A fellow handyman on this site told me he was capable to plumbing even tho he was not certified. I let him do work on my place and have had nothing but problems. Leaks, floods, drips, etc... I contacted Mark at Blue Frog specifically because the guy above told me not to. I couldn't be happier. This man is kind, honest and really, REALLY knows his stuff. All at a vey reasonable rate. In addition, he offered my elderly neighbour a discounted seniors rate. I am VERY appreciative and would HIGHLY recommend.
