My property has damp in the loft conversion - across the ceiling and down the wall. Does anyone come out and give free estimates?

would say most people give free estimates. Place your requirements in the Post a Job section,and you can than pick and invite the interested tradesmen.

Hi your damp may becoming from the roofing tiles or split roofing felt, if we are in your area contact us and we will come and have a look Thanks

Most company's should do free estimates

If the correct ventalation has not been fitted when the loft conversion was done and it is now always damp, over time this may cause rot in the roof timbers and could become a very expensive repair. I would consult a proper builder or roofer for advice, they shouldnt charge normally for this.
