Cost of painting interior walls/ceiling

Hello everyone,

At the moment, we are facing the question of how to approach the topic "Interior painting work."
Originally, the house (approx. 190m2) was ordered turnkey according to the contract.
- Klimapor walls in prefabricated construction -
This would have included filling to Q2, wallpapering with woodchip wallpaper, and painting solid white.
Since we definitely did not want woodchip wallpaper, we gradually removed this trade and currently only have filling to Q2 in the contract.

Actually, we wanted to award the trade to a local company now, but of course, it would be easier if everything came from a single source.
Therefore, I requested an additional offer from the main contractor again:
"Filling to Q3, painter’s fleece, and painting solid white" - approx. €28,000 gross surcharge.

To be honest, I lack experience regarding whether this amount is market-standard...

I would be very interested in your opinion on this.

And if the price is excessive, how would you approach the whole thing?
Somehow, I would have to squeeze the separately commissioned company into the construction schedule of the company.

Best regards and thanks in advance!

That is clearly too expensive. Get quotes from a painter. It doesn't take that long, so there is no need to worry about delays.

I am interested in the question + which material/processing method should be chosen? It should already be smooth

Sounds like a defensive offer

I'm not sure if it's really that ridiculously expensive. We have almost all rooms with Q3 and painter's fleece on the ceilings and brush plaster on the walls. On the one hand, you first have to find a painter who has the patience for such work and on the other hand really does a good job. We spent days filling and sanding. The fleece is then quickly on the wall later, but the preliminary work is extremely demanding. I can check our bill of quantities to see what the prices for Q3 + fleece were, then you can calculate it based on the area.

Q3 €16/m2 Blies €9/m2 Color €3.50/m2 €28.50/m2 net / approx. €33 gross Areas approx. 600m2 -> €20,000 gross Additional preparatory work such as masking, sanding, priming... possibly a surcharge for overhead work, meaning all ceilings, additionally window reveals, front door etc And then margin for the general contractor and you are at €28,000
