Services
Draught Proofing
Our draught proofing service eliminates rattles and heat loss by installing hidden weather seals and refurbishing sash components. We service pulleys, replace cords, and fit quality fasteners to ensure smooth operation. This service preserves listed buildings while improving energy efficiency, with results lasting generations.
Double Glazing
We install double glazed sash units into existing frames, offering Fineo vacuum glass (U-value 0.7W/mK) and Nicholls & Clarke slimline units. This minimises disruption compared to full replacements, enhances thermal performance, and reduces external noise without compromising heritage aesthetics.
Box Frame Repair
Damaged box frames are repaired using FSC-certified timber and Repair Care epoxy resin. We replace mullions, stiles, and fascias, ensuring structural integrity while maintaining original profiles. Repairs comply with conservation standards for listed properties.
Sash Replacement
Broken or rotten sash panels are restored using traditional joinery or replaced with custom-made units. We adjust counterbalances for proper function and fit 4mm glass, ensuring seamless integration with existing frames and optimal performance.
Timber Repair
Minor timber damage is repaired with epoxy resin systems recommended by heritage specialists. Knots are treated, and all work is primed and blended to match original finishes, preserving the window's appearance and structural integrity.

Report
I run a serviced office space in a grade II listed building on Lewes High St. Dan and his specialist team recently repaired most of our sash windows that were in a very poor state. They managed to repair the damage with careful planning, met allocated timescales, with no disruption to business. They were professional, friendly and did a good job of tidying up afterwards. I would highly recommend them to any business or home owner. Thank you Dan and team!

Report
Dan and his team did a great job renovating our very old, wonky windows. Being a very old house, nothing was easy but they kept at it and nothing was too much trouble. They were also very tidy and good value for money. Would definitely use again.
