Understanding your result
The headline is the total labour, and the sub-line gives the working days for your crew and the cost, either your supplies or the professional price. The three figures split the hours into stripping and repair and show the cost.
The table shows the area, the removal rate for the paper type and method, the layer multiplier, the stripping time, the repair time for the level you chose, the setup and cleanup, the total and the elapsed time for the number of people. If you are hiring, it shows the professional price with the layer multiplier applied.
Removal is the job before the job. The wallpaper cost calculator takes the removal cost as one of its lines; the primer calculator gives the primer for the bare walls afterwards, which need it; and the painting time calculator covers the painting if the walls are not being repapered.
How we calculate this
The removal rates are for one person and one layer: 150 sq ft an hour for strippable paper, 80 for peelable vinyl, 50 for traditional paper and 25 for paper that has been painted over. A steamer speeds the soaking types by about 30%; hot water alone slows them by about 20%. These are site figures consistent with the ranges in contractor estimating references, rounded, and the production rates guide explains how such rates are built and why your own timed wall is better. The production rates reference lists them with the painting rates.
The repair allowance is 15 minutes per 100 sq ft for washing off old paste and filling gouges, or an hour per 100 sq ft where the drywall face has torn and needs sealing and skim-coating. The paste and prep guide explains the repair, and why the paste residue must come off before primer or paint.
The assumptions behind the numbers
| Assumption | Default | Where it comes from |
|---|---|---|
| Strippable paper | 150 sq ft per hour | Site figure consistent with contractor estimating ranges, rounded |
| Peelable vinyl | 80 sq ft per hour | As above; the backing still has to be soaked |
| Traditional paper | 50 sq ft per hour | As above |
| Painted over | 25 sq ft per hour | As above |
| Method factors | steamer 1.3, solution 1.0, water only 0.8 | Site estimates |
| Extra layers | + 60% each | Site estimate |
| Repair | 0, 0.25 or 1 h per 100 sq ft | Site estimates for none, light and heavy |
| Professional rate | $1.50 per sq ft | Published cost surveys (Angi/HomeAdvisor, HomeGuide, Fixr), 2025: about $1–$2 |
| Supplies and rentals | $60 | Removal solution, scorer, scrapers, a day’s steamer rental |

The calculator does not model ceilings (twice as slow overhead), furniture moving, plaster walls (which tolerate soaking better than drywall), or lead paint under old paper. In homes built before 1978, scraping or sanding paint is regulated work under the EPA’s Renovation, Repair and Painting rule; the calculator does not cover it.
Two worked examples
A bedroom of traditional paper
350 sq ft, one layer, scoring tool and solution, light repair, one person.
- Stripping: 350 ÷ 50 = 7 h
- Repair: 350 ÷ 100 × 0.25 = 0.9 h; setup and cleanup 1 h
- Labour: 8 h 53 min, two days at six hours; $60 of supplies
If a corner peels away dry, it is strippable paper: the same walls are about 3 h 20 min, or $525 if a professional does them at $1.50 a square foot.
Two painted-over layers, with a steamer
Same walls, two layers, painted over, steamer, heavy repair, two people.
- Rate: 25 × 1.3 = 32.5 sq ft per hour
- Stripping: 350 ÷ 32.5 × 1.6 = 17.2 h
- Repair: 3.5 h; setup 1 h
- Labour: 21 h 44 min, 10 h 52 min each, two days
The repair is the hidden cost: torn drywall face over a whole room is a skim-coat job, and the primer under it must be a sealer, not ordinary latex.
Where to find your inputs
Area. The papered walls, from the square footage calculator.
Paper type. Lift a corner with a putty knife. If the whole drop peels dry, it is strippable; if the face peels and leaves a paper backing, peelable; if it tears in small pieces, traditional; if it is shiny and painted, painted over.
Layers. Look at a torn edge; several layers show as a stack.
Repair. Light if the wall behind is sound; heavy if you can see brown drywall paper or the plaster is damaged.
Common mistakes
- Soaking drywall too long. The paper face softens and tears.
- Skipping the scoring on vinyl or painted paper. The solution never reaches the paste.
- Painting over paste residue. It crackles the paint; wash it off.
- Priming torn drywall with latex. It bubbles; use an oil or shellac sealer.
- Underestimating layers. Check a torn edge before you plan the weekend.
- Forgetting the ceiling border. It is often a different, stubborner paper.
Questions people ask
- How long does it take to remove wallpaper from a room?
- For about 350 sq ft of traditional paper, one layer, with a scoring tool and removal solution, about 7 hours of stripping, nearly an hour of washing and filling, and an hour of setup and cleanup, so roughly 9 hours, two days at a steady pace. Strippable paper on the same walls is closer to 3 hours.
- What is the fastest way to remove wallpaper?
- Try peeling a corner dry first, because strippable papers come off in whole drops. For everything else, score the surface, soak it with a removal solution or hot water with fabric softener, wait for it to soften, and scrape. A steamer is faster on stubborn, layered or painted-over paper.
- How much does professional wallpaper removal cost?
- Published cost surveys put it at roughly $1 to $2 per square foot, more for several layers or painted-over paper. 350 sq ft of strippable paper at $1.50 is about $525.
- Does each extra layer double the time?
- Not quite. The calculator adds 60% of the first layer's time for each extra layer, because once the top layer is loosened the solution soaks through the next one faster. Three layers take about twice as long as one.
- Why is painted-over wallpaper so slow?
- The paint seals the paper, so water and solution cannot reach the paste. It has to be scored thoroughly or steamed, it comes off in small pieces, and it often takes the drywall face with it, which adds repair time.
- What do I do if the drywall paper tears?
- Do not wet it again. Seal the torn area with an oil-based or shellac primer, which stops the paper face bubbling, then skim-coat it with joint compound, sand and prime again before painting. That is the heavy repair setting.
