A feature that also protects
A cornice is the projecting stone moulding at the top of a wall, below the roof or parapet. It adds character to a building, but it also helps throw water away from the face of the wall. Because cornices project outward and sit high on the building, they are heavily exposed to wind, rain and frost.
Why cornices fail
- Water getting behind the stone from leaking gutters, failed lead or a defective parapet
- Corrosion of iron cramps or dowels, which expands and splits the stone
- Frost damage on porous stone
- Weathering of mouldings until the profile is lost
- Past repairs in hard cement that have cracked away
Where a cornice is loose or cracked, there is a risk of pieces falling, which is a safety concern for people below. If you can see cracks, gaps or movement in a cornice above a footpath or entrance, it should be looked at promptly, and the area may need to be made safe first.
Our approach
Safe access comes first, usually scaffolding. We then inspect the stonework and the structure behind it. Loose elements can be secured, damaged sections replaced with new stone cut to match the profile, and eroded detail repaired with compatible mortars where appropriate. Rusting ferrous fixings are replaced with stainless or other non-corroding alternatives. Often the gutter, flashing and parapet detailing above also needs attention, otherwise the water that caused the problem will continue to do so.
Local buildings
Newcastle city centre and Tyneside have many Victorian and Edwardian commercial buildings, banks, villas and terraces with stone cornices and moulded eaves. Coastal exposure in Tynemouth and nearby seaside towns adds salt and wind that can accelerate decay.
Related work
Cornice repairs often go hand in hand with parapet wall rebuilding, lead flashing replacement and stone sill restoration.
Listed buildings and conservation areas normally need consent for external alterations, and some work may need scaffold licences if it overhangs a public footpath. Start with the Planning Portal to see what applies.
Frequently asked questions
Is a loose stone cornice an emergency?
It can be, particularly above a pavement, doorway or shared area. If stone is visibly loose or has moved, keep people away from below it and arrange an inspection promptly.
Can a damaged cornice be repaired in place?
Often yes. Sound sections can be secured and damaged parts replaced or repaired. If the stone is badly decayed or the fixings have failed, sections may need to be taken down and replaced.
