Extend the life of your wooden storage shed by caulking seams and corners.

When you first buy a wooden storage building, there is a final step once you’re installation is complete.

Caulk your wooden storage building!

Caulking your storage unit when it is fresh and new will preserve the life of this building and keep it safe for storage.

There are certain areas to pay close attention to when caulking, although you can caulk open space that will let in air or inclement weather. Don’t worry, it’s actually quite easy to caulk a wood shed. Here are our professional tips.






outdoor caulking for woodWhere to Caulk your Wooden Storage Building:

  • Anywhere siding meets. Caulking the seams will make your storage shed waterproof
  • Along the trim
  • Put caulk along the bottom edge of the siding where it overlaps the door
  • Along the edges of the door
  • Underneath the roof where it meets siding
  • Corners
  • Around the windows
  • Around air vents

Attractiveness Tip:

Use paintable/stainable caulk (found at any hardware store like Home Depot, Lowe’s, or Menard’s). If you caulk before painting/staining, your shed will look seamless!

Tips for Application:

  • For latex-based caulk, keep a wet rag or sponge handy to wipe up drips. For silicone-based caulk outline the area with tape if you want your seams to be perfectly straight.
  • Cut the tube hole smaller than you think necessary and test first. It’s easier to make it bigger. Impossible to make it smaller. Start with a small amount, then add more as necessary. Too much caulk can be messy!
  • Don’t try to make your caulk job completely perfect. Water finds its way into the best caulk job, so leave a few air holes for it to dry out.

Caulking your wooden storage building won’t make it last forever, but the shed and the storage items inside will last a lot longer. A little caulk goes a long way!

Should I screw 1″by 6″ over siding seams to prevent warping?

Yes you better caulk these sheds like crazy because they leak like a sieve!! The water is running down the door like a waterfall. Many of the windows leak with one looking like someone has left a faucet on. Two weeks of emails and calls and no response.

Good Morning Jim,

I spoke with your servicing branch and he said he installed an overlay on your roof. Are you still experiencing issues?

I liked that you said that one thing to consider when caulking a surface is to cut the tube open with a small hole and testing it out first, prior to applying it to the actual surface. I would imagine that this method would serve as a proper precaution in order to prevent a mistake during the caulking process. I would be sure to utilize this way of testing before using it on the actual surface so that I could ensure that I will be able to create an accurate application without wasting the product.
