Cristina Robinson

Josh from Mother was fantastic! He arrived on time, wore protective shoe covering, had a red carpet outside my front door, looked at the issue, explained what was wrong and what it would take to fix it, created a temporary fix that day, ordered the remaining needed parts, and set up the next appt. I paid for everything on the first visit so no money needed for the follow up of installation later. Today Josh reached out to let me know he was on the way annd arrived to install the ordered parts and checked and explained everything. I am beyond thrilled. I signed up for a year of membership so I can call them anytime and get help quickly. This is my go to plumbing company now! The folks on the phone were so kind and thorough and Josh is very personable, polite, neat and thorough. Thank you SND for giving me back hot showers!

Josh was amazing! My husband and I really appreciated the time he took to explain everything regarding the tankless water heater, as well as other options! He was very professional and had such a knowledgeable expertise. He didn’t seem in a hurry. He did above what we expected.
