Although these gutters are only a year old, they weren't installed right! The corners were sealed with latex caulking. This is a problem because the caulking doesn't bond well to the aluminum and these corners leak. If not repaired soon, the fascia (wood behind the gutters) will start to rot out. If you need gutters, make sure you go with a pro. Call Rainy Day Roofing & Exteriors at (866) 596-2030 or go to http://www.rainydayservices.com for more information.
