“Frank is the best! We needed last minute plumbing and he was able to get to us asap and fix the problem. While fixing the main problem, another issue arose and he fixed that one on the spot as well! All in all great guy, very responsive and top notch professional service.”
Engineering-level diagnostics: Frank identified a 4" back-pitched waste pipe and gas supply shortfall that the project engineer missed on a large commercial renovation.

What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
1 of 15 reviews (Yelp, 1-star): after a costly full bathroom/kitchen plumbing job, Frank reportedly ignored the low-pressure callback and went uncommunicative — small sample but notable given 15 total reviews.
“Hired him for a huge job, very expensive. New bathroom plumbing and kitchen plumbing. When the job was finished I called him back in because I had very low water pressure and low flow in my entire house. He had the gall to ask for $500 dollars to put in a new faster filter. No thanks, if the brand new plumbing you put in doesn't work it's your job to make it work for the original price. He completely ignored me from then on.”
1 Yelp reviewer (1-star) reports low water pressure left unresolved after expensive new plumbing install — Frank demanded $500 extra for a filter rather than correcting the issue under the original job.
