Historic Building Cleaning


ThermaClean work primarily with registered building masonry and we advise on the surface treatment historic monuments. Our intentions are to clean the surface of stone, brickwork or other materials without damaging the substrate or altering its natural appearance. Our aim when cleaning an historic building or monument is to make it look clean – not new.




ThermaClean can be engaged to produce on-site trials and reports. These are used to establish appropriate methodology, specification and exemplar panels. Consultancy often extends to site meetings both before and during the works, to help mediate and manage the expectations of client, architect, conservation officer and contractor.
