If your original timber frames are beyond repair, our craftsmen build beautiful timber sash window replacements. Designed to exactly match original profiles, our new windows blend seamlessly with your home's historic facade.

We work with premium Accoya® wood to provide maximum durability, backed by a 50-year warranty against wood rot. Battersea's housing stock ranges from Victorian terraced streets to Edwardian conversions. Sills and frames here are often upgraded with Accoya wood to resist dampness from the nearby river Thames.
