Workers are very professional, on time, respectful of my home, i.e wearing shoe covers, efficient and leaves the house with everything intact . As I wait for my next appt and can review my last two visits I question the cost for the work done in my tub, somewhat excessive. Curtis has been checking my systems for several years and just this year I am being told my tankless hot water heater was not installed to code! Two years ago a water softener was attached to this not to code system yet nothing was said then. I need someone to contact me and explain this issue. I need to know I am not just a gullible costumer!
