"Polite enough, but not very responsive with follow-up texts and scheduling. Inconsiderate of damages done to the home while completing his tasks (unnecessary demo in the basement, severe scuffing of hardwood floors during radiator repairs, etc). Left old pipes and trash from a job for the homeowner to dispose of. Installed new garbage disposal WITHOUT power cord; small appliance is not able to be used and drain now clogged."

"Fixed it. They wanted $340 for one shut off valve to a fixture but came down when questioned (this was much higher than I have seen in the past). Friendly plumber and quick service. They came out the morning after my request."

"Router Guy is great! I used them previously for a large job with a leaking pipe through the wall, where they had to go into the wall to fix it. This time, I had clogged plumbing. They were very responsive. Eric showed up timely. He was very professional and friendly. The fixed the clog no problem (the plumber I had the day before said they couldn't unclog it and it would be 20 grand to fix!) He was great, and rooter guy seems to be consistently good. I only bothered getting another plumber because I couldn't remember who did my last work - that taught me a lesson! Rooter guy is now saved in my phone :) thanks for your help, your professionalism, kindness, and honesty. "
