Secondary Glazing for Sash Window Homes Properties in Walton, Chesterfield
Owners of a sash window homes in Walton tend to ask us the same question, and the honest answer starts with the fabric: sash rattle, draughts and irreplaceable glass. Around Walton Dam that shows up as keeping leaded lights while eliminating winter cold. 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 S40 continuously — Walton sits within reach of the A61 Sheffield Road, which is also the reason a lot of these calls are about noise.
Installs are room-side only, so scaffolding is never needed and the exterior is untouched.
Every opening is templated on site — we do not price secondary glazing by the square metre.
Thermal figures quoted are whole-window, not centre-pane, which is the honest way to state them.
How we would spec this
| Property type | Sash Window Homes (Georgian to Edwardian) |
|---|---|
| Original glazing | vertical box sashes of every era |
| Dominant problem | sash rattle, draughts and irreplaceable glass |
| Local window stock | leaded casement bays |
| Consent position | No conservation designation recorded for this area, so the choice is technical rather than a consent question. |

A vertical slider mirrors the movement of a box sash, so both sashes still open and the room keeps its original ventilation pattern.
A balanced vertical slider gives you two operable sashes behind the original — with the modern seals the original never had.

Common questions
Can Low-E glass be combined with acoustic laminated?
Yes — most heavy specifications combine both, so you get acoustic gain and thermal gain in the same install.
How is the quote calculated?
We survey and template every opening on site, then quote in writing per opening — no per-square-metre pricing that hides oversize charges.
Is there a warranty?
Yes — 10 years on the manufacture and installation, and a manufacturer's warranty on the glass units.
Can I still open the original window?
Yes — every sliding, hinged and lift-out unit is designed to move clear so you can operate the primary window behind it.
How does this compare to replacement double glazing?
A modern secondary unit with Low-E glass and a 100 mm cavity outperforms most existing sealed double-glazed units — and it works on windows you legally can't replace.
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.
