We just bought log home that is 25 years old. Noticing come cracks in the wood that are appearing this winter. We have been using a wood stove as secondary heat. It has D logs that need interior restaining. Should the cracking stop with use of humidifier? Can we fill the cracks when we restain in Spring? What should we use? Also noticed new splotches in wood and some darkening near cracks. Thanks for your help.


The dry heat is definitely not helping for checking (cracking) in the logs. You can fill on the interior but do not fill on the exterior of the home. A humidifier may help little.
