03

Every unit we fit is covered by a 5-year guarantee against seal failure and moisture ingress.

What we replace

Sealed units of every shape, size and spec.

Standard

Misted Sealed Units

The classic foggy window. Failed seals trap condensation between the panes — we replace the unit, you keep the frame.

Energy

A-Rated Low-E Glass

Upgrade as you replace. Argon-filled, warm-edge spacer, A-rated for energy efficiency and lower heating bills.

Privacy

Obscure & Patterned

Bathrooms, front doors and side panels — full range of obscure glass patterns, replaced to match.

Repair

Cracked & Broken Glass

Smashed pane or stress crack? We measure, manufacture and refit with minimal disruption.

Decorative

Georgian & Leaded

Bars, lead overlay and stained-glass detail rebuilt into your replacement unit so the look stays the same.

Doors

Door & Conservatory Glass

Composite and uPVC doors, conservatory roofs and side screens — toughened or laminated to spec.

How to spot a failed unit

If the mist is between the panes, the seal has gone.

It's not your heating, it's not the weather. Once the seal fails, moisture is trapped permanently inside the glass — and only a new unit will fix it.

  • 01

    Condensation or droplets inside the glass that won't wipe away.

  • 02

    A milky haze or trapped fog that gets worse on cold mornings.

  • 03

    Limescale-style streaks etched into the inner pane.

  • 04

    Cold draughts near the window when the seal has shrunk back.

  • 05

    Hairline cracks or visible damage to either pane of glass.

Frequently asked

Questions, answered straight.

Do you replace the whole window?
No — and that's the point. The frame is usually perfectly fine. We replace only the sealed glass unit inside it, which is faster, cleaner and a fraction of the cost of a full window.
How long does it take?
Most standard units are swapped in 30–45 minutes. A full house of units is typically done in a single visit.
Will it be warmer afterwards?
Yes. Failed units have lost their insulating gas. New A-rated units with argon fill and warm-edge spacer dramatically reduce heat loss around the glass.
Do you charge for quotes?
No. Call us with rough sizes and we'll give an indicative price on the phone, or arrange a free site measure.
What's the guarantee?
Every replacement unit comes with a 5-year guarantee against seal failure and moisture ingress.
