Underfloor venting

[marky9074]

Hi there,

My parents just got a quote for a complete replacement floor for their victorian terraced house. They have a bad damp problem, which after much work never seems to go away. Now this has been diagnosed as 'condensation' which I don't agree with and assume there is a leak somewhere which is the source of the damp.

What the builders are recommending is some ventilation system running under the new flooring to extract out the moisture. To me I would have thought it was better to pull up the floor, fix whatever is wrong, then a new concrete/screed floor?

What would you guys suggest?

Cheers,

Mark

Is there currently any ventilation under there?

I don't think so, I can't recall seeing any air bricks, and there is a lean to conservatory at the back.

What type of floor is it ?

1) A suspended wooden-floor

2) Block and beam

3) Other ?

At a guess would say suspended wooden flooring. I need to go and have a good look really...
