I called JG Water Heaters the morning after my 75 gallon gas water heater started leaking. Gregg came out right away and by 5pm his 3-man crew had installed a new tankless one along with all additional per-code gas line and new exhaust. They also changed out the old, faulty water pressure regulator that probably contributed to the leak. Great team. 120% great workmanship, supported by excellent leadership and infrastructure. Pretty perfect. Very highly recommended.
