Red flag
Overpricing documented: $355 quoted for toilet fill valve that took 10 minutes and a $10-$20 part — competitor fixed same issue for $50 by simply adjusting the existing valve
“they'll do it for $355 (for a part that's $10-$20 and the plumber said that it is very easy for him and he would do it in less than 10 minutes). Didn't go with this overpriced quote, went for another plumber, he just adjusted the valve and fixed the problem for just $50.”

Didn't go with this overpriced quote, went …”

Same situation occured if they offer the air conditioning package, expect your air conditioning to be fixed winter. If I can give no star I will, this company …”

Alex worked cleanly and efficiently and provided us with honest information about our heating unit. Now we are …”
