Heritage Slim Double Glazing in Caernarfon
Slim-profile sealed units let you double glaze a period sash or Georgian bar window without fattening the glazing bars.
The case for heritage slim double glazing in Caernarfon is straightforward — hardwood outlasts the alternatives, can be repaired rather than replaced, and holds the character of the building.
What is included
- Compression seals rather than brush pile where the design allows, for a measurably tighter close.
- FSC-certified hardwood with documented chain of custody, available on request for planning submissions.
- Warm-edge spacer bars as standard, which cut the cold bridge at the glass edge and reduce condensation.
- Compression seals rather than brush pile where the design allows, for a measurably tighter close.
A well-made slim glazing in Caernarfon should open with one hand, seal without slamming and need nothing more than a wash and an occasional inspection. That is the standard we work to.
We install across Gwynedd with our own fitting teams and make good internally as part of the price. No sub-contracted surprises.

Questions
Do you repair windows or only replace them?
We repair wherever repair is the right answer. Rot is normally localised in a cill or the bottom of a stile, and splicing in new hardwood is typically a third of the cost of replacement. We will tell you honestly at survey which way the economics fall.
Can you match existing windows?
Yes. That is most of what we do. We record the existing sections at survey, reproduce the mouldings and sightlines, and match the finish. On listed buildings we will produce like-for-like profile drawings for the consent application.
Are hardwood windows secure?
Yes. Multi-point locking, laminated glass options and key-locking handles are all available, and a solid hardwood frame is considerably harder to attack than a hollow plastic one. We can specify to PAS 24 where a planning condition or insurer requires it.
Do you take away the old windows?
Yes. Removal and responsible disposal are included, along with making good internally. We work one opening at a time so the property is never left open, and we clear the site each day.
