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.

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 two most common reasons wallpaper does not stick are a lack of preparation and improper adhesive. Be sure to use the wallpaper paste designed for the type of paper you choose. Before beginning your project, make sure the walls are clean and free of dust, grease, and oils.

While some people are confident in their ability to replace concrete by drilling out the broken pieces and replacing them with bagged concrete, it’s possible to run into snags that make hiring a professional worth it. Trying to level concrete slabs can require special equipment, which can be pricey to rent and tough to operate. It's also crucial to contact your town's municipal office to ensure you are allowed to take on the project without a permit.
