What is a timber sash and case window
The title explains exactly how it functions.
The sash refers to the moveable panel of glass, whilst the case is the hollow box frame that is constructed within the wall surrounding the window opening.
Housed within each case are two counterweights, one corresponding to the upper sash and one to the lower. These weights are suspended from sash cords that travel over pulley wheels positioned at the topmost section of the frame.
Raise the lower sash and the weights drop down on the opposite side. Let go of it and they hold the sash perfectly in place!
Whilst casement windows open outwards on hinges, sash and case windows work by moving vertically.
Both sashes move independently, giving you the freedom to open from the top, the bottom, or both at once. You enjoy excellent ventilation control throughout your home, and with no panel swinging into the room or out towards the street, it is as practical as it is smart!
When the mechanism is functioning properly, you barely give it a second thought.
When the cords snap, as they inevitably do after years of regular use, the sash drops and remains in that lowered position or becomes increasingly difficult to use.
That is precisely where Woodfellas comes into its own.

Timber sash window services and refurbishment
Not every traditional sash window calls for an identical answer.
Our sash windows Castlehill team thoroughly evaluates what your windows need in order to determine whether repair or full refurbishment is the most suitable option for you.
Window draught-proofing
When a window remains structurally intact yet does not provide best performance, a complete refurbishment is the most logical course of action.
Our professional craftsmen use joinery techniques sympathetic to traditional windows, improving your glazing and fitting comprehensive draught-proofing throughout your property.
A carefully restored sash and case window in your Castlehill home ought to feel as though it could never have been anything other than perfectly as it is.
Every fit we complete is guided by a straightforward aim: smooth use, silent fitting, and a warm feel within the space.
Sash cord and weight replacement
Replacing sash cords stands as the most frequently performed repair in our repertoire.
When the cords break, the weights stay idle within the case with no connection to the sash whatsoever.
We take off the pocket cover, remove the weights, install new sash cords, and adjust the pulleys correctly.
Whilst undertaking the work, our team will always make sure to thoroughly check the full condition of the window, so that absolutely nothing is ever overlooked.
Timber repairs
Bottom rails and sills bear the harshest of Castlehill’s weather conditiones.
Where rot is confined to part of the rail, we remove the damaged timber and insert new sections using matched traditional timber. The repair integrates seamlessly with the surrounding wood, leaving the rest of the original window fully intact.
We are firmly of the opinion that a window which stays fundamentally intact should never be sacrificed simply because one section of it has developed a fault.

Sash and case window faults we fix in Castlehill
The sash failing to remain in the raised position
A broken sash cord is the single most frequent repair we undertake on sash and case windows, and as long as the window itself remains in good condition, it is a perfectly straightforward task for our skilled team.
Draughts and rattling
The weatherstripping seal between the sash and the frame has worn away or was never installed in the first place in the first place. A sash and case window affected by draughts will also tend to rattle when exposed to the wind, owing to that very same gap.
Draught proofing completed as part of a service call can help fix all issues in a one visit.
Rotten bottom rail
The bottom rail of the lower sash represents the most vulnerable part of a sash and case window.
Where rot is confined to part of the rail, we cut out the damaged timber and insert new sections using matched material.
The remainder of the original window remains entirely undisturbed.
Window stuck shut by paint
Years of accumulated paint applied to safeguard the sash against Scotland’s damp climate can make it bond firmly to the frame.
We free the sash, thoroughly clean every surface, carry out any necessary adjustments to the fit, and restore the mechanism to full working order!
The cords and pulleys are fully inspected throughout the work, saving you from numerous repair visits down the line.
Single glazing
Original single-glazed panes are especially inefficient at retaining warmth and offer very little resistance to the intrusion of outside street noise. Our upgrade to double glazing maintains the visible profile of your existing window frames entirely.
Sash and case windows Castlehill FAQs
Is it better to refurbish sash and case windows or replace them?
So what’s the right answer? It really comes down to the condition of the window itself! If the box frame is solid and the sashes are structurally sound, refurbishment is absolutely worth considering. You get excellent performance without sacrificing any of the original character. But if the frame has seriously deteriorated or the timber has rotted beyond saving, replacement is frankly the more sensible and practical option.
Can sash and case windows take double glazing?
Yes! We use slim profile sealed units that fit perfectly within the existing glazing rebate without widening the sash or changing the glazing bar pattern. From the outside the window looks exactly the same to the original.
