This homeowner in East Stroudsburg, PA had Large 3000sf vented crawlspace with 1'' of foam on the block walls. The floor was thin concrete over dirt. Also in the crawlspce was the main boiler which ran there hot water baseboard heat,plus a 50 gallon water heater.
The family started noticing the moldy smells in their closets to the extent they could no longer store clothes and shoes there in the summer.
Using our patented drainage matting, 20 mil Cleanspace, closed cell spray foam to seal the walls and add R-value. Furthermore we sealed the vents and installed a new insulated steel entry door. We also added direct fresh air to the boiler. Now that we created a sealed, insulated space. We conditioned it with a Sanidry CX dehumidifier.
The home owner said it is so much more comfortable and there are no more musty smells!
Now that all the hot water heat pipes are in a conditioned area the boiler runs a lot less and the home is dry and healthy!
