Do you have a crawl space in your home?  Is the air in your home humid all the time or does the air have a musty smell?  I’ll help you get the answers you need to correct this issue.  I recently was hired for a home inspection in Glenview, Illinois that had crawl space issues.  The issues I found were definitely issues that I would correct because these issues will cause further issues on other systems if not repaired.

The first thing I check when I’m doing a home inspection in a home with a crawl is the flooring.  If the home has hardwood flooring I check to see if the hardwood flooring is crowning.  Crowning is a term used when hardwood flooring is in an area with very high humidity.  If this situation is not corrected then the floor will eventually be ruined and will require replacement.


The next area I would inspect is the actual crawl space and see what the condition of the area is.  The Glenview home inspection I was hired for had severe moisture issues that were compounded by the lack of a moisture barrier and/or a vapor barrier.  If you have a dirt or stone crawl space and you  have a limited budget but you still want to eliminate the moisture from your home then follow the next steps.  If your home doesn’t have any serious leaks in the foundation or from plumbing systems then this should correct your moisture issues.

1) Measure your crawl space.  The length by the width.  Take this number to your hardware store and purchase visqueen or sheets of plastic.  Buy double the amount. Also purchase a staple gun with 1″ staples and duct tape.

2) If there is any debris, clean this area out and rake out the stone or dirt until it is level.

3) Take the plastic and stretch it out to fit the entire area.  If your crawl space is very large you may have to overlap the pieces of  plastic.  If this is the case then tape these overlaps with duct tape.

If your crawl space doesn’t have insulation in the joists then you might want to add this prior to the next step.  The cost can vary but you can see a sample of what we think it should cost at ~  My clients from the Glenview home inspection needed this because their home didn’t have insulation in the crawl space.

4) Follow step 3 but staple to the joists  as you stretch it out.  This will prevent any moisture from entering the living area of the home.

If you have heating ducts that run through your crawl then you might want to consider having concrete poured over the visqueen to ensure that the moisture is contained.  If you don’t have ventilation you also might want to consider consulting with a contractor to have vents cut into the crawl space area.  As you can see there are many facets to a crawl space and they all can have their own issues.
