I used that high dollar gutter sealant when i put up my gutters and sure enough they leak at the joints. Everything was brand new and clean but they still leak. What sealant would work better?
Re: Leaking gutters
Here are a few with good reviews:
From gutter Supply.com:
Ruscoe 12-1 and #2 Sealant: For sealing gutter joints, end caps, miters, etc.
Rescue 911 Leak Sealer: A "quick fix" for repairing roof, gutter, and gutter joint leaks.
Titebond Weathermaster: For siding, windows, doors, and vents.
Sounds like any of these could work to keep your gutters from leaking.
