Cardiff is a county of Victorian bay-fronted terraces on a grid, with steady period refurbishment. That is exactly the kind of building stock a sash window has to be drawn around, so we allow for it at survey stage rather than on fitting day — walls get checked for wind and plumb, floors for level, and the setting-out is taken from the worst reading, not the best.
How we approach it
Off-the-shelf units are made to standard sizes and then filled out with scribe strips. Our sash window work is cut to the dimensions taken from your Cardiff property, so there is no packing, no filler and no gap that opens up in year two.
How we build it
Carcass work is birch ply or MR MDF depending on span and load. Face frames and doors are solid hardwood. Everything is machined on the same setting so stiles, rails and reveals line through, and shadow gaps stay parallel from one end of the run to the other.
Finish and materials
Every finished job gets a short handover: what the surface is, how to clean it, and how to adjust a hinge if a door drops after the heating has been on for a season. Adjustment is normal in timber and takes about two minutes once you know which screw to turn.

Straight answers
Timber Sash Windows in Cardiff — common questions
How draughty will they be?
A new sash with brush seals in the meeting rail, staff bead and parting bead is not draughty at all. The draught in an old sash comes from a worn rebate, not from the design.
Can you match the original glazing bars?
Yes. We match the bar width and profile from the original. With double glazing, a true divided bar with individual small units is the authentic route; a bonded bar with a spacer inside is far cheaper and reads correctly from the street.
Is it cheaper to repair the existing sashes?
Very often, yes — see our sash window restoration service. If the boxes are sound and only the sills and bottom rails have gone, repair is usually the better value and keeps the original glass.
Do I need planning permission or listed building consent?
In a conservation area, replacing windows usually needs permission and the replacement must match the original. In a listed building you will need listed building consent. We can supply drawings and a specification to support an application.
How long does a bespoke job take from order to fitting?
Most fitted furniture runs four to eight weeks from approved drawings to fitting day. Kitchens, staircases and timber windows are longer at eight to fourteen weeks because the components are larger and the finishing schedule is longer. We give you a date band at quotation and confirm the fitting week once the drawings are signed off.
