Some bricks on the front of my home are deteriorating; I
have no idea if it is an animal causing it or what.
you ever seen this or heard of this occurring before?
Any remedy or repair you could recommend?
Brick is porous, and the older it gets, the more likely
it is to deteriorate because of stresses created by
wall is in contact with soil. When it rains, or when
snow melts, water in the soil saturates the brick with
which it is in contact.
freeze-thaw cycle accelerates deterioration, called
spalling. Water penetrates the brick, and the surface
flakes and pops off, creating that chewed-off look.
say you can repair a spalled brick, but I believe the
solution is to replace it. You’ll also need to address
the cause: moist soil coming in contact with the brick.
removing the soil and replacing it with a couple layers
of roofing paper topped with crushed stone, so that any
moisture flows away from the foundation, will do the
I have a 13-year-old gas/forced hot air system with an
Aprilaire humidifier. I have not turned the humidifier
on for several years because of my concerns with the
my many filter cleanings over the years, I noticed that

My response is based on the flexible duct in my basement
that stretches from the furnace through the crawl space
under my kitchen addition. The duct has an insulation
layer surrounding the inner ducting.
I disconnected the duct to expose the interior, it was
bone dry, even though I use the furnace’s humidifier.
your case, I don’t think mold would be an issue since
you seem to maintain the ducts.
use your humidifier, but be vigilant.
