Sean, Jake and Mike are an exceptional crew!!! Highly recommend. Quality work every time.
Had coastal out yesterday… hours to hookup a toilet, bathroom and kitchen sink… nothing major… two drains and one wax ring! he was here for hours! After he left, I happen to look out the window to discover he turned my hose on full blast and left it that way… I would never recommend or use them again…
EXCEPTIONAL communication & service!! I texted Sean Bogni at 7:30 AM for an emergency water heater issue. Within 5 minutes he had Jake & Mike diagnosing & replacing it before 11 a.m. Clearly why Coastline Plumbing & Heating is an elite team. Thank you!!!
Professional, efficient and courteous
Can’t say enough good things about Sean and Coastline. Came home from a vaca to no heat in my house on a Friday night. Calked Coastline and got a call back in less than 30 minutes. Sean was at our house at 8 AM the next morning and fixed the problem. Great experience
