I hung this paper maybe a year before the Pandemic. It was a pretty new home, in the Towne Lake are of Cypress (NW Houston). Now, two or three years later, this pink patch has developed on the lower part of the powder room wall that backs up to the garage.
To me, my experience says this is mold.
There’s gotta be moisture inside the wall coming from somewhere.
The homeowner has already contacted the builder (thank goodness for warrantees!) and it’s certain that much of this wall will be torn out. Once the leak is fixed, the mold has been remediated, and the drywall patched, I will come in and replace the wallpaper.
This will entail either the one wall. Or possibly redoing the entire room.
The wallpaper is by Thibaut, and is called “Giselle.” The homeowner will replace it with exactly the same pattern and colorway.
