Sash window repairs and restoration in Wandsworth
We restore, repair and draught-proof timber sash windows in Wandsworth and in the Tonsleys, Wandsworth Common and the streets toward Southfields. The housing is Victorian terraces, larger houses and mansion flats by the common, and Edwardian streets toward Putney. Wandsworth Council has several conservation areas here, with Article 4 directions on parts of Wandsworth Common.

Wandsworth's windows
The Tonsleys, the grid of streets off Old York Road, are Victorian cottages and terraces with simple two-over-two sashes, small enough that the boxes are tight and paint builds up fast. Around Wandsworth Common the houses are larger, with bays, gables and sashes with finer upper panes, and the mansion flats near the common have long runs of big sashes. Toward Southfields and Putney the Edwardian houses mix sashes with casements and leaded lights. The common faults are the familiar ones: sashes painted shut, broken cords, and rot at the cill. Bays on the larger houses have narrow side sashes that drop when their cords go.
What matters most in Wandsworth
In the Tonsleys, the Victorian cottages have simple two-over-two sashes in tight boxes, and paint builds up quickly until they stick. Here painting means clearing that build-up so the sashes slide again, and keeping the coats thin afterwards.
Around Wandsworth Common the houses grow larger, with bays whose narrow side sashes drop once their cords go, and restoration brings those back into balance along with the usual rot at the cill. The mansion flats near the common have long runs of big sashes, where draught-proofing at the meeting rails makes a real difference across many rooms. Toward Southfields and Putney, sashes share the elevation with casements and leaded lights.
What we do in Wandsworth
Conservation in Wandsworth
Conservation areas here include Old York Road, which takes in the Tonsleys, Wandsworth Town and Wandsworth Common, and parts of the area are covered by Article 4 directions. Our guide to conservation areas and Article 4 directions explains how it works. Check your own address on Wandsworth Council's conservation area and Article 4 map, and we will go through what your windows need at the survey. Where an application does need drawings, we can prepare them. That is separate work and we quote for it.
Common questions
Is my house in the Tonsleys in a conservation area?01
Much of the Tonsleys is within the Old York Road Conservation Area. That makes no difference to repair or draught-proofing. If you want to change the windows, we check the address and advise on whether an application is needed. Small Victorian sashes like those in the Tonsleys respond well to repair: they are light, and the timber is usually better than it looks. Many need re-cording and freeing rather than new timber.
Can you double glaze Victorian sashes near Wandsworth Common?02
Usually, with slimline units in the existing sashes, provided they are deep and sound. On the terraces covered by an Article 4 direction we check what needs permission first. Slim units add weight, so we increase the sash weights and renew the cords at the same time, and fit draught-proofing while the sashes are out.
Do you cover all of Wandsworth?03
Yes: Wandsworth Town, the Tonsleys, Old York Road, Wandsworth Common, Earlsfield, Southfields and East Putney, and on into Battersea and Balham. Send photographs for a free digital survey and we confirm on site before work starts. Mansion flats near the common often suit a block-wide programme agreed with the managing agent.
