Complete sash window restoration for period properties in Hampstead NW3. Preserve your original timber frames, eliminate draughts, and achieve a flawless microporous finish.
In Hampstead's conservation areas, uPVC replacement windows are often prohibited, making professional sash window restoration the only route to weathertight, beautiful timber frames. Our sash window specialists remove each sash completely, splice in new timber sections where rot has taken hold, replace broken cotton sash cords, rebalance lead pulleys and weights, and re-glaze with traditional linseed oil putty. We then apply specialist microporous gloss paints that flex with seasonal timber movement, eliminating the cracking and peeling common with standard oil-based gloss. Draught-proofing brush seals are installed discreetly within the frame rebates, dramatically improving energy efficiency without altering the original character of the window.
