Hello, I'm about to sell the summer cottage and need all the information I can get about an issue that has come up:
During the inspection, the inspector noted the joists under the floor and suggested they could be impregnated with creosote. I don't interpret it as an assessment that it is so, but rather that it could be. But how do you determine which it is?
The house was built in the late 60s and stands on a crawl space.
I am grateful for any information you might have!
 
Hello! That this would be creosote, you probably can't determine just like that. Telephone poles were previously treated with creosote. The color was brown. If you have to find out what it is, you'll probably have to submit a piece for analysis.

Now I don't remember where I read this, but there is at least a study that shows creosote in the foundation shouldn't be dangerous!
 
Co > If you remember where you read it, I would be extremely grateful :-)

I'm not particularly worried that it would be the case; those I've spoken to who had some insight into the construction methods for the area at that time say it wasn't used, but it would be nice to completely rule it out.
 
Got hold of a nice person at the chemical inspection who had a quick response :-)
To use creosote-treated wood in gardens and playgrounds, the wood must be older than 30 years; after that time, the levels in the wood have decreased so much that the risk is negligible. This in turn means that the 40-year-old beams in our cottage are completely safe and can stay in place.

This is true if it's posts or sleepers that are outdoors and exposed to the weather. If it's in a foundation, the level is probably higher than if it had been outdoors.

However, I'm wondering what real impact it has if the floor is impregnated with creosote. These aren't substances that become airborne; rather, they go into the ground if they go anywhere. Of course, it becomes a problem if you have to demolish the house; then you have to dispose of the creosote materials at a landfill.
 
How did it go with the creosote?
I have a summer cottage that we're in the process of renovating and I discovered that apparently creosote was splashed on when it was built in the 60s?
Should one replace the beams or what should be done?
