We are building a house near a creek on the Cheasapeake bay. We have seen many rusting crawl space doors. Do you know of any manufacturers who have good non-ferrous crawkl space doors (with strong frames and locks). Many thanks, George B. Mitchell
P.S. we are following your advice with a rat slab/6 mil liner and pipe insulation - with R-19 on the floor above the crawl space. Any other suggestions?
