  • Sean McMahon of McMahon's Plumbing has done an outstanding job in responding to my needs for plumbing related problems at my home. I recommend him to anyone needing a plumber within the Truckee area.

  • I have employed Mr. McMahon on a number of occasions in the past for the installation of natural gas lines, repair of leaks in our water system, and the installation of an outside garden water faucet. All projects were completed in an expeditious and efficient manner. I found Sean to be professional and could count on him to get the project done on time. I heartily recommend his work and would not hesitate to hire him again should I have a repair or new project. Sincerely,

  • Over the last year, I have used the services of Sean McMahon twice. Sean came highly recommended by a friend and provided an excellent level of service. He always arrived on time, and provided an accurate estimate for the work that was being requested. All work was completed in a timely manner and his area of work was always picked up at the completion of work. I would highly recommend Sean for any of your residential plumbing needs!

  • Sean answered our calls personally and quickly, arrived on time, and completed the work each time with complete satisfaction and great attention to detail. Two years later and everything still works like new. We wouldn't call anyone else now.

  • I am just a little local client, a homeowner who has small plumbing needs, but Sean has always made me feel like I am the most important client he has when he has done any work at my house. He is a craftsman, and his work is always done on time, done right, and done extremely well. I would recommend him to anyone; he is frankly a wonderful plumber and a pleasure to work with.

  • Delighted to give you our highest recommendation. You have been available on short notice many times over the years, including once on Christmas Eve with a burst bathroom pipe. Digging out an outside water line on another meant a six foot muddy hole. Your services are professional and fairly priced.

  • What a life saver Sean McMahon has been! I've lived in my house on East River Street in Truckee for 30 years. The original four rooms were built between 1898 and 1908. No bathrooms in those days. After many additions, throughout the years, a bathroom and kitchen (with plumbing) existed. In 1982 the pipes broke in the basement. Then the water pressure was so bad because the old pipes were so small. I had had it!

    I have many acquaintances who are plumbers, but none would work on my old house's plumbing. Then someone recommended Sean. For 25 years he's been helping me out. From replacing toilets, running new pipes in the kitchen and bathroom, replacing sewer pipes, replacing hot water heaters, to last fall, running the pressure test for the change from propane to natural gas. Whenever I have needed Sean, he has been right there, getting the job done. Thanks Sean.

  • In January of 2008, I had a pipe freeze up and split in my upstairs bathroom. Luckily, I was able to shut down the water supply to that bathroom without affecting the water supply to the rest of the house. After a week of so my wife asked me to find a plumber to get that bathroom functional again. I called a friend of a friend who was a plumber. He came over right away and spent an hour going through my house explaining how poorly constructed my house was. After an hour he never located the leak and never gave me an estimate for repairs. He then charged me $90.00 for the hour he wasted going through my house and $40.00 for an emergency call. He never followed up with a phone call or stopped by to see if I needed his services.

    I then called Sean McMahon. He came right over and within 5 minutes found the broken pipe and started to work on the problem. He was very fair with his charge (no emergency fee) and had our bathroom up and running within a couple of hours. I have used Sean since and highly recommend him to anyone in need of a professional plumber.

  • As owner operator of Richards Motel I have had need to employ the services of Sean McMahon of McMahon's Plumbing on numerous occasions. He has proved to be qualified, fair and dependable. Always on time if not a little early. Sean obviously takes a lot of pride in his work. He is careful and gets the job done right the first time, with no damage. I have always been very pleased with his work.

  • In February, 2010 we had occasion to hire McMahon's Plumbing, as we had major leaks (water spewing into the air) in a very old house that hadn't been lived in for awhile. Sean McMahon, the owner, actually answered the phone (no recording) and arrived at the house himself within the hour.

    Sean and his crew, after immediately getting the water to stop, thoroughly went through the entire house systematically checking, clearing and correcting all of the plumbing. It was a long process and a dirty one involving a lot of digging and replacing pipes that had been underground for many years. The plumbing "fix" took over a week, but the end result was complete restoration of the plumbing including rebuilt toilets and no dripping faucets.

    McMahon's plumbing was very fair and reasonable in their fee and Sean was able to minimize many costs because of his vast experience. He and his crew were extremely polite and courteous and a pleasure to do business with. We would highly recommend them for all your plumbing needs.

  • Sean McMahon Plumbing has provided service to my home for a number of years and I would recommend his services to anyone in need of a detail oriented professional. He will make sure that the job is done fast, he will offer ways to cut costs, and his estimates are very accurate. He has replaced my water heater, put in gas lines, and fixed broken pipes and with each job, I have been very satisfied. It is nice to find someone I can trust to get the job done at a reasonable price.

