How much does it cost to repair a crawl space?

Question

There's damp and a couple of rotten joists in the crawl space under my floor. What sort of price am I looking at to get it sorted?

Dragos Daniel · Answer

The cost will depend on the extent of the damp and how badly the joists are affected. For a couple of rotten joists and minor damp treatment, you could typically expect around £1,000–£2,500. If more joists or floorboards need replacing, or there is a significant ventilation or damp issue, the cost could be £3,000–£5,000+. I would recommend an inspection first to identify the source of the damp before replacing any timber, otherwise the problem may return.

Anywhere between £2000 and £10000 depending on damage and size

Oliver · Answer

A Carpenter and Joiner would correct this work for around £1600 - up to maybe £2200 including injection of DPC and plastering.
