Stone mullion glazing in Malin Bridge, Sheffield
Around Malin Bridge tram terminus, Malin Bridge still carries a lot of original glazing — bay sashes. Where those are 17th to 19th century, common in pennine and peak-fringe stone housing the failure mode is predictable: the reveal is deep, uneven and rarely plumb, so nothing off the shelf fits. Malin Bridge is not a conservation area, so the decision is purely technical rather than a consent question. Most enquiries here come from owner-occupiers doing one or two rooms at a time, so we price per opening rather than per house. We cover S6 continuously — Malin Bridge sits within reach of the Ring Road (A61), which is also the reason a lot of these calls are about noise.
What we actually fit
| Window type | chamfered stone mullions dividing narrow vertical lights, deep-set in a thick stone wall (17th to 19th century, common in Pennine and Peak-fringe stone housing) |
|---|---|
| Underlying problem | the reveal is deep, uneven and rarely plumb, so nothing off the shelf fits |
| System we fit | hinged units templated to each light, set into the reveal face |
| Glass specification | Low-E as standard; these buildings are usually driven by cold and damp rather than noise |
| Measurement | we template each light individually because the mullion spacing varies within a single opening on hand-cut stonework |
| Heritage position | the stonework is normally the listed or protected element, so fixings go into the internal lining or a timber sub-frame, never the stone |
What we find on these streets
Hand-cut mullions vary by tens of millimetres within one window, so batch-ordering to a nominal size is the classic failure on these buildings.
Deep reveals hold cold air; sealing at the reveal face rather than deep in the opening keeps the cold pocket outside the room.
Malin Bridge stock is Victorian and Edwardian terraces and the prevailing glazing is bay sashes, which is why stone mullion glazing comes up here so often.
We template each light individually because the mullion spacing varies within a single opening on hand-cut stonework.
Malin Bridge carries no conservation designation, so the specification is decided on performance alone.
Quotes are written, itemised per opening, and hold for 60 days.
Listed-building drawings and specifications are prepared free with the quote where consent is needed.
Cavity depth does more for acoustic performance than glass thickness, and we design for it first.
We survey with a sound level meter where noise is the driver, so the target is a number rather than an impression.

Common questions
Can you fit secondary glazing without drilling the stone?
Yes — we fix into a timber sub-frame or the internal lining. Drilling historic stonework is not something we do.
The mullions are all slightly different widths. Is that a problem?
It is normal on hand-cut stone and it is why we template every light separately rather than ordering to a nominal size.
Will it help with damp in the reveals?
Usually. Reveal damp is condensation from cold surfaces meeting warm room air, and warming the reveal is what stops it.
Can we do one room now and the rest later?
Yes. We template and price per opening, so a later phase is quoted at the same rate — there is no penalty for splitting the work.
Will it get in the way of curtains or blinds?
Rarely. Reveal-fixed units sit inside the existing recess; where the recess is shallow we face-fix and reposition the blind, which we flag at survey rather than on the day.

Stone mullion glazing in Malin Bridge — the short version
The reveal is deep, uneven and rarely plumb, so nothing off the shelf fits. We fit hinged units templated to each light, set into the reveal face with Low-E as standard; these buildings are usually driven by cold and damp rather than noise, templated to your opening. Deep stone reveals get warm enough to stop the damp patching that appears at the reveal corners.
