This is how it looks underneath all the wood looks surprisingly good except what you see at the top of the picture were the sill is rotted out only on the side that is sagging.
I have an old garage from around 1900 and it is sinking mainly on one side. But it has no concrete foundation it is just wood flat on the ground.it is a big garage 30feet by 20 feet and 2 story's tall. First thing is how do I get it level then how do I keep it supported. Any help would be great...
