Bought a new 40 gal basic Rheem electric water heater at home depot for $498.00. Note on the heater said: "call before noon to have it installed today". I called the number and got Delta Mechanical. Asked Delta for a price quote and they said the minimum charge woud be $625.00 and that they were the cheapest in town. Then I read the reviews for Delta Mechanical here on Yelp and got scared to try Delta. Called Domco Plumbing in Shingle Springs which has good reviews and they gave me a flat price of $475.00. They were at my house within 2 hours and finished the job in 4 hours and charged the phone quoted price of $475.00. I've had no problems at all with Domco's installation. Delta is definately NOT the cheapest nor a top quality installer and Home Depot cannot be relied on to use contractors that do top quality installs for a low or average price.
