We have used Mark for years for all of our plumbing and gas needs. He has always been polite, courteous, punctual and RELIABLE! Very rare to come across these days. No matter if it's day, night or a weekend, Mark will try to fit it in where he can, wether it's an emergency or not! Most recently, my elderly parents furnace conked out on them. I advised them to call Mark to see what the issue was. He diagnosed it very quickly and had it up and running in no time, where as another company they called, could not come until the next day. He even went over the next day to make sure it was running as it should be. If anyone is looking for a reliable plumber or gas fitter, Mark is your man!!
