Misted Double Glazing in Armley — Replacement Sealed Units Made Locally
Armley homeowners know the look well: a window that’s gone permanently cloudy, with a misty film sitting inside the glass that no cleaning will touch. That’s a blown double glazed unit — the seal has failed and moisture is now trapped between the panes. PTF Glass makes the made-to-measure replacement unit that fixes it, manufactured just down the road and supplied for you or your glazier to fit into your existing frame.
Misted Glass in Armley’s Older Housing Stock
Armley is one of inner west Leeds’s older neighbourhoods, with row after row of back-to-backs and through-terraces off Town Street and Theaker Lane, plus the converted properties around Armley Park. A lot of that housing had double glazing retro-fitted into existing openings over the past twenty to thirty years — and retro-fitted units in older frames are precisely the ones now reaching the end of their sealed life. When the perimeter seal goes, the unit blows, and condensation forms inside the glass where you can’t get at it.
The cause is straightforward. A sealed unit relies on a continuous edge bond to keep its gas-filled cavity dry. Years of damp Leeds weather, sunshine and temperature change eventually crack that bond. Moist air seeps in, condenses against the cold inner pane, and leaves the milky haze that marks a failed unit. It can’t be cleaned, dried or re-sealed — it has to be replaced.
Made in Bramley, Supplied to Armley
PTF Glass manufactures in Bramley (LS13 4EN), the neighbouring district just west of Armley — about as local as a glass supplier gets. You send us the sizes of the failed unit, we cut and seal a matched replacement, and you collect it from Bramley at no extra cost or we arrange delivery the short distance into Armley. Because we make the glass ourselves, you get a direct price for the finished unit with no national-chain mark-up.
For terraced and back-to-back homes where windows are often a standard, repeatable size, ordering several blown units together can work out more economical than one at a time — worth mentioning when you get your price.
You Only Replace the Glass — the Frame Stays Put
This matters in Armley’s older terraces, where replacing whole windows can be costly and disruptive: in nearly every case you don’t need to. The frame is usually still doing its job. It’s only the sealed glass unit that has failed, and that’s the single part you replace. A new unit, made to your measurements and matched to your spacer and glass type, fits straight back into the existing frame.
You can fit it yourself, or have a local Armley glazier fit a unit bought from us. Our cost of replacing a double glazed unit guide shows what to expect to pay by size before you commit.
Signs the Unit Has Blown
- A cloudy or misty layer sealed between the panes that won’t wipe off
- Visible water or droplets inside the glass, especially on cold mornings
- A dull, dirty look to the window even straight after cleaning
- A pane that feels colder than the rest of the room, signalling lost gas fill
If the moisture is on the room side of the glass instead — the face you can wipe — that points to ventilation rather than a blown unit. Our condensation in double glazed windows guide helps you tell them apart, and our guide on double glazing that’s wet inside covers the wetter cases.

Frequently Asked Questions
Can you supply units for back-to-back and terraced homes in Armley?
Yes. We make made-to-measure units for any window in Armley’s terraces, back-to-backs and converted properties. Because terraced windows are often a standard size, ordering several blown units at once can be more economical — ask when you get your price.
The misting comes and goes with the weather — is the unit still blown?
Yes. A blown unit often looks worse on cold or humid days and clearer when it’s warm and dry, because the trapped moisture condenses and evaporates inside the sealed cavity. It’s still a failed seal and still needs a replacement unit — the fault doesn’t repair itself.
Do I have to replace the whole window?
No. In nearly all cases the frame is sound and only the glass unit has failed. We make a replacement unit to fit your existing frame, so you avoid the cost and upheaval of a full window replacement.
How quickly can I get my Armley unit?
Standard clear units are usually ready within 7–14 working days for collection from Bramley or delivery into Armley. Toughened or specialist glass may take a little longer.
Do you fit the glass?
No — we supply the made-to-measure unit only. You or your own glazier fit it into the existing frame. Single units generally slot straight in once the beading is removed, and any local Armley glazier can do it if you’d prefer.
