The Home Improvement Advisory Service was established in 1993 - and for over 23 year we have been helping homeowners plan and organise building work and home improvement projects, including new roofing and roof renovation projects.

Our aim is to offer a one stop solution - from helping with your initial specification; to advising on high quality products; and recommending reputable trades-people and businesses to carry out the work - and if required having the work managed by an experienced project manager.

Independent surveys

WE provide independent surveys, roof inspections and reports. Our advisory reports will highlight defects that will help solve damp problems. We also provide detailed specifications for new roofs and roof renovation projects.

Re-roofing is the ideal time to look at improving energy efficiency, as it often exposes un-insulated parts of a building
