Believe the hype !
I picked Precision due to the rave reviews on HomeStars and my expectations were exceeded. Brandon is a great person to deal with, answers emails promptly and covered any questions I had. They quoted me by looking at my house on Google Streetview (cool), and 24 hours later my eavestrough were completely clean.
Other than the great state of the eavestroughs, verfied by the pictures Brandon's crew took, there is no other evidence they were there at all, they cleaned up after themselves so well.
I'm sure you could get your troughs cleaned for less, but I'm happy to pay the extra to work with true professionals who have the right credentials and insurance to be working 25ft on top of my property.
It's rare to find such as easy company to work with, and i'll definately be using them again.
