"Good customer service!!!! I called them Christmas eve because our water softener gave up. Chris answered right away and walk me through so we can have our water back. Really appreciate the quick response and the work they’ve done. Very thorough and detailed explaining the issues we had and gave us tips on how to care for the new system they installed. Worked with us also paying for the whole system."

"The technician came on time and, although it took him longer than expected to install the system, he installed it and demonstrated the system for me. The next day, I noticed there was still water on the concrete close to the system but, I figured it was residual water. Apparently the system was leaking. Two days after install I contacted Leaf and advised them that the system was leaking. Early, the next business day, they arrived and repaired the leak and made sure I was happy. My system seems to be working well and I am satisfied."

"Within 5 minutes of requesting a quote, they texted me and then called me. My kitchen sink was stopped up in both drains. I had tried draino but it didn't work. Unfortunately the appointment i had for the next day was canceled but rescheduled for the following day and at the time I needed. Gabriel C was my technician that came over to unclog my drain. He was very polite, professional and clean. He was able to get the water out thru the drain pipe right under the sink. He then pulled the rest of my pipes off and found the clog. He was able to get the gunk out and used his equipment and there were no more clogs down the rest of the pipes. He wore his booties inside and cleaned up after himself. I highly recommend Gabriel C for any of your plumbing needs."
