Stone window sill repair, including stone corbel replacement, London

Stone corbel replacement by London Stonemasonry

London Stonemasonry were asked to inspect a stone bay window by a concerned homeowner in Kentish Town.

We confirmed that a corbel supporting their window sill had been badly damaged.

A corbel is a load-bearing structural stone, so its failure meant that a heavy sill was unsupported. This was causing cracking to the window’s stonework.

Repairing the Victorian stone window sill

We created a template from another of the window’s corbels, and hand-carved a new corbel from similar stone.

Once the carving was near completion we contacted the homeowner to arrange a suitable date to install. The old corbel was broken out by hand and the new one built into the brickwork on the same day.

By replacing one structural stone, the homeowner has minimised the need for more extensive, expensive repairs in the future.

Stone window sill repairs

The London Stonemasonry team have repaired, restored and replaced hundreds of stone window sills over the years.

For example in Stratford, East London, we revitalised a terraced home by restoring and decorating its bay window. We repaired the property’s stone sills by filling and sanding back the sills, sharpening their edges and enhancing their appearance.

In Dulwich, London, SE22 we replaced stone sills when we repaired a Victorian property’s bay window. This project also involved stabilising its first floor sills.

In Tottenham, we removed a UPVC window from a Victorian terrace and then installed a new window surround, including a new stone sill, decorative capitals, mullions, and lintels.
