Two years later, GutterVac still impresses me. They don't even charge for some tasks (unclogging of a particular gutter as an example) in between main twice yearly trips, now that they know we're long term customers. Thank you Denis, keep up the excellent work.I truly couldn't be happier with the professionalism of Gutter-vac. Both Denis himself and his crew are a joy to work with. This company definitely stands out in the sea of sloppy, inattentive, uncaring, even crooked tradesmen that we have all unfortunately dealt with at one time or another. I'm extremely happy over my perfectly clean windows, gutters and de-mossed and repaired roof. I will definitely call them again!
