These guys are wonderful!! I've been going to Tri-State for 5 years and Joey, Trish, and Patti and the crew are always very helpful in making sure people have the right chemicals they need and they won't try to sell you a bunch of stuff you don't need. They tell you exactly what to do vs. charging you an arm and a leg to make a service call. As long as Tri-State is in business, I will be doing my business there.Thanks guys!!!
