Cross/Sway Beams?

Hello all, this is my first post on the forum, thanks for having me.

My wife and I just bought a townhouse that has a walk down deck. The deck is rather unstable and someone suggested using cross or sway beams to reinforce it. I've tried looking up the how-to on this project but I'm not having any luck. I assume it's an "X" design. Any help would be greatly appreciated.

Welcome to and the Deck forum.

Tell me what you mean when you say "a walk down deck".

Wobbly, I understand. Cross brace the posts under the deck. Parallel to the house as well as perpendicular to the house. That will cure the wobble.

"Cross brace" is just that -- from the bottom of one post to the top of the next with a 1X4 or 2X4. And if you can span 2 or 3 posts, that's all the better.
