Patio Door Threshold Issues
I bought a new construction a few years ago and the house has been settling. The patio has settled quite a bit and now there is a noticeable gap between the patio door threshold and the concrete. There was a wood board that used to fit snugly into this space, but now it leaves a gap and does not support anything. The gap is uneven in height and depth along its length. Is there any easy way to measure and cut a piece of wood to fit snugly into this space? And what should I use to glue the wood to the concrete? I suppose I could just use wood shims (although I'm not sure I could find any that are pressure treated/weather proof)?
