By the square metre
The one you can check
- How it works
- Walls and ceilings are measured, and each line has its own unit price: so many metres of ceiling and so many of wall, at so much each. The total is the sum, and anyone can work it out again with a tape measure.
- What to check
- Which metres it means: painted surface, not the floor area of the home. Whether it deducts doors and windows or measures straight round without taking off the openings. And whether it charges the same for ceiling as for wall.
