The cost varies from $1 to $3 per square foot, depending on the type of wallpaper, the wall condition, and the labor involved.

Peel-and-stick wallpaper is designed to be removed without damaging walls, making it a good choice for renters or temporary design changes. However, damage to paint or drywall can occur under certain conditions. To prevent issues, the wall surface must be properly prepared before application—it should be clean, smooth, dry, and correctly primed or painted. Applying wallpaper to a freshly painted surface can cause the paint to peel off during removal. Additionally, removing the wallpaper too quickly or aggressively can also cause damage. For best results, always follow the manufacturer's instructions for both application and removal.

In most cases, it is not recommended to wallpaper over existing wallpaper, as the success depends on the type of paper already on the wall. While you might be able to cover non-coated wallpaper, you should never apply new wallpaper over a vinyl-coated one, which is more common. Doing so can lead to poor adhesion, resulting in bubbles, imperfections, and peeling. It can also trap moisture, potentially causing hazardous mold growth between the layers.

Even if the existing wallpaper is suitable, experts recommend applying only one new layer. Adding multiple layers (more than two total) can cause significant adhesion problems, leading to warping and bubbling. For the best results, the recommended approach is to remove the old wallpaper and all paste residue before hanging the new paper. If you are unsure about your wallpaper type, consider consulting a professional.

The simple nature of peel and stick wallpaper means it should come off much more easily than traditional wallpaper that is glued to your walls. You’ll still want to work slowly and carefully to avoid tearing it, but most peel and stick wallpaper should come off without a chemical agent to loosen it.
