Double-Glazed Unit Replacement
Double Glazing Unit Replacement in Cambridge, Huntingdon, Ely & Newmarket
If your windows have started to look misty or cloudy inside the glass, it usually means the sealed unit has failed. The good news is that you often don’t need to replace the whole window, you may need a double glazed unit replacement.
At Clearglass, we specialise in double glazing unit replacement across Cambridge, Huntingdon, Ely and Newmarket, helping homeowners fix misted or damaged windows without the cost of installing brand new frames.
By replacing just the sealed glass unit, we can restore clear windows, improve insulation and make your home feel warmer and more comfortable again.
What Is a Double Glazing Unit Replacement?
A double glazing unit is made from two panes of glass sealed together with a small insulating gap between them. This design helps keep heat inside your home and reduces outside noise.
Over time the seal around the unit can break down. When that happens, moisture gets trapped between the panes and creates the familiar misted or foggy appearance many homeowners notice.
Instead of replacing the entire window, we simply remove the failed glass unit and install a new sealed double glazing unit made to the exact same size. Your existing frame stays in place, which keeps the cost down and the installation quick.
Signs Your Double Glazing May Need Replacing
If you’re noticing any of the following, the sealed unit may have failed:
• Condensation or mist trapped between the glass panes
• Windows that always look cloudy
• Draughts coming from closed windows
• Cracked or damaged glass
• Rooms that feel colder than they used to
Replacing the sealed unit restores the insulation and gets your windows looking clear again.
Why Replace the Sealed Unit Instead of the Whole Window?
In many cases, the window frames are still perfectly good. Replacing the glass unit is usually the simplest and most cost-effective option.
Homeowners often choose this solution because it:
• Costs far less than new windows
• Removes condensation and misting
• Improves energy efficiency
• Reduces outside noise
• Keeps your existing window frames
It’s a straightforward way to improve your windows without the disruption of a full replacement.

Frequently Asked Questions
Can you replace just one pane if only one looks fogged?
In double glazing, if a window has multiple panes of glass, each is a separate unit and therefore each can be replaced separately.
Can the new unit be more efficient than the old one?
Yes. We can upgrade you to A-rated, low-E glass even if your old windows never had it.
Will the new Double-Glazed unit fit the old frame properly?
Absolutely. The glass is manufactured to millimetre-accurate measurements based on your existing frame.
Does replacing the unit weaken the window?
No. The frame remains untouched, and the new unit actually strengthens security, especially if you opt for toughened or laminated glass.
How long does the installation take?
Most window units can be replaced with 30 -60 minutes.
