Window Draught & Seal Repair in Southborough (TN4)
Cold air through a closed, locked window? Whistling on windy days? In Southborough we renew the perished rubber gaskets and brush strips — the seal compresses again and the draught is gone. From £60 per window.
Seal repair from £60*
Southborough is the strip of streets either side of the A26 between Tunbridge Wells and the Bidborough turn. Most of the work we do here is on Edwardian and 1930s semis on London Road, Speldhurst Road, Yew Tree Road and the streets running off them — typically 1990s–2000s UPVC sashes in original timber-look frames, with sealed units starting to mist. Plus the post-war estates around Powder Mill Lane and Holden Park, where UPVC casements from a similar vintage are now reaching end-of-seal-life.
High Brooms (slightly north) is largely Victorian terraces and is the part of Southborough with the most stained-glass and leaded-light work — we leave those to the restorers, but we'll handle the misted units behind them. From our TN1 base it is a ten-minute run; we'll usually have a survey slot the same week, often the same day.
Fix what's failed. Don't replace what's working.
What's actually leaking in a "draughty" window
A draughty window almost never means the frame is "gone". It usually means the rubber gasket inside the frame has hardened and lost its compression — so when you close the window, the sash no longer presses against an elastic seal, just a stiff plastic-y strip. UPVC gaskets are typically Q-Lon or bubble-profile rubber; both go hard between 12–25 years depending on UV exposure and frame colour (dark frames cook the rubber faster). The fix is removing the old gasket profile and pressing in new of the same dimension, plus adjusting hinge compression where the hardware has lost tension.

Draught complaints in Southborough cluster around the mid-90s UPVC stock (where the original perimeter gaskets are now 25-plus years old and have lost their squash) and the older timber+UPVC composites where the rubbers have hardened off.
