Water Heater Repair or Service
$2,850
Excellent work completed in less than 24hrs. Wish I?d done my homework for average cost to replace a water heater. $2850 to replace 50 gallon gas water heater seems very steep.

Tankless Water Heater Installation
Yes, I recommend this pro
I hired Posiden to convert my traditional water heater to a new tankless water heater. David was quick to respond, offered great prices, and completed the work when he said he would. Itâ s difficult to find reliable work but Poseidon Plumbing went above and beyond and did a great job. Iâ ll be calling them for all my needs in the future.
