"Great group of guys. The technicians were great. I believe their names were Mike and Sean. Scott the representative was amazing! From start to finish, he answered every question we had even after hours! ? which is super rare nowadays? Highly recommend for anyone looking for clean, healthy, alkaline water!?"

"when plumber left my house, the drain seemed to work. About a week later, it began to get sluggish again until finally it is just like it was never worked on."

"They did the work, thoroughly explained everything to me, gave me maintenance tips, and recommendations for future projects. Their estimate was lower than the competitor's was. They had everything they needed. They were great."

"job done great"

"Fast communication, easy scheduling, all work was well explained and documented."

"TL;DR: Work remains incomplete. Commitments made by Haven H2O were not fulfilled. We chose this company based on strong reviews and a competitive estimate for replacing our whole?house water softener system. The contract was signed and a deposit paid in December 2025. Installation in January 2026 included materials, equipment, and labor. The brine tank was to be replaced, but Joe did not have it on?hand and said he would return to install it. He also said he would remove the old tank. Neither has occurred. Water softener tanks are not accepted by trash services and are considered hazardous material, creating added disposal burden. Beginning in March 2026, I texted Joe requesting removal of the old tank. ? Mar 4: ?I can get it next week.? ? Mar 12: ?I will be out there next week.? ? Mar 19: ?Trying to get there today or tomorrow.? A voicemail on Mar 30 received no response. Payment was made per the contract, but the work remains incomplete."

"Overestimated the time to complete an 9 hr job by scheduling a 16 hr window (2 guys x 8 hrs) and charged for 16 hrs regardless. I'd imagine they did the same for the materials, 60 feet of duct needed but they quoted 200. Got the job done, but probably twice the price of what it should have been."

"Good / fast job good price"
