We use Alcoa Seamless Gutters which are produced by a special machine with no seams.  Connections of seamless gutters are done only on the inside and outside corners, and downspout outlets.

• All gutters are installed using hidden screw hangers spaced every 16 inches apart and 4 inches from the ends
• Levels are used to ensure gutters have proper pitch
• Box mitres for corner transitions
• Premium gutter sealant is used to seal end caps and mitres
• Stainless steel screws are used, most companies use zinc plated, these rust shortly after installation
• Downspouts are installed using hidden clips as opposed to leader straps
• 2-story downspouts require a minimum of 3 clips, most companies use only 2
