How much does a damp specialist cost in Llantwit Major?
Most damp & mould jobs in Llantwit Major start from about £205, and better ventilation (extractor fans) is typically £270 – £370. Prices in Wales are worked into every figure. Answer a few questions above for your own price.
Is it condensation or rising damp?
Mould on ceilings, corners and window frames is usually condensation. Tide marks low down on walls can be rising damp. A proper look tells you for sure.
Is mould dangerous?
It's worth dealing with, especially for children and anyone with asthma. Wipe it with a mould remover and keep rooms aired.
Do I need a damp course?
Not always. Many 'rising damp' problems are actually from high ground levels, leaky gutters or blocked air bricks.
