There are times when you pull up to a house and know there will be problems. And the problems can be predicted in advance of seeing everything. It's easy to begin because adding always gets to a sum total.
One half of a roof surface PLUS
One little downspout, come apart, draining at the front corner PLUS
A conveniently, eroded hole, about the middle of the house EQUALS
A REALLY, REALLY SMELLY, WET ROOM IN THE MIDDLE OF THE HOUSE!
Yes, we had to move some exercise equipment to see the extent of the moisture.
Yes, we did notice the moisture smell as soon as we opened the basement door to go downstairs.
Yes, I did have my thermal camera with me, asked in advance of the inspection to bring it!
Put the two images together in your mind to try to see the extent of the moisture in the room.
Interestingly, this was the only room affected.
There must be something going on in the foundation wall beside this room. Water appears to be getting inside only here.
That access panel on the wall is to the plumbing for the bathroom.
In that bathroom is a plastic shower surround, so the wall in the bathroom is not visible to the thermal camera.
Certainly there is some moisture there too, but there is NO odor.
The room in the thermal image is the only room with such moisture, which registered 100%. And it has been happening for some time!
My recommendation: the roof surface represents a lot of square footage of rain water. This is a large house, and for only one downspout to have been put to handle half of that roof's rain water, and draining it right beside the front corner, is a recipe for disaster. It is very poor planning on the part of the builder, and roofer, who designed the gutter system. ANY time you have a downspout draining beside a house, it is best to extend it outward to discharge its water into a swale or hill beside the house. Burying the extension tube is often the best way to handle it.
