Southampton Misted Glass Repair specialists — sealed unit replacement
Professional misted glass repair service across Southampton and the wider SO area. Fully guaranteed, locally based, and ready to help today.
Misted double glazing is one of the most common — and most fixable — problems we see in Southampton homes. The city's coastal climate accelerates the issue: sealed units fail when the perimeter seal cracks and the inert argon gas inside escapes, letting moist air condense between the panes. Properties along the Itchen, near the docks, and across the western shore tend to see seal failure earlier than inland Hampshire — often at 12-15 years rather than the typical 20.
The good news is you almost never need to replace the whole window. The frame is usually fine. We replace just the sealed glass unit, keeping your existing frame, hardware, and beading. For most homes across SO14 to SO19 — from Polygon and Bevois Valley to Bitterne, Sholing and Lordswood — a misted unit replacement costs between £60 and £120 depending on size and glass spec, with toughened and triple-glazed units at the upper end.
Restoration Glazing has replaced thousands of misted units across Southampton over the past five years. We measure on the first visit, order the unit to your exact size and glass specification, and return to fit once it's in — typically within 7 working days. Every replacement carries our 12-month workmanship guarantee plus the manufacturer's 5-year guarantee against seal failure.
Why Misted Glass Repair Matters in Southampton
Misted glass repair in Southampton is a specialist service that restores clarity and thermal performance to your double glazed windows. If you've noticed condensation forming between the panes of your windows in Shirley, Bitterne, or anywhere across Southampton, it's a clear sign that the sealed unit has failed. Southampton's maritime climate and proximity to the coast can accelerate seal degradation, meaning misted double glazing in Southampton is a particularly common issue that our team deals with on a daily basis.

Common Misted Glass Issues We See in Southampton Properties
- •Coastal-exposed homes in Woolston, Weston and along the Itchen — early seal failure from salt-air ingress, often within 10-12 years rather than the typical 18-20
- •1990s estates across Lordswood, Mansbridge and Townhill Park — first-generation UPVC sealed units now reaching end-of-life, often with multiple windows misting in the same year
- •South-facing Victorian conversions in Polygon, Bevois Valley and Banister Park — high thermal cycling causes earlier seal stress on units that face the sun all day
- •Modern apartments at Ocean Village, West Quay and Centenary Quay — sealed units that have failed under warranty but the original installer is no longer trading
- •Heritage casements in conservation areas — older slim-profile units (4mm-6mm-4mm) where the seal technology is dated and replacement requires careful matching
Frequently Asked Questions — Misted Glass Repair Southampton
How much does misted glass repair cost in Southampton?
Single sealed unit replacement typically costs £60-£120 depending on size, glass thickness and access. Toughened, laminated, leaded or triple-glazed units cost more. Larger picture windows and bay windows are at the upper end. Get an instant indicative price online or call 023 8001 2328 for a free quote.
Do I have to replace the whole window if it's misted?
Almost never. If your frame is sound, we replace just the sealed glass unit and keep your existing frame, hardware, beading and locks. This is the cheaper, faster, and less disruptive option — typically half the cost of a full window replacement.
How long does it take to fix misted glass in Southampton?
We measure on the first visit (usually within 24-48 hours of your quote), order the unit to your exact specification, and return to fit once it's ready — typically within 7 working days for standard units. Toughened, leaded and bespoke units take 10-14 days.
Can salt air really cause misting in Southampton homes?
Yes — properties within a mile or so of the Solent or the Itchen tend to see sealed units fail earlier than the UK average. The salt accelerates the breakdown of the perimeter sealant, which lets moisture in. We see this pattern consistently across Woolston, Weston and parts of the western shore.
