What is a timber sash and case window
The term explains the purpose.
The sash refers to the moveable panel of glass, whilst the case is the hollow box frame that is constructed within the wall around the window opening.
Inside every case sit two weights, one designated for the upper sash and another for the lower. These weights are suspended on sash cords that pass over pulley wheels positioned at the top of the frame.
Raise the lower sash and the weights fall 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 operate independently of one another, meaning you can open the window from the top, the bottom, or both at once. This gives your home outstanding ventilation control without any panel swinging inward into the room or outward towards the street.
When the mechanism is working flawlessly, you barely give it a second thought!
When the cords snap, as they so often do after years of faithful service, the sash falls and remains stubbornly in place or becomes increasingly difficult to operate.
That’s where Woodfellas steps in.

Timber sash window services and refurbishment
Not every classic sash window needs an exact solution.
Our sash windows Aird team thoroughly evaluates what your windows require 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 perform on performance, a complete refurbishment becomes the best and most rewarding course of action.
Our experienced craftsmen use joinery methods specifically suited to traditional windows, upgrading your glazing and fitting draught-proofing throughout your property.
A refurbished sash and case window in your Aird house ought to seem as though it was already perfectly as it should be.
Easy to use, quiet in the frame, and warm in the room. That is the standard we work to each time.
Sash cord and weight replacement
Sash cord replacement is the most frequently completed repair we undertake.
When the cords break, the weights lie idle within the case with no connection binding them to the sash.
We access the pocket piece, remove the existing weights, install fresh sash cords, and position the pulleys precisely.
Whilst undertaking your repair, our experts will make sure to carefully assess the complete condition of your window, ensuring that every detail is carefully examined and nothing is overlooked.
Timber repairs
The bottom rails and sills take the full brunt of Aird’s harsh weather conditions.
Where rot is confined to part of the rail, we take out the damaged timber and splice in new sections using matched traditional timber. The repair blends seamlessly with the surrounding wood, leaving the rest of the original window fully intact.
We hold firmly to the belief that there is simply no reason to replace a window that is still structurally sound simply because one portion of it has developed an issue.

Sash and case window faults we fix in Aird
The sash not staying in the raised position
When it comes to sash and case repairs, changing a broken sash cord is the task we encounter most often, and if the window itself is in good condition, it is a quite straightforward job for our experienced team.
Draughts and rattling
The seal between the sash and the frame has deteriorated or was simply never installed in the first place. When this gap exists, it is also quite common for the sash and case window to shake noticeably in the wind as a direct result of that same opening.
Including draught-proofing within a scheduled service appointment deals with all concerns comprehensively and at the same time.
Rotten bottom rail
The lower rail of the bottom sash is the most vulnerable part of a sash and case window!
Where the rot is limited to a specific section of the rail, we remove the damaged timber and splice in fresh new sections using closely matched material!
The remainder of the original window remains completely undisturbed.
Window stuck shut by paint
Years of paint applied to the sash to shield it from Scotland’s damp climate can make it become stuck to the frame.
We remove the sash from its housing, carefully clean all surfaces, carry out any required adjustments to ensure a proper fit, and restore the mechanism to full working order.
The cords and pulleys are inspected throughout the procedure, saving you several repair visits.
Single glazing
Original single-glazed panes allow heat to escape fast and permit street noise to pass straight through. We replace with double glazing without changing the visible profile of your window at all!
Sash and case windows Aird FAQs
Is it better to refurbish sash and case windows or replace them?
It largely comes down to the condition of the current window structure. Where the box frame remains sound and the sashes retain their structural integrity, refurbishment is an ideal course of action. You preserve a window that performs well whilst retaining its original character entirely. However, where the frame has suffered considerable deterioration or the timber has rotted beyond any reasonable repair, replacement becomes the practical and sensible route forward.
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 altering the glazing bar pattern. From the outside the window looks exactly the same to the original.
