The plumber was very professional and friendly. Arrived a little late but at 6:00 pm there is a lot of traffic in Houston. It was no problem for us. Fixed our problem and charged us appropriately. We have been using Abacus for awhile now and have never had a bad experience. The greatest for us was when we came home from vacation and discovered water in our laundry room only to find the hot water heater was leaking. We called them immediately and they came out that same day and got everything replaced. They have replaced a faucet for the ice maker, installed the new hot water heater, replaced a toilet, fixed another toilet, repaired an outside leak, and yesterday repaired our garbage disposal for a minimal fee. They have even called us when an earlier opening came up. My daughter had just recently moved into a brand new house and her bathtub was backing up. She called me and I told her about Abacus. She called them and they went out to her. They told her that the backup was a builder problem and she should not have to pay for it. They also did not charge her for the call. That is honesty and great service. The builder did fix her problem at no charge. I have read some really bad reviews but I can honestly tell you we have never had an issue with them in anyway. We are members of their club and have received some good discounts. We will continue to use them in the future as we have always been treated well.
