We just had a new mahogony deck built as part of a larger remodeling project. Rather that using lattice as a shirt under the deck, the builder built a shirt out of beadboard. It looks awesome-much nicer than lattice, but we are a little worried about the deck being properly vented underneath. Its pretty much sealed on all sides. Builder says its not a concern, but other builders I've talked to, and things I've read have said that a deck must be properly ventited underneath.

Also interested in people's views on if and how to treat the mahagony.

Yes but more importantly is the vents from the house.

The deck ledger usually goes on the boixer that the underfloor vents are located unless you have a basement.

You didn't mention the size of your deck, but you won't need the same calculation as underfloor venting 1sq ft / 150 sq ft.

I would say you only need enough to get some air flow to the bottom of the joists/decking.

Use the 6x14 underfloor galv. vents put maybe a couple within 3' of the coners, or where they will get the best air access. It should be easy to cut the holes in the skirt & screw them on from the exterior.

If it is 18" off the ground and has spaces between the deck boards, I would not worry about it.

Excellence is its own reward!

I've removed plenty of those over the past 30 years, the deck spacing alone is not enough, you need air to circulate.

With a closed skirts you won't get the movement you need in some seasons.

Timber eating insects LOVE wet wood, and with the new acza treastment not being ground treat percentage under there it'll rot even faster.

Cut a couple of holes & screen it it'll only take a few minutes and you'll be ****her ahead.
