FAQs
Everything you need to know about dry space materials.
TimberTech DeckCleaner™ will not damage the DrySpace system, and it can actually be used to clean the surface of DrySpace. Any other cleaners should be verified to be vinyl-safe before using.
Yes. Complete, easy-to-follow instructions come with your DrySpace purchase or you can refer to our Installation Help guide. Installation is easiest with two people. The everyday tools and materials you will need are readily available, and easy to find at your local hardware store.
We do not recommend painting TimberTech DrySpace because of the maintenance issues.
Yes, but it is not ideal. The existing deck boards must be removed before you install the Dryspace or RainEscape System.
In most cases, there is a very little amount of debris that enters the gutter system because it has to be small enough to fit through the decking. Small debris simply passes through the system with water. If your deck is in a leafy area, there may be some build-up. In this case, simply flush out the system with water as needed or at least once a year.
