"I tried several companies and Poseidon was the only one who could do a simple toilet repair within a week. Additionally, their policy is to provide a no-cost estimate. Other companies charged for this and did not apply it to the cost if I wee to proceed. The technician arrived on time (after calling as promised to alert me), accurately diagnosed the problem, and fixed it. Charge was slightly below other estimates. I will definitely use Poseidon again if needed."

"Office staff kept me informed regarding appointment time. Plumbers were very informative on how the tankless hot water works and installation details. While plumbers were here they inspected a sewer pit that Seaside installed 8 years ago when I hooked up to public sewer."
