Services
Sash window renovation
Our sash window renovation service involves complete assessment, box frame restoration, and sash refurbishment. We reinstate smooth operation through planing, pulley servicing, and installation of draught-proofing systems. All work preserves original architectural details while improving energy efficiency, with 5-year guarantees on completed projects.
Cill replacement
We specialise in replacing decayed window cills using matching timber to maintain period authenticity. The process includes precise measurement, traditional joinery techniques, and draught-proofing integration. Each replacement ensures structural integrity while enhancing moisture resistance and thermal performance for long-term durability.
Double glazing solution
Our double glazing solution retains original window aesthetics through bespoke hardwood sashes with slim double-glazed units. Traditional putty glazing methods ensure identical internal and external appearances, while gas-filled panes and draught-proofing systems deliver modern energy efficiency without compromising historical accuracy.
Draught-proofing installation
We install brush-strip draught-proofing systems within parting beads to eliminate air leakage. This heritage-compliant solution reduces heat loss by up to 70% while maintaining original window operation. The system requires no visible modifications, preserving period character in conservation areas.
Heritage window restoration
Specialist restoration for listed buildings and conservation areas includes traditional carpentry techniques, matching original materials, and reversible modifications. We repair beyond-economic-repair windows using sympathetic replacements that satisfy planning requirements while improving functionality and thermal performance through discreet modern upgrades.
