A 2025 customer described two middle-of-the-night calls for a flooded basement, first from a sump pump failure and later from a broken hot water heater. In 2023, a customer said Hart quoted a mini split system within a couple days and the technicians installed it and cleaned up after they finished. Missed appointments are the concern. A 2023 customer said they waited for a 12-2 window and at 4:12 the office was closed with no one having called or shown up. A 2022 customer said four scheduled appointments over a year for a leak were all a no call / no show. A 2022 customer said Bob Hart looked at a job and promised a quote in a few days, and there was no follow up.
Friendly, quick and efficient service. What else can you ask for.
There was a plumbing emergency, they got me onto a waiting list and later the same day - they showed up with two vans (they were well prepared). The two plumbers diagnosed the issue quickly and had parts to fix the problem on hand. Swift work, clean, and informative future preventative care advice. Thanks again Hart crew!
I’m a local contractor and I’ve been using this company for years. Kevin Hart and his team never drop the ball on anything, they bring the energy every time and complete the mission no matter how challenging. They are efficient on schedule and fair. I will recommend them to anyone.
Isaac and Ben installed my new sink today and corrected the problem with my outdoor water spigot. They were friendly and professional. I will use Hart Plumbing again in the future.
Issac and Ben did an excellent job pinpointing the issue with our water heater and resolved the problem. No more cold showers!
