Re: wood floors buckling after kitchen addition
Howdy. Hope you have plastic on the dirt in the crawl space to keep the moisture out of the house. If not consider installing 6 mill and caulking it to the foundation walls to keep the moisture in the soil and out of the house. Might have a wood flooring company out to look and tell you what they suggest- as these people see a lot of problems.
Structural enginer ask for a verbal report at the inspection before you pay the $$$ for a written report - just to save you some $ .
Any an all of my comments are just my opinion and not to be confused with facts.
