Painting over wallpaper in a New York City apartment seems like the easy shortcut to avoid the misery of wallpaper removal. In some situations, it works. In most, it doesn't — and the failure is ugly, expensive to fix, and entirely predictable. Here's how to make the right call.
When Painting Over Wallpaper Might Work
Painting over wallpaper has a chance of acceptable results when: the wallpaper is older, flat-pasted wallpaper that is firmly adhered with no peeling edges or bubbles; the seams are tight and flush without visible ridges; the wallpaper pattern is light enough that primer and two coats of paint will obscure it; and the substrate behind the wallpaper can handle the moisture of paint without causing the paper to bubble and lift.
Why It Usually Doesn't Work
Most wallpaper painting projects fail because: the moisture of the primer causes the wallpaper edges and seams to lift; the pattern of the wallpaper telegraphs through the paint; the painted wallpaper is significantly harder to remove later and causes more substrate damage; and in pre-war apartments with original plaster, the wallpaper may be the only thing holding the plaster together in some areas — removing it (or disturbing it with paint moisture) causes plaster sections to fail.
What Wallpaper Removal Actually Costs in NYC
Professional wallpaper removal in New York City runs $2 to $5 per square foot, depending on the number of layers, the condition of the adhesive, and what's underneath. A standard bedroom (about 400 sq ft of wall surface) runs $800 to $2,000 for removal alone. Add skim coating after removal (almost always necessary): $2.50 to $5.00 per square foot. Total cost to properly prepare walls after wallpaper removal in a typical bedroom: $1,800 to $4,000 before any painting begins.
The Bottom Line
If the wallpaper is in poor condition, has multiple layers, has visible seams, or is in a room where finish quality matters — remove it properly, skim coat, prime, and paint. The upfront cost is real but the result is a wall surface that will hold a beautiful finish for years. Painting over poor wallpaper and then repainting over the failure costs more in the end.
