Damp surveys in Cardiff: Homeowners vs renters

For homeowners:

You’re responsible for diagnosing and fixing damp in your property. If you're buying a property, a damp survey can help you renegotiate the price or plan repairs before moving in. If you already own a property, acting quickly can prevent more expensive fixes later.

For renters:

Landlords are generally responsible for damp caused by structural issues or necessary repairs. Report damp to your landlord or letting agent in writing. A damp and mould surveyor near you can provide evidence if repairs are disputed.
