Graded building doors
We can provide you with bespoke graded building doors for your listed building or property.
Graded buildings are often put to modern uses, and as such they need as much protection, if not more, than modern day builds. When a building is graded or listed, itmeans that it has special qualities which need to be preserved. These are usually related to its age, rarity, or archaeological significance. For example, a grade I building is said to be of exceptional interest. Once it has been identified as a graded building, there are strict guidelines on any maintenance or repairs carried out in order to ensure it is preserved in its intended state.

Because of the importance of preserving these sites, our graded building doors are made to careful specifications and we take every precaution to ensure that any security door we install complies with National Heritage guidelines. Our design and manufacturing experts will painstakingly capture every detail of the original door in their drawings to be sure that the replica they produce is an exact match in every possible way.
