The average cost to remove wallpaper is $790. The final price tag depends on the size of the room and the complexity of the project, and can range from $200 to $2,000. Usually, removing peel-and-stick wallpaper is on the lower end of the cost scale, as it doesn't require special tools to remove.

Using a fabric softener solution is a popular and low-cost DIY method for removing wallpaper, but its effectiveness is limited. While it may work on some types of wallpaper, it is unlikely to be successful on vintage styles, and there is no evidence that it is more effective than other removal methods. There are also several potential downsides: the solution can leave behind a residue that may damage your walls or interfere with the adhesion of new wallpaper. Additionally, this method can create a strong, overpowering aroma that takes a long time to dissipate, making it a poor choice for homeowners sensitive to smells.

The average cost to install or hang wallpaper is around $575 per room or project, with typical prices ranging from $200 to $1,500. Costs can be higher for custom or luxury products. Since project size varies, it's often helpful to estimate labor costs per square foot, which generally fall between $1 and $7, with an average of $4 per square foot. The total cost depends on several factors, including the quality and type of wallpaper, the size and type of the room, and whether old wallpaper must be removed first. Opting for less expensive materials like peel-and-stick wallpaper or choosing to do the installation yourself can lower the overall cost. For the most accurate estimate, it is best to have a professional inspect the space and provide a quote.

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.
