0:15Decide it before you dig
Don Ross on deciding the structure, subfloor and subfloor heat of a freezer building before anyone digs.
Dan Ross on the two places doors fail, rotting jambs and adjusting sills that freeze, and what D.W. Ross builds instead.
Dan Ross, D.W. Ross Company. 0:48.
One of the most common problems with doors is the jambs rot out from the bottom up, and we use all composite jambs, composite brick molds, so that doesn't happen. The other problem is like a lot of doors have sills that are either fixed or they have an adjusting sill where you turn a screw to adjust that door.
The problem with it is when those doors sit on like a brick stool or concrete, the water wicks up through the bottom of the sill, and those screws then freeze and become, you know, they're not adjustable anymore. So, we've gone to self-adjusting sills, which very few people, I haven't seen anybody else use them, but they self-adjust and they're spring-loaded.
