How can you eliminate the odor of burnt wood from crawlspace

by Pag11888742
The crawlspace under my laundry room has a terrible odor coming from it. I can see that the floor joists had apparently been involved in a house fire at one time and had been replaced/repaired with some new wood, but not all. I Think that is the source of the bad smell, but am uncertain. Floor feels solid, but wonder if there is a way to treat the burnt joists to eliminate the smell.

    Hi Page I would make a mix of 50/50 vinegar and water and hose it down then leave a box of baking soda in there. If that doesn't take care of it you could try bleach and then sealing the wood with a poly acrylic.

    I had a painting business for quite awhile. There are products that can be painted and/or sprayed to cover up the odor. Check with a paint dealer to find the best current product to use.

    If you have a smell what is it? Burnt, rotten dead things. Fist identify what the smell is. It is possible that you have a leak in the plumbing. Find and fix the source of the smell first. I would also remove and replace any insulation that is discollored or wet. remove and replace the vapor barrier in the crawl space. Go to your local big box home improvement store and get some of the mis mixed pait that they always have. Paint the area under the house. I would use a sprayer and then back brush it. This will mseal the wood and incaplulate the smell. If possible use a light colored paint. Painting the area will make future forays into the crawl space a little more plesant. Remove all forigen material from under the house.
