It looks like it's cut a little too long. Since winter is over it is expanding with the heat. That trim is PVC right? Plastic expands and contracts quite a bit.

^^this..it could also be something as simple as not enough nails, and what type they used.

The aluminum trim was nailed over fresh lumber that has dried and shrunk a bit. Was it treated lumber?

The concrete apron/slab may have heaved upwards slightly, "pushing" the trim and weatherseal wavy. You can trim a little off the bottom, or wait to see if the concrete settles again.

Thanks guys..the wood was not treated..my initial thoughts were there probably is suppose to be a certain amount of gap left for the wood to expand and contract and possibly some other tricks that the sidings guys would use..and I was thinking this probably was not installed properly in the first place..adding more nails and trying to fix it as it warps does not work !!!
