Timber sash and case windows are suitable for any household. Over time, these distinctive windows require some additional care.
The sash cords break under years of strain, draught seals wear down through prolonged neglect, and bottom rails succumb to rot where maintenance has been overlooked. The window starts rattling, then becomes stiff, and ultimately fails to close as it should.
Woodfellas have been trusted timber sash and case window specialists serving Scottish homes across Culmore from our workshop premises for more than two decades!
When a window is beyond repair, we fix, and also craft bespoke replacement units to measure.

What is a timber sash and case window
The heading describes the purpose.
The sash refers to the sliding panel of glass, whilst the case is the empty box frame that is built within the wall surrounding the window opening.
Inside every case are two weights, one designated for the upper sash and another for the lower. These weights are suspended on sash cords that run over pulley wheels positioned at the top of the frame.
The lower sash moves up as the counterweights descend on the opposite side, and after being released, they hold the sash securely in place.
Whilst casement windows swing open outward on hinges, sash and case windows operate by moving vertically instead.
Both sashes function independently of one another, meaning you can move the window from the top, the bottom, or both at once. This provides your home superb ventilation control without any panel swinging inward into the room or outward towards the street.
When the mechanism operates correctly, you hardly notice it at all.
When the cords break, as they inevitably do after years of regular use, the sash falls and remains in that lowered position or becomes increasingly difficult to operate.
That is precisely where Woodfellas steps up.

Timber sash window services and refurbishment
Not every classic sash window requires an identical solution.
Our sash windows team in Culmore genuinely spends time to understand exactly what your windows need, so they can advise whether repair or refurbishment is the best route for you!
Window draught-proofing
When a window remains structurally intact yet fails to deliver optimal performance, a complete refurbishment is the most logical course of action.
Using carpentry techniques that complement traditional windows, our experienced craftsmen are able to improve your glazing and install draught-proofing throughout your property.
A sensitively restored sash and case window in your Culmore home ought to seem as though it could never have been anything other than perfectly as it is.
Effortless to operate, quiet within its frame, and inviting in the space it inhabits. That is the standard we aim for with every individual installation.
Sash cord and weight replacement
The replacement of sash cords is the most frequently performed repair in our day-to-day work.
When the cords break, the weights rest idly within the case with no connection attaching them to the sash.
We reach the pocket piece, remove the existing weights, install fresh sash cords, and position the pulleys precisely.
Our staff will always inspect the full condition of your window while onsite, so absolutely nothing at all gets missed!
Timber repairs
Bottom rail sections and sills bear the force of Culmore’s severe climate.
Where the decay remains localised to a portion of the rail, the damaged timber is carefully taken out and substituted by splicing in new sections of matched traditional timber. The repair integrates seamlessly with the surrounding wood, whilst the remainder of the original window is preserved entirely intact.
We strongly believe 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 Culmore
Sash not staying in the raised position
Replacing broken sash cords is the repair our skilled team undertakes most frequently on sash and case windows, and where the window itself remains in good condition, it is a wonderfully straightforward task for our professional craftspeople.
Draughts and rattling
The seal between the sash and the frame has deteriorated or was never installed in the first place in the first place. A sash and case window affected by draughts will likewise tend to rattle when exposed to gusts, owing to that very same gap.
Draught proofing as part of a package helps solve all problems at once.
Rotten bottom rail
The bottom section of the lower sash represents the most exposed component of a sash and case window.
Where the decay is limited to a particular section of the rail, we carefully remove the compromised timber and splice fresh, perfectly matched material seamlessly into its place.
The remainder of the original window remains entirely untouched.
Window stuck shut by paint
Many years of paint layered onto the sash to protect it from Scotland’s relentless wet weather can eventually sealing it firmly to the frame!
We loosen the sash gently, clean and prepare the surfaces thoroughly, carry out any required adjustments to the fit, and return the mechanism to proper working order.
The cords and pulleys are fully inspected throughout the process, sparing you from dealing with many repair jobs later on.
Single glazing
Original single-glazed panes lose their warmth with remarkable ease and offer little protection to the clamour of the street outside. We swap them out with double glazing whilst preserving every detail of the window’s outward appearance entirely intact.
Sash and case windows Culmore FAQs
Is it better to refurbish sash and case windows or replace them?
It all depends on the current condition of the window itself. Where the box frame remains sound and the sashes are structurally sound, refurbishment is a sensible choice. You retain a window that performs effectively whilst preserving its original character. Where the frame has suffered serious deterioration, or the timber has rotted beyond the point of repair, replacement becomes the practical solution.
Can sash and case windows take double glazing?
From the outside, the window looks entirely unchanged, as our slim profile sealed units are made to sit neatly within the existing glazing rebate without any need to widen the sash or change the glazing bar pattern.
