Donnie is very friendly, helpful and knowledgeable. He helped with my new sprinkler heads. And taught me how to adjust them appropriately. Every year he will winterize the sprinkler system. Definitely, will lend his knowledge on a vast amount of other things he us experienced with. Plumbing, boilers, etc. Very very reasonable with pricing. Ladies & Gentleman he is a must when it comes to all your sprinkler needs.
