We were contacted to look at a Period 4 Storey property in North London. The property was situated near to a busy road and Bus route. The customer wanted to restore the period windows to maintain the property’s character and attempt to reduce the noise of the busy road outside. We were contacted after being recommended and visited the property to carry out a survey and prepare a quotation. The customer wanted all the front windows renovated and draught proofed and several windows to the rear. The property had been recently renovated throughout and the only work outstanding was the sash windows.

The sash windows were in various states of decay. Most windows had flaking paint, part rotten sills and general running repairs with broken cords and sashes that failed to fully close. The majority were painted shut and difficult to open. Some did not open at all. One window in particular had so much wood filler it disguised a severe amount of rot. Also the window was undersized for the box and had glass very poorly fitted with exposed edges. All the windows were draughty and rattling.

The whole process and stages were captured on camera to show the full process of repair service we offered. As we are the only Sash repair company to offer a full in house decorating service, the windows were repaired and painted and commissioned as a one stop service. We offer the unique service of painting the entire box whilst the sashes are out. This ensures all the sash window is protected against future weathering.

The sashes were removed and all the repairs undertaken on site by our skilled joiners. This included construction joint repairs, glazing bar repairs and various bottom rail repairs. Sashes were planted with new timbers to increase their size so they could be successfully draught proofed. Some glass was replaced due to poor fitting previously. The house has period stone mullions surrounding the windows. These were fully stripped and prepared for decorating to ensure the finished look was achieved.

The windows after the repairs were completed were preserved, primed and undercoated. The sills were replaced with Iroko and given the same treatment. The sashes were installed with new cords and then draught proofed with a unique Teflon draught proofing to eliminate draughts and rattles. Once the sashes were rebalanced with new heavier lead weights, new locks and lifts were fitted.

The final two top coats were applied to the finished window and all the glass cleaned. The windows were commissioned and the following photographs show all the stages. Photographs labelled before, during and after, The customer was thrilled with the final outcome and had these words to say. Since this work was completed we have been asked to provide a quotation for more windows at the property.

“We were very happy indeed with Mark’s work on our sash windows. He is a perfectionist and the windows were restored back to their former glory – Mark’s attention to detail and commitment to getting a great result was second to none. Mark is also very pleasant to deal with and he leaves the house spotless after he has finished work each day. Highly re
