Facade discolored after 4 years

wow! then we're moving out again!!


we live in the countryside, here all houses have white facades. The pollution has noticeably increased again over the past year, let's see how it continues.


what was the reason with you? Is your renovation a common procedure?


thanks for the answer, but the discolorations are widespread and chemicals/poison would only be the last resort

wow! then we’ll move out again!!

You can stay living in the house during façade work.

we live in the countryside, here all houses have white facades. Pollution has increased significantly over the past year, let's see how it develops further.

We also live in the countryside and I see many clean facades with shadows or stains. Therefore, we decided on a rustic untreated larch wood facade, which slowly "ages gracefully."

what was the reason on your side? Is your remediation a common procedure?

During construction, our site supervisor complained about the too small distance between the wall and the plaster rails at the windows, as this meant the base plaster had been applied too thinly. When the rails were reapplied, presumably a gypsum-based adhesive or gypsum was simply used without anyone noticing. Water entered through microcracks in the plaster and gradually caused the gypsum to swell at these spots. We filed a defect report about the cracks at the window reveals when they were about 0.5-1 mm wide. The wider the cracks became, the more water penetrated the gypsum and the faster the cracks grew. If they had addressed it right away, they probably would have just repaired the reveals and it would likely have lasted until after the warranty period, but fortunately, the construction company took their time fixing the defect, so simply filling it was no longer possible and the root of the actual problem was investigated.

The plaster rails had to be reapplied, the plaster removed at those spots and rebuilt. Since the transitions between old and new plaster would never have worked properly, fabric was applied over the old plaster and then completely replastered. This was all discussed between the general contractor and our site supervisor/expert. Whether this is a common procedure or not, I can't say.

We also live in the countryside and I see very many plaster facades with shadows or stains. That’s why we decided on a rustic untreated larch wood facade, which slowly “grays gracefully.”

We have that too, but only partially.
I do wonder if I’m being too picky, but it just looks increasingly worse ... and a different plaster system than required.

Thanks for your long reply, at least you were lucky in the end.

I am indeed wondering if I am being too picky

Well, as long as you still have a warranty, I would first assert the defect, especially if lower-quality paint than agreed upon was used.
Whether the damage can actually be repaired or you will be financially compensated is another matter.
Even though white with anthracite-colored windows is very trendy right now, you see the dark spots most quickly there.

Yes, definitely, especially since the plastering company was already insolvent at the time – so the general contractor couldn’t approach his subcontractor, and our general contractor also passed away shortly after the 5-year warranty period.
