Services
Draught-Proofing Systems
Our draught-proofing systems eliminate up to 98% of draughts and reduce noise by 40%, using discreet PVC weather-strips and brush piles. This enhances comfort while preserving window aesthetics. Ideal for heritage properties seeking modern efficiency without compromising character.
Double-Glazed Sashes
We install slim-line double-glazed units in timber sashes, reducing heat loss by 75% and improving security. This solution maintains original window frames while offering thermal efficiency and noise reduction, perfect for period properties in conservation areas.
Sash Window Restoration
Specialising in Victorian and Georgian windows, we repair rotten sections, replace sash cords, and restore functionality. Our methods use epoxy resin and hardwood inserts to extend window lifespan while retaining historical authenticity and structural integrity.
Frame Repairs
We repair damaged frames by replacing rotten linings and pulley stiles with treated timber. This prevents full replacements, saving costs while maintaining original window structures. All repairs align with conservation guidelines for listed buildings.
Bespoke Window Manufacturing
Crafting made-to-measure sash and casement windows using traditional mortise-and-tenon joints. Available in sustainable redwood or hardwood, these windows replicate original designs while incorporating modern insulation and security features for enhanced performance.

Steve was always very friendly, professional and helpful. We're delighted with the finished product - the house looks better, feels much warmer and more secure for our 3 young children. We would highly recommend Steve to anyone thinking about replacing their sash windows.

I can highly recommend Stephen and his colleague for the work they did to replace the sashes in our windows. They arrived on time and left everywhere tidy. The draught proofing has made a real difference as promised and the windows now slide without difficult.

I first used Classical sash windows twenty years ago to repair a sash window in the lounge and they delivered a very good service then. Contacted the company this year to replace a window in the kitchen and again very pleased with their service. Always very professional and efficient. High recommend this company.
