Draught Sealing Traditional Sash Windows

Our Sash Window Recondition & Draught Seal service will restore your windows to their original functionality, with the benefits of concealed draught excluders. At its core, this is a full sash window overhaul and refurbish service. With the windows dismantled our sash seals are built into the window components becoming practically invisible when the window is reassembled. Sash window draught excluders don’t only stop draughts but also eliminate annoying rattles as well as reducing noise and dust ingress. Low friction sash seals allow sliding sash windows to glide smoothly.

⭐️⭐️⭐️⭐️⭐️ A friend wisely advised us to have one room done first. We were so pleased with the result that we had all the other twelve windows replaced. We live in a conservation area and it was important that the new windows looked exactly the same as the originals. The work was completed so efficiently and so neatly that we cannot recommend Sash Window Specialist highly enough. We survived the cold spells of this winter with our thermostat set several degrees lower than in the past. On stormy days, we no longer have any rattling windows.
