Sash Window Painting and Restoration in Hampstead NW3

Original timber sash windows are one of the most architecturally significant features of Hampstead NW3's Victorian and Edwardian housing stock. Properly maintained, they last indefinitely. Neglected, they become draughty, rotten, and — in conservation areas — an expensive problem when planning authorities refuse uPVC replacements.

The Condition Assessment

Every sash window restoration begins with a careful condition assessment: checking the sash cords, testing the run of the sashes, probing for rot in the sill, jambs, and glazing bars, and testing the paint system for stability. This informs our specification for each window.

Draught-Proofing Sash Windows in NW3

We install Ventrolla-style brush pile draught-proofing as part of every sash window restoration — significantly reducing heat loss and draughts without affecting the appearance or operation of the window. This is particularly valued by NW3 homeowners in older properties with single glazing.

Microporous Paint for Timber

External timber in NW3 must be painted with a microporous paint that allows the wood to breathe while repelling water. We use Teknos Futura Aqua 90 or Sikkens Cetol HLSe — both industry leaders in microporous timber coating technology.
