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.

If you can already see the texture of the existing wallpaper through the layer of paint, then the texture could also come through the new layer of wallpaper. If that’s the aesthetic you want, then proceed. But if you want a smoother surface, you should either strip off the existing paint and wallpaper or hang a layer of liner paper before proceeding.

Hanging wallpaper may seem simple, but in practice it requires significant planning and finesse to make it look professional. To start, you need to get an even application of wallpaper paste across all of your wallpaper, which requires experience and large pasting tables to get right. You also need to plan out your design and match it exactly so that you don’t have imperfections in the finished product. It’s often better to hire a professional wallpaper hanger who can get the job done properly for a clean, smooth finish.

Many types of wallpaper exist, from removable peel-and-stick options to more permanent options that involve pasting. You can also find wallpaper that you can paint over, wallpaper with a texture, and wallpaper made from various materials, such as vinyl. Some types of wallpaper are washable, which can be a great option for kitchens or if your household has small children.
