Sash Window Painting & Restoration

In most cases, yes. Restored sash windows with draught-proofing and secondary glazing can match the thermal performance of modern double-glazed units at a fraction of the cost. In Hampstead conservation areas, uPVC replacements are often prohibited by planning regulations, making professional restoration the only permitted route to improved energy efficiency.

A professionally restored sash window with microporous paint finishes and quality draught-proofing should give fifteen to twenty years of reliable service before requiring attention. The microporous paint system allows moisture to escape from the timber rather than trapping it beneath the surface, dramatically reducing the rot and paint failure cycle.

Yes. We use resin-based timber splice repairs to replace only the decayed sections while preserving the sound original timber. This approach is more cost-effective than full replacement, maintains the authentic proportions and moulding profiles of your windows, and satisfies conservation officer requirements for listed buildings.

Draught-proofing is a standard component of every sash window restoration we carry out. We fit Devonshire-type brush seals into routed channels within the frame rebates. These seals are invisible when the window is closed, do not affect the operation of the sash, and dramatically reduce cold air infiltration and rattling.
