Question 2

Does new wallpaper add value to my home?

Accepted Answer

•

Having dated, peeling, or otherwise damaged wallpaper can decrease the value of your property, so removing that before listing your house is nearly always a good idea; however, since wallpaper tends to be a personal style choice, potential buyers may or may not love your aesthetic as much as you do.

Love the look of wallpaper but want to consider property value as well? Stick with something that is easy to change. If you are thinking of selling soon, make sure your wallpaper hanging is on-point and looks professional with no crooked seams, evenly matched patterns, and minimal bubbling or other imperfections.

Painting over wallpaper is an efficient way to cover it if it’s in decent shape. Before painting over wallpaper, make sure the surface is clean and smooth. You may have to remove minor problem areas, such as lifted seams or small peels, with a sheetrock knife or putty knife. Add a latex- or oil-based primer to keep moisture at bay before painting. You’ll likely need two coats of paint to cover the area.
