How to Seal a Gutter

Over time, gutters can wear down and it’s not uncommon to experience a gutter leak. When this happens, you only need a few tools and a little time in order to seal it up and get it back to working correctly. Here, our gutter repair experts tell you how to do it:

What you’ll need to seal a gutter:gutter repair

  • Garden hose
  • Ladder
  • Gutter sealant
  • Caulking knife or spatula
  • Piece of cardboard
  1. First, identify where your leak is coming from.
  2. Standing on the ground, turn on your garden hose and fill up your gutters.
  3. After a minute or so, turn off your hose and inspect the area you think may have a leak.
  4. Once you located it, mark it by placing something on the ground underneath it.
  5. If you cannot locate it, place a ladder against your house and climb up to inspect your gutter more closely.
  6. If your leak is small, you can use gutter sealant to cover the hole from the inside.
  7. Purchase a gutter sealant kits at your local home improvement store.
  8. Next, before you apply your sealant, make sure you remove any debris (leaves, twigs, etc.) from your gutters.
  9. Wipe down the inside area of the gutter where the leak is so that it’s clean and dry.
  10. After that, apply a bead of sealant over your hole and smooth down with a flat caulking knife or spatula.
  11. If there’s a gap in your gutter joint, use a piece of cardboard to force sealant into the open area.
  12. Let the sealant dry completely. You may want to choose a sunny day to repair your gutter so that the sealant has time to cure.
