Our 60 Day No-Clog guarantee covers everything possible, except fresh new debris. For example, if you called My Gutter Pro for a gutter cleaning in mid October, when most of your trees haven’t dropped all of their debris yet. You can’t call us back in December and expect us to clean all the new debris. If we are called back for a Service Inspection for a gutter cleaning, and we arrive and it’s apparent that the clogs are due to new fresh debris from after our last service. Then we will still clean the gutter and downspout, but we will also inform you that fresh debris isn’t included in our guarantee and we won’t be able to return for any more fresh debris. We always advise our customers to plan out your gutter cleanings by season. Always try to wait until the end of spring or the end of fall if you can make it. Getting your gutters cleaned at the beginning of either of those seasons, is going to lead to needing another cleaning when the season is over. How Often Should I Clean My Gutters
