Misted Double Glazing in Rothwell — Made-to-Measure Replacement Sealed Units
Foggy, hazy glass that you simply can’t wipe clean is the tell-tale sign of a blown double glazed unit, and it’s a problem we see across Rothwell, Oulton and Woodlesford every week. When the seal around a glass unit fails, moisture creeps into the gap between the panes and stays there. PTF Glass makes the made-to-measure replacement unit that puts it right for good — manufactured nearby in Bramley and supplied ready for you or your glazier to fit.
Blown Units Around Rothwell, Oulton & Woodlesford
Rothwell sits between Leeds and Wakefield, and much of its housing dates from the steady estate-building of the 1980s and 1990s — the very generation of double glazing now reaching the end of its sealed-unit life. Properties around Oulton, Woodlesford and the newer developments off the Leeds–Wakefield corridor share the same story: frames that are still perfectly serviceable, but glass units whose edge seals have quietly failed after decades of weather.
A double glazed unit is two panes bonded around a sealed, gas-filled cavity. When the perimeter seal breaks down — through age, UV exposure or constant expansion and contraction — the insulating gas leaks out and damp air gets in. That moisture condenses on the inner glass surfaces, leaving the misty bloom that won’t clean off. No spray, cloth or DIY trick brings it back; the unit has to be replaced.
Local Supply, Straight Down the A61 Corridor
Our manufacturing base in Bramley (LS13 4EN) is an easy run from Rothwell, which means short, practical journeys whether you collect or we deliver. The process is simple: measure your failed unit, send us the width, height, thickness and glass type, and we make a like-for-like replacement. Collect it from Bramley at no extra cost, or ask us for a delivery price into Rothwell when you order.
Because PTF Glass manufactures the units itself, you deal directly with the maker. There’s no national franchise taking a cut, no subcontractor, and no fitter’s day-rate built into the glass price — just the cost of the unit, quoted up front.
The Frame Stays — Only the Glass Is Replaced
It’s worth saying plainly, because it saves Rothwell homeowners a lot of money: a misted window almost never needs a whole new frame. The frame is usually sound. It’s the sealed glass unit inside it that has failed, and that’s the only part you need to replace. A new unit, made to your sizes and matched to your existing spacer and glass type, slots straight back into the frame once the beading is taken out.
You can fit it yourself if you’re handy, or have any Rothwell glazier fit a unit you’ve bought from us. To understand the likely cost before you order, see our guide to the cost of replacing a double glazed unit.
How to Tell a Blown Unit from Ordinary Condensation
Not every misty window is a failed unit. Condensation on the inside face of the glass — the side you can touch — is usually about room humidity and ventilation, and it wipes away. Misting between the panes is different: it’s sealed in and unreachable, and it means the unit has blown. If you’re unsure which you’ve got, our condensation in double glazed windows guide walks through it, and our double glazing wet inside guide covers the watery, dripping cases.
- A permanent foggy or milky haze trapped between the two panes
- Water droplets or tide-marks visible inside the sealed unit
- One pane noticeably colder than the surrounding room
- A cloudy patch that returns no matter how thoroughly you clean

Frequently Asked Questions
Do you supply replacement units to Oulton and Woodlesford as well as Rothwell?
Yes. We make made-to-measure replacement sealed units for the whole Rothwell area, including Oulton, Woodlesford and Robin Hood. Units are manufactured at our Bramley base (LS13 4EN) for free collection, or we can arrange delivery — ask for a price when you order.
My window has water inside the glass — is that the same as misting?
It’s the same underlying fault. Both a foggy haze and visible water droplets inside a unit mean the edge seal has failed and moisture has entered the sealed cavity. The fix is identical: a new factory-sealed unit made to the size of the old one.
How accurate do my measurements need to be?
Precise — a made-to-measure unit has to match the existing glass closely to seat correctly. We’re happy to talk you through exactly how to measure the width, height, overall thickness and glass type when you get in touch, so your replacement is a true like-for-like fit.
Is replacing the unit cheaper than a new window?
Almost always, yes — usually a fraction of the cost. Because the frame stays in place and only the glass unit is replaced, you avoid the expense and disruption of a full window. Our cost guide gives typical figures by unit size.
Do you fit the units in Rothwell?
No — PTF Glass supplies the made-to-measure unit only. You collect it from Bramley or we deliver, and you or your own glazier fit it into the existing frame. Single units usually drop straight in once the beading is removed.
