The QMS are the best plumbers I've ever used.Get this: they actually: return calls, showup when promised, explain things (and options) to us non-plumbers throughout the work, cleanup after the work is done and are pleasant to work with.They are not the cheapest plumbers out there --- but my experience and I?ve had more than my share including, beyond the clogs, a broken kitchen drain, a broken water main from street, a dead furnace, two creaked water-heaters, a new ductless AC unit installed and dead central air unit--- cheap plumbers cost you too much more later and paying the extra money to properly control the heating, cooling and water in your house is clearly worth.Denise is great plumber. I recommend her to everyone looking for a plumber and they recommend her to others.
