I am a local Realtor and an investor and In a 50s house that I started remodeling, a problem unfolded and I wanted to change plumbing companies. I was looking for a second opinion, a good diagnosis and I contacted all 3 companies who responded to my Thumbtack request: 1 company never showed up, Right on Time Plumbing's Carlos kept the appointment and I hired him on the spot since he was knowledgeable, he instilled trust in me, he treated me with the to be expected respect (I am a female investor and some contractors show "un-professionalism"), the price was fair AND - despite having a quite full schedule - he could start right away. 3rd company showed up when I just decided to hire Carlos. The entire repair was very involved and it took 1 1/2 days of complete dedication. As far as I can tell, Carlos stayed on schedule, he estimated his time involvement correctly and he cleaned up after he was finished. That is huge! I will be hiring him to finish stage 2 of the remodel which will include installing and connecting all faucets, sinks, toilet before the house is getting listed to be sold. If he keeps up his good work, he will be the plumber I will give all my future work to and who I will refer to to my clients and Realtor peers. Thanks, Carlos.
