Hi, I'm looking to buy a house at the moment & the survey has come back suggesting that I'll need to replace the sarking felt in the loft, as it's not in the best condition. I've got two questions that I'm hoping someone will be able to answer: 1. Should we bother replacing it? 2. Approximately how much is it likely to cost to get someone in to replace it? I don't have the dimensions of the house, but it's a fairly typical 1950's two bed end of terrace. I'm just looking for a ballpark figure, really. Thanks for your help!
