The average cost of wallpaper installation is around $550 per project, or between $200 and $1,500, for most homeowners. Since projects and application areas vary wildly by size, it’s usually more helpful to have an estimate per square foot, which is between $1 and $7 per square foot, or an average of $4 per square foot. Project prices can fall above this range, though, especially if you purchase custom wallpaper or a luxury product. The best way to get an estimate for your project is to have a professional inspect your space and provide a quote.

Wallpaper lasts an average of around 15 years, but there is some variance. The type of wallpaper matters, as vinyl wallpaper tends to last the longest—sometimes 20 years or more—while a peel-and-stick wallpaper, which is the easiest to install for DIYers, will usually only last for around five years. Exposure to high humidity, smoke, and UV rays from sunlight can also limit the lifespan of your wallpaper, as can heavy traffic in the installation area.

Most experts would not recommend hanging wallpaper over existing wallpaper more than twice. Even if the walls are in good condition and primed well, that third layer of wallpaper could cause problems with adhesion. Unless you like bubbling paint and peeling wallpaper as an interior design choice, it’s better to remove at least one existing layer before adding any more to a wall.

In most cases, you cannot wallpaper over existing wallpaper. It’s possible to wallpaper over non-coated wallpaper, but vinyl-coated wallpaper is much more prevalent in homes, so you generally shouldn’t put new wallpaper over existing wallpaper. Adding a layer of wallpaper over vinyl-coated paper will lead to poor adhesion, leaving behind bubbles and imperfections in your wall. Plus, wallpapering over vinyl-coated wallpaper can lead to mold growth, which can be hazardous to your health. It’s usually best to hire a local wallpaper removal service to handle the task to avoid these issues.
