The finishing mistakes that cost you twice
Most finishing problems come from decisions taken back at the shell stage. The common mistakes, and how to avoid them.

Most finishing problems do not start at the finishing stage. They start at the shell, when the electrical and plumbing routes are set out without an interior design.
The five most common mistakes
- Setting out the electrics before the furniture layout is designed
- Starting the finishes before the plumbing has been pressure-tested
- Choosing materials without an approved sample
- Skipping the waterproofing in the bathrooms and on the roof
- Agreeing to “super lux” with no written specification
The right order for finishing
| Stage | What is done | Before you move on |
|---|---|---|
| 1 | Electrics and plumbing | Pressure test, and photograph the routes for the record |
| 2 | Plaster and waterproofing | Flood-test the waterproofing |
| 3 | Floors | Approve the ceramic and marble samples |
| 4 | Paint and joinery | Check the colours on the wall, not in the catalogue |
Frequently asked questions on this topic
01When should finishing start after the shell?
Once the concrete has had its time and the plumbing and waterproofing have been tested. Rushing this stage is expensive.
02Are samples really necessary?
Yes. Colour and texture differ between the catalogue and reality, and a signed sample settles any dispute later.
