The West Coast has seen dramatic home price appreciation over the last two decades, a trend that permeated the entire region.

If it has permeated a porous material, like drywall, mitigation may be in order. 

Shortly after I got the trench dug on the problem side of house, water began to permeate the soil, and filled up the trench.  

All done the rewards are oh so sweet when you have a new asset with that new tenant smell still permeating the club house and your maintenance man is soundly asleep in the corner with the Maytag man!

Dirt and stains wont permeate the grout and if your lucky, will just need a quick clean and re-seal at turnover.

Any carpet that has had a dog lying on it for 4 years is going to have body oil imbedded in the carpet, as well as odors that have permeated the padding.

Hi Mark, if you're pulling the carpet out I would also apply a coat of the oil base primer on the subfloor, (especially if it is plywood) in addition to the ceilings and walls, to cover any odors that have permeated that surface.

Cigarette smoke permeation is a PITA to get rid of.

Even after stripping out all the carpet and padding the urine smell permeated the house!

I simply wanted to inform other BP members to a common, albeit important, misconception that permeates this site.
