A Leading Damp Proofing & Timber Treatment Company in Bristol - Brunel Preservations Ltd We provide damp proofing and timber treatment services in Bristol for a number of years At Brunel Preservations we have seen timbers turned to powder by woodworm and into sponge by wet rot. We've found giant dry rot fungal growths lurking under floors and seen homes ruined by rising damp. We've seen brick walls bow and crack because of failed wall ties. But the good news is, we fix, treat, repair and replace every one of these conditions on an almost daily basis. We are an independent family firm who has provided timber treatments and damp proofing in Bristol for a number of years. We work with everyone from individual home owners to local authorities, property developers and building contractors who all value our high level of skill, knowledge and experience.
