Best Plumbing Upgrade in Boston MA

Frank and his team were recommended to me by several neighbors; I reached out for a quote for the installation of a gas line to add a grill to my deck and he was incredibly responsive. He came to take a look and was incredibly detail-oriented, noting several areas of consideration that other plumbers had not mentioned to me - as a result, we hired them for the job. He arrived right on time and was able to complete the project in short order. Great service, great result - would highly recommend!

DO NOT USE THEM.

I called them for diagnostics service for the water leak from my ceiling. The technician came and stayed for about 1 hour. At the end of the visit, the technician basically couldn't figure out what the problem is. THEY STILL CHARGED $300 FOR IDENTIFYING NOTHING.

After the visit, the technician said he will send me the summary of the visit (that includes pictures, what he looked at during the visit), but they never gave me that information. So I've been calling them OVER A WEEK to get this information but they have been purposefully avoiding my calls.

I got connected to a plumbing contractor through my realtor and he fixed everything for $300. (which is the price I paid for diagnostics service that didn't identify anything and I would have paid over $1000 if I used McMahon Plumbing.)

Great service! Pleasure to work with every time :)

Lawrence F showed up earlier than expected and was very helpful. Best customer service. Also the answering service is awesome, definitely will call back on the future for more services 😀

10/10 perfect!. Came on a Sunday morning and fixed clogged toilet. Would recommend.

They charged me $500 for an estimate that was double what it cost for someone else to do the job...stay away from them!
