Use of Traditional Materials and Expert Advice for Repairs
Most repair work to historic buildings requires traditional materials and specialist skills. Owners should seek expert advice from the Department's Environment and Heritage Service and relevant guidance publications.
Most repair work to historic buildings will require the use of traditional materials and in some cases may involve specialist/traditional skills, so when employing a builder it is essential to make sure he is prepared to take the correct approach. Listed building owners should not hesitate to seek expert advice from the Department's Environment and Heritage Service who can provide professional guidance on the use of materials and restoration techniques. Environment and Heritage Service has published "An Owner's Guide" to caring for listed buildings, a series of Historic Building Technical Notes and, in conjunction with the Ulster Architectural Heritage Society, has also published a "Directory of Traditional Building Skills". These three references should prove a useful source of information to all listed building owners and are obtainable on request from the Environment and Heritage Service.
