Using a level is one of the highest priorities we do when installing gutters.
We always use a level. Period.
You cannot have proper functioning eavestroughs without being level. You cannot eye up the proper slope for eavestroughing. Using a level is a must. A home could be higher at one end and lower at the other end. That being, this is a standard practice at True North.
But it has come to our attention that some installers – from companies I won’t mention – do not use a level. This will lead to bigger issues down the road. Some of the problems we’ve seen include overflowing and holding water . Then, when wintertime comes around and it freezes… then were into all whole other mess. Please, for your sake and mine, make sure your installation is levelled properly!
