Gwynedd is a county of slate-roofed stone cottages in quarrying villages and coastal holiday properties. That is exactly the kind of building stock a sash window restoration 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
We build sash window restoration as cabinetmakers rather than fitters: machined joints, real carcass construction, and a finish applied under workshop conditions before anything reaches your Gwynedd address.
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.

What happens next
Four steps, no surprises
Survey
A joiner visits, measures the opening, checks for level and plumb, and talks through how you want to use the space.
Drawings & quote
You get a setting-out drawing and a fixed written price. Nothing is ordered until you have approved both.
Workshop
Parts are machined, assembled and finished under cover while the site carries on with other trades.
Fit & handover
We fit, scribe, adjust and touch in, then walk you through care and adjustment before we leave.
Straight answers
Sash Window Restoration in Gwynedd — common questions
How do you deal with rot?
We cut the decayed timber out entirely and splice in new — usually Accoya — with a scarfed and glued joint. Filler over rot is a cosmetic fix that fails within two years; we do not do it.
What is involved in overhauling the mechanism?
Ease the sashes, renew the cords, check and rebalance the weights, replace worn pulleys, and refit the beads with new brush seals. Done properly the window runs with one finger and stays where you leave it.
Will draught-proofing alone make a difference?
A significant one. Most of the discomfort from an old sash is air movement, not glass conduction. A full brush-seal overhaul typically cuts the draught to near zero for a fraction of the cost of replacement.
Do you paint them afterwards?
We prepare, prime and can apply the full finish, or leave them primed for your decorator. Repaired areas need the same coating system as the rest for the finish to wear evenly.
Can you match existing joinery in the house?
Yes. We take a profile of the existing skirting, architrave or door and either match it from stock cutters or have a cutter ground so the new work runs identically. Matching an old paint colour is straightforward; matching aged oak takes a sample panel and a couple of attempts, which we build into the programme.
