Frequently Asked Questions

This is a general guide only and may not address your specific site conditions. If you are not experienced with this type of work, hire a qualified contractor.

For K-Style Systems, how do I know if I need Left or Right End Caps?

Stand facing the building and look at the gutter termination. If the end is on your left, order a Left End Cap. If on your right, order a Right End Cap. This ensures proper appearance from the viewing angle.

Can I use K-Style End Caps on Half Round Gutters?

No. K-Style End Caps have an angular profile that won't fit the curved shape of Half Round Gutters. Each Gutter profile requires its specific End Cap design for proper sealing and appearance.

Do End Caps come with installation hardware?

End Caps are sold separately from fasteners and sealant. In addition to a Gutter End Cap Crimping tool, you can use Pop Rivets or Screws plus high-quality Gutter Sealant for proper installation. This allows you to choose the fastening method that works best for your specific application.

How many End Caps will I need for my project?

Count each gutter run termination. Most residential homes need 4-8 End Caps total (2 per gutter run). Remember to specify Left or Right based on viewing direction for each termination point.

Will End Caps match the color of my Gutters exactly?

Yes. Our End Caps use the same baked-on enamel finish as our Gutters, ensuring perfect color matching. K-Style End Caps are available in all Gutter colors, while Half Round End Caps come in White and Brown.

What fasteners should I use to install End Caps?

Use Gutter End Cap Crimper, and/or Pop Rivets or #8 Hex Screws spaced every 3-4" around the perimeter. Avoid over-tightening to prevent distortion of the End Cap or Gutter profile.

Can I install End Caps myself or do I need a professional?

End Caps can be installed by experienced DIYers with proper tools (i.e. Gutter End Cap Crimper) and sealant. However, professional installation ensures labor and materials warranty coverage and proper sealing, especially for Half Round Systems requiring precise curved fitting.

How long do Aluminum End Caps last?

High-quality aluminum End Caps with baked-on enamel finish typically last 20-30 years with minimal maintenance. The precision-stamped construction and quality materials provide long-term durability with no callbacks.

What happens if I order the wrong size End Cap?

End Caps are profile-specific and cannot be interchanged. 5-Inch End Caps only fit 5-Inch Gutters, and 6-Inch End Caps only fit 6-Inch Gutters. Measure your Gutter width before ordering to ensure proper fit.

Can End Caps be painted if I want to change colors later?

While the factory baked-on finish is designed to last decades, End Caps can be painted if needed. Clean thoroughly, use aluminum-compatible primer, and apply high-quality exterior paint. However, the original finish typically outlasts most paint jobs.
