  • 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.

  • We are licensed real estate agents who deal almost exclusively with bank owned properties through our employer, Truckee Mountain Properties, in both California and Nevada. Whenever we have need for a plumber, especially in the Truckee/Tahoe area, we work exclusively with Sean McMahon. He is responsive to our calls and needs, punctual, always meets his deadlines. His pricing is fair, his personality is outgoing and friendly and his work is thorough and complete. We feel extremely comfortable working with Sean McMahon and are fortunate to have him as "our" plumber.

  • 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.
