Sealing your Deck is an Important Part of Protecting your Space

We talk a lot on this blog about outdoor surface cleaning and the renewing your backyard structures. A key component that shouldn’t be overlooked, however, is the final step: sealant. Decks must be properly sealed to stop harsh natural elements from penetrating into the wood.

So what happens if you don’t seal your deck? The number one problem is moisture. As water is absorbed by wood, it leads to rot and decay. Dirt and debris can also build up in the deck’s surface if it isn’t protected in some way.


Most decks need to be sealed every year or two. If you aren’t sure if your deck needs to be sealed, drop some water on its surface and observe. There are two outcomes, beading or no beading. If the water beads up on the surface of the wood, your deck may not need to be sealed yet. If, the wood takes in the water, it’s time to seal.

Sealants are available in a wide variety of colors and finishes, but some are better than others. Make sure to ask what it will look like and how long it will last. At Renew Crew, our protective finish is the finishing touch on our deck cleaning process. Our environmentally friendly finish will seal the wood surfaces’ pores so that water, dirt and grime can’t make its way in and ruin your structure. Additionally, the Renew Crew finish has special polymers that enhance and prolong the beauty of the wood. It even fights off UV rays that can dull or discolor wood decks.

If you have questions regarding sealing your deck, please contact your local Renew Crew.
