We’re best known for fast response times and our ability to provide focused solutions to drain & sewer problems. From sinks, toilets, and tubs to main drains, roof drains, storm drains, and anything else that carries water, we’ve got you covered. We also offer grease trap cleaning services and planned preventative maintenance.
"Extremely customer service experience. The representative I dealt with was not only unhelpful but also came across. As both judgmental and lacking professionalism when I asked clear questions about pricing I received vague misleading answers. They scheduled an appointment that I had agreed upon for one o'clock pm but no one show up or call. Instead I received a text for 1 o'clock pm.; When I called to let them know The situation and the pricing they have changed their answer from 1 -3pm and told me that there was a fee that would be applied. When I asked a follow up question the Rep. hung up on me. The overall behavior was unprofessional and extremely biased based on demographic that they choose not to served. I would expect more transparency, respect and communication."

"Only rating 1 because it doesn't go lower. Had a new unit installed end of Sept 24. First time power goes out on 11/5, no electricity. When tri state sells you a product, they pitch their amazing customer service with all these guarnatees of knowing when your unit is out before you know and having someone there within 24 hours etc. Well, the first call we make we are told it will be the end of Nov to get someone out to look at it. 3 weeks. Nobody shows up. Then we get a call that says "your appointment on Dec 12 has been canceled and the earliest we can get to you is Jan 16th. This is 2.5 months wait to get service to fix a nearly $20k unit, that is upcharged because of the excellent service. You can't get anyone to answer your call. you wait on hold for 20 minutes, then have to leave a voicemail in which you will not get called back. Based on my experience, find someone else and pay less. Even if the service is bad, which it can't be worse than this, you save money! @kohler"
