Service was outstanding. Abacus explained what they were going to do and how they were doing it. They allowed me to observe. Successful outcome as well—A+.
The reason for choosing Abacus Plumbing is neatness, courtesy, and professional personnel. Jason's professional workmanship is second to none. Installation of the kitchen sink was perfect. From friendly individuals scheduling appointments to professional plumbers, Abacus is my first choice, and I pass on the good word to others—A+.
I was so impressed. The tech was on time, got it unclogged, and scheduled my camera inspection. The camera tech told me what I knew already—that everything looked great and was fine. I was so happy and will recommend and use them again—A+.
The service was excellent. I'll use Abacus for any future needs.
Abacus reviewed the options for repair versus replacing the main water line leading into the house. The work was completed as described with a minimum of disruption of the water supply. Work area was cleaned up, the ditch closed and the surface restored to its prior condition.
Very good work was done & was on time.
The tech did a very good job, the only thing he did not do was to stick a camera down to see.
Mateo Anaya came to my house on two different occasions. The second time, I asked for him if he was available. He obviously knew his job very well and was very personable and courteous, and always on time (which is mostly unheard of these days). He represents Abacus very well.
The technician was both knowledgeable and communicative.
You guys did a great job.
