Damage to render and paint
Evaporation of moisture and salts can cause render to crumble and paint to flake.
Consequences
Possible consequences of moisture in buildings
Untreated moisture does not remain a cosmetic problem: it can damage coverings, encourage mould and complicate a sale or works project.
Short answer
The consequences of moisture first affect coverings and comfort, then the clarity of a property. They must be distinguished from the causes: to limit them sustainably, the source of the moisture has to be treated before cosmetic work.
Visible effects and less visible effects
Wallpaper and coverings
Coverings peel away or blister when the substrate remains damp.
Mould and indoor comfort
Air that is too humid encourages mould and makes rooms less comfortable to live in.
Humid air is harder to heat
The more moisture air contains, the more energy is needed to heat it. No specific savings figure is claimed.
Reduced clarity before a sale or works
Visible issues that are not explained can complicate a sale, a project or an insurance claim file.
Why treat the cause before cosmetic work
Masking the effects without treating the origin often means doing the same works again later.