  • In twenty plus years as a remodeling contractor I have encountered some tough and unusual plumbing problems but can count on McMahon's to handle them all. One of the difficulties in construction is scheduling, but Sean McMahon will be there when he says he'll be there and completes the job on schedule.

  • My family has a cabin at Donner Lake, and we have relied on McMahon's Plumbing for fifteen plus years. No matter what the issue-emergency repairs, upgrades-Sean has been responsive, reliable, and professional. He communicates clearly about the issue or project and completes the job in a timely manner. As a long-distance homeowner, finding a reliable resource is often a difficult task. Working with Sean has given us peace of mind to know there's someone we can rely on, no matter what the problem.

  • During the bathroom remodel of our Truckee home Sean performed the plumbing work required to relocate all fixtures and complete the installation of an elaborate multi spray head shower system I was so pleased with the service I brought Sean down to my Napa home to perform the plumbing work associated with another complete bathroom remodel, which included removal of the existing galvanized pipe in out 100 year old home and installation of all new copper plumbing. I was extremely pleased with the result of each project: I felt as if Sean was working on his own home in each instance.

    The workmanship, service and professionalism of McMahon's Plumbing is unmatched by any other contractor I have encountered. I price shopped the first project and found Sean very competitive: I did not call any other plumber for the second project, and would not consider using anyone else when I remodel the master bath at my Napa home this summer.

  • Dear Sean:
    Thank you so much for the outstanding job you did on the remodeling of our guest cottage in Nevada City. The new shower, toilet and vanity all work perfectly and look great. The new kitchen looks fabulous! We also want to thank you for all of the times you assisted us over the years while we lived in Truckee. We appreciate your quick response and fair pricing. You have always been on time, professional and dedicated to solving problems quickly.

    We plan on remodeling the kitchen and two bathrooms in the main house next year and we hope you'll be available to help us with that project. We know it's a little far to travel from Truckee to Nevada City but we just don't feel we could find a local plumber who could do the job the way we know you will. Besides, we have a lovely guest cottage you can stay in while you are completing the job! Thanks again for another great job and please feel free to use us as a reference.

  • We have worked with Sean McMahon for more than ten years. He's responsive, reliable, fairly priced, and easy to work with. Sean has worked on three different properties for us, including things as simple as a new toilet or disposal to as complicated as full plumbing for a 1500 square foot addition and kitchen renovation. He treated each job, whether small or large, with the same diligence and dedication that we've come to count on him for. We highly recommend him!

New Construction

  • Sean McMahon has made my life easier and improved my company's reputation over the past 15 years through his work ethics, professionalism and knowledge. Scheduling of custom home construction is difficult as each phase is dependent upon another. Sean's commitment to adhere to the schedule and complete projects within the allotted time is now a welcomed expectation. Custom home building is just that, custom. In custom work not everything is as easy as you would like. Many installations involve unique circumstances and situations not encountered in normal construction. We call upon Sean's experience to help us solve the problems that ultimately arise and keep us on schedule. There is a big difference in getting the job done and getting it done right. All McMahon's Plumbing work is done to a level of quality and detail any professional would appreciate. I know we do! Please feel free to call..

  • Sean McMahon was responsible for all the plumbing in our 7500 square foot rammed earth, concrete floored house. He had to deal with design challenges that required all the rough plumbing to be in place before the concrete floors were poured, and did not allow any plumbing in the outer rammed earth walls.

    The hot water system included a state-of-the-art instant hot water heater and timer-driven recirculation system to insure instant hot water in the further parts of the house such as the kitchen and laundry. Sean is an outstanding plumber. He is knowledgeable and intelligent. He makes good decisions. His advice is worth heading. His work is meticulous and neat. He is easy to work with, reliable and punctual. I have built three homes and worked with a number of plumbers and Sean is far and away the best plumber I have met. We have not had the slightest problem with any of Sean's work and would recommend him to anyone.

  • I have used McMahon's Plumbing for over twenty years for both business and personal projects. One of Sean's most valuable qualities is his ability to foresee and prevent future problems. In the residential construction business, a quality subcontractor is as valuable as a quality employee. That's why McMahon's Plumbing is part of my operation.

  • When you need a plumbing contractor who understands that your job is important, Sean is there. He provides many options for your project to get the right product in the right place, on time and budget. I worked with Sean directly on our project in Serene Lakes and learned a great deal about the plumbing system. From new construction to service work, Sean's decades of detailed plumbing experience are a must for your project. Sean knows the demands that the Tahoe area brings to your plumbing system, so should you. From consulting to contracting, your project is just as important to Sean as it is to you.
