Sash Window Restoration & Painting in Hampstead NW3

Original timber sash windows are one of the defining features of Hampstead's period properties. From the elegant six-over-six Georgian sashes on Church Row to the tall Victorian two-over-two windows along Belsize Avenue, these windows deserve expert care rather than replacement.

Why Restore Rather Than Replace?

Planning regulations in Hampstead NW3 conservation areas frequently prohibit the replacement of original sash windows with modern alternatives. But even where replacement is permitted, restoration is often the better choice. Original windows in NW3 were made from old-growth timber far superior to modern softwood. Properly restored and maintained, they will outlast any UPVC replacement.

Our Sash Window Painting Process

We begin by easing the sashes — many windows in NW3 homes have been painted shut over decades of careless decorating. We strip back to bare timber where paint has built up excessively, renew cracked and missing putty with linseed oil putty, replace broken sash cords, and install unobtrusive brush-pile draught-proofing. Only then do we prime, undercoat, and apply two finish coats of premium exterior eggshell.

Best Paints for Sash Windows

For exterior sash windows on Hampstead's period homes, we recommend Dulux Trade Weathershield Exterior Eggshell or Teknos Futura Aqua 40. Both systems offer exceptional durability, flexibility (crucial as timber expands and contracts seasonally), and UV resistance. For purists, we also work with traditional linseed oil paint from Allback, which is historically authentic and remarkably durable.
