If you prefer peel-and-stick to traditional wallpaper, you can skip the priming process. Many manufacturers don't require an additional primer if you’re installing peel-and-stick wallpaper to painted walls. However, if you’re applying peel-and-stick wallpaper to unfinished drywall, you’ll need to apply a primer first.

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.

The pros of wallpaper include its durability and longer lifespan than paint, as well as its versatility. The durability can translate to lower long-term costs for upkeep and replacement, and the versatility means you have more options for customizing rooms in your home. Some downsides include that it’s difficult to remove, it’s not ideal for rooms or areas exposed to high moisture content or sun exposure, and it’s tricky to install. A professional wallpaper hanger can help mitigate these issues, though, by installing it properly and in areas suitable for wallpaper.

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.
