"The OnCall team does wonderful work installing wallpaper! They are very communicative, thorough and clean. I have worked with them on many projects and they always do a great job! They also do repair work seamlessly (we had them do one on an older install that was by someone else we had extra paper for). The team members have a good eye and are experts in their field."

Wallpapering questions, answered by experts

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.

Yes, many installation and painting services include wall preparation, such as patching holes, smoothing surfaces, sanding, and priming. It is recommended to confirm the specific preparations included with your provider.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

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.

In most cases, it is not recommended to wallpaper over existing wallpaper, as the success depends on the type of paper already on the wall. While you might be able to cover non-coated wallpaper, you should never apply new wallpaper over a vinyl-coated one, which is more common. Doing so can lead to poor adhesion, resulting in bubbles, imperfections, and peeling. It can also trap moisture, potentially causing hazardous mold growth between the layers.

Even if the existing wallpaper is suitable, experts recommend applying only one new layer. Adding multiple layers (more than two total) can cause significant adhesion problems, leading to warping and bubbling. For the best results, the recommended approach is to remove the old wallpaper and all paste residue before hanging the new paper. If you are unsure about your wallpaper type, consider consulting a professional.
