Misted Double Glazing in Headingley — Replacement Sealed Units from PTF Glass
If a window in your Headingley home has fogged up between the panes — a cloudy haze that stubbornly stays put however hard you clean — the sealed glass unit has blown. The seal has failed and moisture is now locked inside the cavity. PTF Glass makes the made-to-measure replacement unit that resolves it permanently, manufactured close by in Bramley and supplied ready for you or your glazier to fit.
Misted Units in Headingley’s Victorian Homes & Bay Windows
Headingley is defined by its handsome Victorian and Edwardian housing — the leafy streets of Far Headingley, the larger semis off Otley Road, and the dense terraces around the cricket ground and student belt. A huge proportion of these homes feature characterful bay windows and tall sash-style openings, often with double glazing fitted into period frames. Those larger feature panes are exactly where blown units show up most, because bigger sealed units carry more stress on their edge seal and tend to fail sooner.
The mechanism is the same whatever the property: a double glazed unit keeps a dry, gas-filled cavity sealed between two panes. When that edge seal degrades with age and weather, the gas escapes and moist air takes its place, condensing on the inner faces of the glass. The result is the misty, unreachable haze that signals a failed unit — and it can only be cured by replacing the glass with a new, factory-sealed unit.
Local Supply into Headingley from Bramley
Our manufacturing base in Bramley (LS13 4EN) is a short drive from Headingley, just across to the west of the city. You measure the failed unit, send us the sizes and glass type, and we manufacture a matched replacement. Collect it from Bramley at no charge, or ask for a delivery price into Headingley when you order. Dealing with the maker directly means a clear price for the finished unit, with no national-chain margin added.
Larger bay and feature panes are heavier and need careful handling, so it’s worth telling us the unit size up front — we’ll factor that into the price and advise on safe collection or delivery.
Keep the Period Frame — Replace Only the Glass
For Headingley’s older homes, this is the key point: a blown unit rarely means a new window. Period and bay frames are often worth keeping, and in almost every case they’re still structurally sound. It’s the sealed glass unit that has failed, and that’s the only part you replace. A new unit, made to your exact measurements and matched to the original glass and spacer, fits back into the existing frame once the beading is removed — preserving the look of the window while restoring its performance.
You can fit it yourself or have a Headingley glazier fit a unit ordered from us. Our cost of replacing a double glazed unit guide sets out typical prices, including for the larger panes common in the area.
How to Spot a Blown Unit
- A milky or foggy haze trapped between the two panes that won’t clean off
- Water droplets or a tide-mark visible inside a bay or feature pane
- A noticeably cold pane where the insulating gas has leaked away
- A persistent dirty appearance even after a thorough clean
If the condensation is on the inner room-side surface — the face you can wipe — that’s more likely a ventilation matter than a blown unit, common in older, less-ventilated rooms. Our condensation in double glazed windows guide explains the difference, and our double glazing wet inside guide covers the wetter symptoms.

Frequently Asked Questions
Can you make replacement units for a Headingley bay window?
Yes. We make made-to-measure units for bay windows and large feature panes, matched to your existing glass and spacer. Larger units are heavier, so we’ll advise on safe collection from Bramley or arrange delivery into Headingley — just give us the sizes when you ask for a price.
Will a new unit change the look of my period window?
No. The replacement is made to match your existing glass type and dimensions and fits the same frame, so the window keeps its original appearance while regaining its clarity and insulation. Only the failed glass unit changes; the frame stays as it is.
One of my panes feels colder than the others — is that related?
It can be. When a unit’s seal fails, the insulating gas leaks out and the pane loses thermal performance, so it can feel colder than neighbouring windows. That’s a sign the unit has blown and a replacement will restore the insulation.
How long does a made-to-measure unit take?
Standard clear units are typically ready within 7–14 working days for collection from Bramley or delivery into Headingley. Larger, toughened or specialist glass can take a little longer.
Do you fit the glass in Headingley?
No — PTF Glass supplies the made-to-measure unit only. You or your own glazier fit it into the existing frame. Any local glazier can fit a unit you’ve ordered from us if you’d rather not do it yourself.
