applied a drying rubbery material, then installed a dimpled drainage barrier cloth. They graded the earth around the house to aid rainwater runoff. Even re-planted my hasta garden. 2 days, start to finish. We are confident this will succeed."

"I had a flagstone patio that was sinking and uneven due to subsidence. The company removed all the stones, rebuilt the base with a proper slope away from the house, and reinstalled the stones. The price was fair (I had some higher estimates and some lower) and the quality of work was excellent with a good attention to detail. I most appreciated that Lazaro offered a vision for a better patio. My original request was to just replace the stones the way they were, but he made recommendations on how to improve the patio (with the same amount of stones) that led to a much better final project."
