Chimney Chase Wood Water Damage

Chimney chase wood (surrounding brick chimney in attic) has water damage. Its not rotted and is still sound and secure however there are water stains on the wood and it has been taking repeated moisture from leakage over the years.

What would be a good way to refinish the wood or seal it up? I was thinking of painting it with an outdoor stain.... is that a good idea? ANother idea was to sister some 2x material on top of the old?

First find out where the leakage is coming from. After that, you can address the cause.

If it is a stick-built chase, the leaks could be from the exterior cladding (vinyl, stucco, etc.) or from the chimney "cap" at the top of the chase or from any joints/intersections (normal movement or shrinkage) or any improperly flashed joints or laps.

How did you get your view of the inside of the chase?

pics would be helpful

Painting may help but the wood needs to be sound for paint/stain to help.

Hi Dick
What I see is not actually inside the chase... rather, its the framing members that are in plain view around the chimney just before it exits the decking.

Marksr- I think it is sound just because its still very solid and it doesn't not indent at all when poking with a screw driver. Its obvious though that is has taken water over the years.

You want to make sure it's dry before you apply a primer. An oil base primer would be best as it seals better than latex and will prevent any water stains from bleeding thru the finish paint. Latex house paint or solid latex stain is fine for the top coat.

Im probably in the wrong section of the forum. But I was ready to do something with this wood I mention. Do you think its even necessary to paint water stained wood?

Its obviously not for cosmetic reasons since its in an attic. I was thinking to further protect or repair the wood.

It should be fine without paint, after all it sees no weather. Priming and painting would be for aesthetics only.

thx, that is what I was thinking too. Any excuse not to work with paint and stand on ceiling joists while doing it is a good enough for me.
