As a first-time homeowner but someone with a good amount of mechanical skill, I decided to take on the job of installing a garbage disposal by myself. You might guess since I'm writing a review here that things didn't go according to plan, and I decided I needed a professional. To make a long story short, the drain pipe is higher than the output of the garbage disposal, meaning the flow would reverse back into the disposal due to gravity if the plumbing wasn't set up correctly. I could guesstimate the best way to fit things together, but wasn't confident my effort would be leak-free.
Rolo was able to come out on very short notice. In total it was something like 14 hours from logging into Thumbtack on a Saturday night, to hearing the doorbell ring the next morning. He and his helper were both quick, courteous and professional. They had no problems answering my various questions, and were very respectful of me as a plumbing newbie. (Wisely, they did go back over my work with the disposal though!)
For a good price, I got a rock-solid installation under my kitchen sink, and done fast to boot. He even does Venmo! Do yourself a favor and call this man if you need some work done.
