Our 1935 home has a concrete block garage, and the doors for both side entry as well as the garage doors themselves, all are made out of wood. All the doors are in good shape, but the frame that makes the connection points from where the garage side door (a regular entry door not a real garage door) itself is supported and where the frame connects to the block has issues. I would like to know how to seal the gap between the wood strip on the side of our door (that makes the doorframe) on the garage and the block that makes up the concrete. It looks like it's a solid concrete block - its not like a cinderblock that you would buy at Home Depot. it would be important because right now we have a quarter to a half inch gap. It looks like the gap was originally filled with some sort of light cement but it could not adapt to the expansion and contraction within the gap. We need to have something I can fill in the gap better. I know when there is concrete to some other material in a big gap sometimes there is a type of very soft, flexible caulking type material that Ive seen, but dont know what it is. Also the wood along the side of the garage door is is of age and has a bit dry rot. It would also be useful to know how the best means of attaching wood to the concrete block would be to shure this or replacement wood up properly. Thanks!
