What reviewers praise
Water heater replaced within the hour of a same-week follow-up call; Saturday broken toilet fixed within a few hours of calling (themeCounts.fast_response=3, weekend_or_emergency=1)
1 cited review
“We called on a Saturday for a broken toilet and John's plumbing was there within a few hours and did a great job. Then, two days later, our hot water heater failed and began leaking all over the floor. We called John's again and they came right out within an hour and in just a couple of hours we had a brand new hot water heater installed. Their office manager/dispatcher, Anna kept me in the loop and was extremely helpful. We are very impressed with this company and will use them for all our plumbing needs.”
Same-day wax ring diagnosis on a second-floor leak: technician replaced with double wax ring, fair pricing noted for same-day turnaround
1 cited review
“I had a water leak coming from a second-floor toilet, and John's Plumbing and Drain Services was able to send a technician out the same day. Aric was professional, knowledgeable, and efficient. He quickly diagnosed the issue as a failed wax ring and replaced it with a double wax ring to ensure it would last longer. The leak was resolved, and the whole process was smooth and stress-free. Pricing was fair for the quality of service and same-day response. Very satisfied and would definitely recommend them.”
