Services we offer: From bay window design to complete restoration
Not all stone bay windows need an entire rebuild and we have huge knowledge and skill in bay window restoration. We offer a full service; repair, restoration, replacement and redecoration of the completed works.
- Design: We undertake all design aspects of the works. For example, detailing and precisely measuring neighbours’ windows to give an exact copy or from drawings provided.
- Bespoke design: We also offer bespoke personalised designs for your bay window. While retaining all period correct design and ratios, your window stonework can reflect your individuality.
- In the Georgian and Victorian eras, it was very common for new home buyers to have input into the design of their new homes as they were being built. If you keep a keen eye out, you can spot how designs of bay windows and entrance ways can change on the same terraced road.

- Repair and rebuild: We breathe life into worn and failing stonework by piecing in new elements of stone and repairing other aspects with restoration repair mortars.

A client testimonial
Sarah O’Brien, homeowner, Chiswick, London, W4:
“The new bay window [by London Stonemasonry] is a testament to the skill of these amazing stonemasons. The Bath stone they used is beautiful and adds a warmth to the house. Its carving is exquisite and matches all the details of neighbouring properties. It’s precision perfect – when my new sash windows were fitted the company commented that they had never fitted a window where no adjustments were necessary.
“The added bonus of using London Stonemasonry was that their team could handle all aspects of the renovation – from removal of the render, rebuilding and damp proofing the bay window, re-roofing the structure and making good inside my home.
“I wholeheartedly recommend their skills to anyone who is looking to do a similar project.
