Shane was the plumbing professional who serviced our home. He was very professionally and knowledgeable. He was very kind and courteous and explained our situation in great detail. A new sump pump was installed, and my family is very happy. I’d also like to recognize the communication that I received as I placed a service ticket online in the middle of the night and by 6:30 AM I received an electronic response via email from the company. A prompt appointment to my liking was set and I most definitely would refer you all again and again. With Love, CJ Brown & Family (New Customer)

I remodeled my laundry room and had to have the plumbing relocated. I have dealt with Mahon plumbing for decades. They always send courteous respectful and very knowledgeable technicians to your home. I have a very busy Schedule and they always show up on the day and the time they promised. They treat your home with respect and the work is always top-notch. When their work is completed they clean up and make sure you're 100% satisfied. I would recommend Mahon plumbing to anyone that needs commercial or residential work done. I promise you will not be disappointed or find a better company.

I hired Mahon Plumbing to replace a 30 year old grinder pump pit at my residence. The office staff kept me informed through the process of parts ordering and scheduling. The morning of the install they sent a large crew with heavy equipment and everyone went to work. The owner committed to being on site and ensuring that everything went smoothly and he stuck to his word. They completed my install and regraded my property in less than a day. I would definitely recommend Mahon Plumbing for residential plumbing projects.
