So we had a little flooding here in N Ankeny if you haven't heard... We just got our walls tested and we are dry and mold free. But I had to drill 1 inch holes along the baseboards to dry the insulation out. The worst cavity was only wet an inch up so we were very lucky.

My thought was to spray foam insulation in to fill the void where the insulation was pushed up. But I'm concerned about creating a bad vapor barrier. I'm guessing this is either a great idea or a terrible idea and wondering what you smart folk think.

There's a lot of bad information out there regarding spray foam (SPF). Much of this bad info is coming from traditional insulation companies afraid of competition. SPF is a much better option than traditional fiberglass insulation, but it will cost you a bit more. Yes there can be vapor barrier issues, but what you need to do is find a reputable SPF contractor and they should be able to tell you what's what in your specific case. SPF is not easy to install, so make sure you're dealing with someone who's been in business for a while.

Good luck!

We spray foamed our house after I gutted it. Best choice we made. We used a guy who has done a lot of work (I believe we was spraying the owner of Hickory Parks house the same time he was doing ours). I can get you his info if you want. He was super helpful in answering all my questions.

Don't know about basements, but we did our addition and garage, it is so nice. Warmer than the rest of the house in the winter.
