Check a room plastering quote

Paste the quote you were given and enter your measurements. Every line is read against the job: what the quote leaves out, what it adds, which quantities sit outside the computed range, and what to ask. Quantities only — never prices.

How the quote is read

Each line of a room plastering quote is matched to the line of the job it names, or marked as something the Plaster a room takeoff does not measure — labour, removal, hire, fees, or anything else.

The job’s own figures come from 5 measurements — room length, room width, wall height, external corners, stop bead runs — run through the same calculators as the takeoff, so the two give the same figure for the same job.

Reading a room plastering quote

Plastering is quoted per room or per area, and the plaster itself is rarely itemised — which is why the beads and the protection matter here: they are what a low figure most often leaves out.

Counting your own corners is a quick check on the bead lines: an angle bead for each outside corner, a stop bead wherever the plaster ends against another material. Whether the walls are skimmed or floated and set changes the price more than the size of the room does.

Three steps

  1. Give your measurements. The page opens on a typical job so it has something to show.
  2. Paste the quote's lines as they came, or add them one at a time. Leave the prices in — they are taken out, never read.
  3. Read the report: what is left out, what is added, what sits outside the range, and one list of questions to send.

  • What it leaves out

    Every line the job needs that nothing on the quote reads as, with the quantity your measurements produce.

  • What it adds

    Lines this job's takeoff does not measure — labour, removal, hire, fees, anything else — each named for what it is.

  • What sits outside the range

    Quantities above or below the computed range, by how much, in the quote's unit or converted and shown.

  • What to ask

    One list of questions, in the quote's order, ready to copy and send. Questions, never a verdict.

Paste the quote above, or add its lines one at a time. The reading appears here as each line is read.

Outside what this takeoff measures

4

Nothing in the reading measures these. Whether the quote covers each is worth asking in its own right: a scope missing from a quote tends to become a cost after work has started. Why each is left out is on the takeoff.

The reference

Every line the reading looks for

For Room length 16.5 ft · Room width 13 ft · Wall height 8 ft · External corners 2 · Stop bead runs 6Room length 5 m · Room width 4 m · Wall height 2.4 m · External corners 2 · Stop bead runs 6. Each is the calculator linked under it, run with those measurements; a range is that calculator at both ends of one choice, not a margin for error.

How the ranges are taken

Where the choice is cutting waste, the ends are the site’s own allowances: 5%, the tight buffer of a crew with a planned set-out, and 15%, the wider one a first-timer orders. Where the calculator decides between patterns or materials, the ends are the options it offers. Where it adds nothing for loss, the range runs from the net quantity to 15% over it.

A minimum — the fewest hangers a spacing allows, the least airflow a room needs — has no upper end. A single figure carries an allowance the material itself needs, such as a lap, and names it.

What a reading like this cannot see

  • It does not know your prices, your market, or what the work ought to cost.
  • It does not know the building — the access, the condition of what is there, or what has to happen first.
  • It cannot check a lump sum, because there is no quantity in one.
  • A line it reads as missing may be priced under another name. A quantity outside the range is not evidence of anything. Each is a reason to ask a question.
  • Two quotes are not comparable until their scopes are.
  • It is not advice, and it is no substitute for a second quote.

Frequently asked questions

What quantities does a room plastering job need?
It depends on the measurements, so this page asks for yours. At the size it opens on — Room length 5 m · Room width 4 m · Wall height 2.4 m · External corners 2 · Stop bead runs 6 — the lines come to: Plaster Angle and Stop Bead, 8–10 lengths; Skim Coat Plaster, 166–182 kg; Drywall Joint Tape, 112–123 m. In imperial units — Room length 16.5 ft · Room width 13 ft · Wall height 8 ft · External corners 2 · Stop bead runs 6 — they come to: Plaster Angle and Stop Bead, 8–10 lengths; Skim Coat Plaster, 369–404 lb; Drywall Joint Tape, 370–405 ft.
Which line on a room plastering quote varies the most?
The Plaster Angle and Stop Bead: 8–10 lengths for a job measured Room length 5 m · Room width 4 m · Wall height 2.4 m · External corners 2 · Stop bead runs 6, depending on how much is allowed for loss over the net figure, up to 15%.
What does a room plastering quote often leave out?
The reading names every line of the job that nothing on the quote reads as — any of the 3 lines the takeoff measures. The takeoff also lists 4 things it does not measure, shown under the reading, and each is worth asking about: a scope missing from a quote tends to become a cost after work has started.
Can I paste the quote exactly as it came?
Yes — from an email, a PDF or a spreadsheet, one item to a line. Amounts of money are taken out before anything is read, headings and totals are skipped, and each line is shown with what it was read as, so a misreading is one correction. Quantities in the other unit system are converted and the conversion is shown; a count of boxes is never compared with a count of tiles.
Does this check the price as well?
No. It reads quantities, never prices, and this site publishes none: an installed price moves with the market, the season, the access and the specification, so a figure for what the work ought to cost would give you confidence in a number nobody can defend. A quantity against your own measurements is checkable, and every figure here links to the calculator that produced it.
