It’s possible to hang your own wallpaper, but the process is tedious and potentially frustrating, and it can be challenging to get seams to line up and look clean and professional. Plus, depending on the type of wallpaper you’re installing, using too much or too little adhesive could cause damage to your drywall or plaster, peeling, and bubbling in the final product. It’s usually a better idea to hire a professional wallpaper installer to do the work for you, as the relatively low cost is justifiable, if only to avoid damage to your walls.

Putting up new wallpaper tends to take one to two days, depending on the size of the area, whether old paper needs to be removed, and if there is any damage to walls that needs to be smoothed over or fixed.

When installing new steel doors, it’s smart to do other projects simultaneously. This can lower costs, limit mess, and help your home look and function better. For example, replacing a damaged doorframe is wise when planning door installations. 

Also consider changing broken or worn-out locks, repairing or replacing weather stripping, and updating handles. Painting, staining, or upgrading the trim around the door can also improve energy efficiency, security, and aesthetics.

To determine how many rolls of peel-and-stick wallpaper you need, measure the square footage of the walls you’re covering and divide that by the square footage that each roll covers. Add 10% to 20% of your total square footage to account for pattern matching or damage while installing.
