Misted Double Glazing Repair in Southborough (TN4)
A misted-up window isn't a broken window — the frame is fine, just the sealed glass unit has failed. In Southborough we swap the unit, not the frame: 30–60 min on site, written guarantee, no plaster damage.
Sealed units from £100*
Based in TN1. Typically 12 min to Pembury, 18 min to Tonbridge — most jobs surveyed same week.
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 "misted" actually means
When a double-glazed pane fogs up, the frame is almost always fine. The sealed unit inside the frame — two panes bonded around a perimeter spacer with butyl and secondary sealant — has lost its seal. Modern UPVC, aluminium and composite frames last 25–40 years; the sealed unit inside lasts 15–20. Once that perimeter seal perishes, moisture works into the cavity and condenses on the inside of the glass — that's the haze. The fix is replacing only the sealed unit, leaving the frame alone.

We cover Southborough from a TN1 base — local, nearby, on the road every day.
In Southborough most of the misted-glass calls we take come from sealed-unit failures in the 1985–2010 vintage of double-glazing — the era when the perimeter seals are exactly the right age to perish. The frame is almost always fine; only the sealed unit needs swapping.
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.
That's why we keep made-to-measure spacer-bar colours, glass thicknesses and pattern matches on the van — a Southborough survey rarely throws up a unit we can't replicate.

How much does misted glass repair cost in Southborough?
From £100 per pane. Most jobs land between £120 and £200 depending on size, glass spec and access. A full replacement window in Southborough is typically £400–£800 per window, so swapping the sealed unit saves you £200–£600 per pane. Every quote is written and fixed in advance.
-
How quickly can you reach Southborough?
From our TN1 base we're typically a 10-minute drive to anywhere in Southborough — central streets like London Road are door-to-door inside ten minutes. Same-day surveys most weeks; the actual repair lands within 1–2 weeks of the survey for made-to-measure sealed glass, sooner for stock parts. Call 01892 300511 with your postcode for an honest ETA.

All of TN4. The Southborough streets we cover include Southborough Town Centre, High Brooms, Modest Corner, and Bidborough Ridge — and most of the roads running off them. If your home is in TN4 we've almost certainly been on your road.
-
Do you cover both Southborough and High Brooms?
Yes — together they sit in TN4 and we cover the whole postcode. High Brooms is mostly Victorian terrace with smaller, often patterned sealed units; Southborough proper skews to 1930s and post-war estates with larger casements. The pricing logic is the same: glass swap from £100, hardware from £100, draught-seal repair from £60.
