Dulwich Sash Windows

Sash Windows Portfolio

Quick Contact

Replacement box sash windows are our particular area of expertise and we pay close attention to the design and detail of the original windows, replacing old single-glazed with modern double-glazed construction, whilst maintaining the appearance of the original. Our casement windows are always constructed out of hardwood to ensure a durable product.


Our construction methods and moulding details are increasingly being copied by other local window manufacturers!

"Thank you for our new sash windows, they certainly keep the street noise and dust out and we are looking forward to a much warmer winter this year."

Peter, Forest Hill
"We have had new sash windows built by Oak Joinery and their workmanship is great, we were also pleased with the fact that they gave good advice with the planning applications."
