Your peel-and-stick wallpaper can fall off for multiple reasons, including high humidity levels, extreme temperature changes, poor installation, and even the wall surface. Textured walls can prevent the adhesive from fully sticking to the wall, making it more likely for the wallpaper to peel off. Low-quality wallpapers with weaker adhesives are also more likely to fall off prematurely.

Having dated, peeling, or otherwise damaged wallpaper can decrease the value of your property, so removing that before listing your house is nearly always a good idea; however, since wallpaper tends to be a personal style choice, potential buyers may or may not love your aesthetic as much as you do.

Love the look of wallpaper but want to consider property value as well? Stick with something that is easy to change. If you are thinking of selling soon, make sure your wallpaper hanging is on-point and looks professional with no crooked seams, evenly matched patterns, and minimal bubbling or other imperfections.

Ideally, you want to ask the wallpaper installers you’re considering for examples of past work, and references you can call. These will prove that the installer can handle your job, make your room look professional, and will also give you some insight into the kind of customer service you can expect. Before you start calling companies, you might want to narrow down your options by finding installers with mostly positive reviews online.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay.
