INTERNATIONAL BASEMENT FORUM

Choose your language – share basement problems and real experience

The same basement problems appear across borders: damp walls, mould, drainage, condensation, radon, low floors and foundation work. The goal is to collect real questions and experience in local languages and make the technical lessons easier to share.

Choose country / language

Important: This is an international forum and knowledge project. KÆLDER-RENOVERING is a Danish contractor and does not claim to carry out construction work in every listed country.

Share enough detail for a useful answer

Include your country or region, the age of the building, clear photographs and a short description of when the problem appears. Do not publish passwords, identification numbers or other sensitive personal information. Complex structural, drainage or regulated work may still require a qualified local professional.
