It sounds like it needs to be re-chinked. Not sure what you have on the exterior now, but a coat of new latex chinking would probably help. Call Mike at 866-670-3020 for a rough estimate if you need to contract it..

Mold means moisture. You should contact a local mold remediation company.

It will only rot from the inside out if there is rot in there in the first place. Being on the interior will slow it if there is rot.

Most questions for estimates are not specific enough to answer without further information, thus the call is needed. Last I knew the reason for a web site is to promote your services and products.

Wash first. Any temp above freezing should work.

This is very typical. If you are real concerned then you should have a structural engineer look at them.

Pretty much the same as with a log home. Water is your enemy and keep a good quality latex stain on it.

Wow, not sure what that is. I would let it dry out for the winter and see what’s going on in the spring. Sounds like it’s going to need attention either way.

Could be ventilation issues in the roof or high humidity in the house. Try cleaning with TSP and hot water, but more than likely it will not remove completely. It may need to b sanded to remove.

You should get a flood remediation company to look at it. Also a roofer should look at it for proper ventilation problems.
