Recommended Customer Reviews

I am getting my house ready to move and had three issues in my kitchen, and master bath sink stoppers. Sean went above and beyond in helping me buy the proper stoppers and didn't charge me for the hour it took him to buy the right ones. I can't say enough about his professional work and attitude and recommend Sean to anyone in the Truckee area. He is nice and kind and, most of all reliable. Choose him!!

If you need a honest reliable experienced plumber, who has been in business in Truckee for years, I highly recommend Sean.
I had a shower valve issue and didn't know who to call. A co-worker highly suggested I call Sean, she said he was a very nice man. She was right and I am happy I did call. He got right back to me and was able to come over the same day to fix the shower valve. He is professional, knows his business, confirms appointments,shows up on time!.

I needed a plumber to replace a leaky dishwasher air gap and then, days later, a new cartridge for a leaky bathtub faucet. A friend recommended Sean. He responded promptly both times and arrived with everything that was needed. He had both problems fixed quickly. He also showed me what he was doing, so it was a learning experience for me. I hope I don't have to use my new knowledge! I plan to continue to call Sean if I need a plumber! He's awesome!

I was in need of a new toilet and called a few plumbers. The first to call me back was Sean McMahon and he came by the same day. He suggested I buy the toilet myself thereby saving me money. Since the plumbing supply company delivered the toilet for free, it was easy and fast. They were very familiar with Sean and knew exactly what he would recommend. The toilet arrived the next day and Sean came by between larger jobs to install the toilet. I tend to evaluate service people by how well they clean up and how well they care for their equipment. For such a dirty job, I expected my bathroom to need a major cleaning. Not so, Sean is a perfectionist and wait until you see his truck. Spotless. I highly recommend Sean - a good guy all around.

My kitchen plumbing was clogged. Tried to handle myself but no go... called Sean at 4;30 and he indicated he could help the next day at 1:00. He called the next day to confirm, showed up on time and replaced all the terrible tubing under my sink. He was punctual and professional. I would highly recommend calling Sean for any plumbing issues..

I have to write a review because Sean McMahon, really is honorable and extremely knowledgeable. My wife and I are close to having a mother-in-law unit finished at our Truckee home. Over the course of nearly two years that this project has taken, we have had reservations about the HVAC/plumber that our contractor uses. This led me to contact Sean to see if he might come onboard to finish the final phases of plumbing work, in lieu of the HVAC/plumber we had been using for two years. He took one look at photos I emailed him, and he knew the shower valve had been roughed out too far, and there would be problems. He advised me it would be better to have the original plumber face the music and correct the work he had done. Sure enough, the original plumber and our contractor were on site the other day, and they realized the rough plumbing on the shower, through a custom tile job, is all going to have to be redone - by cutting out a closet wall behind the bathroom. It's a bit of a mess. The shower pieces were purchased at Ferguson in Truckee almost two years ago, and the original HVAC/plumber used the components for the rough phase on the valve. Since then, neither he nor the contractor saw any issues - until yesterday. Sean saw problems in one glance at a photo attachment in an email. The guy is super sharp - highly recommend.

Sean is FANTASTIC. Sorted out what i needed really quickly. Also he called out some other issues that I should take care of that I didn't even see. LOVE HIM. Super responsive!

I called Sean and he came over the same day, fixed the leak and was very professional. Would use him again!

Had a leaky faucet that completely drenched the inside of the cabinet below the sink. I spent an hour trying to fix it but to no avail. It was a holiday weekend and I didn't think anyone would be working but I called McMahon anyways. Not only did he answer my call - he talked me through how to fix the problem over the phone! Very honest and trustworthy. If I ever need plumbing service againMcMahon plumbing will be the first plumber I call.

This guy is honest, hardworking and very competent. I accidentally overpaid - Sean called me right away and put a check in the mail the next day. THANKS.
Oh - and he fixed my problem quickly. Better for everyone now that I can take showers again.
