Unfortunately, getting rid of the odor will be a challenge. There is a solution that is fairly effective in getting the odor out of clothes, off pets, etc. but it could potentially discolor siding. If you use it, test it on a small area to make sure it doesn't stain the foundation or siding before applying it to large areas.
Solution for Skunk Odor Removal
Mix 1 quart 3% hydrogen peroxide solution, ¼ cup baking soda, and 1 teaspoon liquid soap. Do not add water. This solution can be used to wash skin, clothes, dogs, etc. that have been sprayed by skunks. Due to the peroxide, the solution may lighten the fur of pets.
While the solution will get rid of the smell faster than letting it "weather", it won't get rid of the smell overnight. And repeat applications will likely be necessary. What are you using to bait the traps?
