Timber sash and case windows can really transform any household. But over time, these wonderful windows will need a little extra attention and care!
Over a period of time, sash cords snap, draught seals deteriorate, and bottom rails begin to rot through prolonged neglect. The window then shakes, sticks, and ultimately fails to close properly.
Woodfellas are experts in timber sash and case windows, supporting Scottish homes throughout Cumbernauld from our workshop for more than two decades.
We restore, and manufacture bespoke replacements when a window is beyond saving.

What is a timber sash and case window
The name shows the function.
The sash is the moveable glass panel. The case is the empty box frame built within the wall around the window opening.
Inside each case sit two weights, one serving the upper sash and one serving the lower. They are hung on sash cords that run over pulley wheels fitted into the top of the frame.
Raise the lower sash and the counterweights drop on the opposite side, releasing it allowing them to hold the sash firmly in place.
Whilst casement windows swing open outward on hinges, sash and case windows operate by moving vertically instead.
Both sashes operate independently, allowing you to open from the top, the bottom, or both at once. You have precise ventilation control with no panel swinging inward or outward.
When the mechanism is operating as intended, you scarcely observe it whatsoever.
When the cords break, which they often do after years of wear, the sash drops and remains stuck or becomes extremely difficult to operate.
That is exactly where Woodfellas is invaluable.

Timber sash window services and refurbishment
Not every classic sash window requires an identical approach.
Our sash windows Cumbernauld team carefully listens to understand your window’s requirements before advising whether repair or full refurbishment is the best-suited path forward for you.
Window draught-proofing
When a window remains structurally intact yet does not perform on performance, a complete refurbishment becomes the most sensible and most rewarding course of action.
Using joinery methods that complement traditional windows, our skilled craftsmen are able to upgrade your glazing and install draught-proofing throughout your property.
A carefully restored sash and case window in your Cumbernauld home should seem as though it was always intended to be there!
Effortless to operate, silent within the frame, and inviting in the space. That is the standard we strive towards on every instance.
Sash cord and weight replacement
Sash cord replacement remains our most commonly carried out repair.
When the cords snap, the weights remain sitting uselessly inside the casing with nothing to connect them to the sash.
We reach the pocket piece, take out the weights, install fresh sash cords, and set the pulleys accurately.
Our team will carefully assess the overall state of the entire window during each visit, ensuring that nothing is ever missed.
Timber repairs
Bottom rails and sills bear the full force of Cumbernauld’s brutal weather conditions.
Where the decay is confined to a portion of the rail, the compromised timber is carefully removed and replaced with new sections spliced in using matched traditional wood. The repair integrates seamlessly with the surrounding material, whilst the remainder of the original window is preserved completely intact.
We are strongly of the opinion that a window which stays structurally sound should not be discarded simply because an isolated issue impacts only one section of it.

Sash and case window faults we fix in Cumbernauld
The sash not staying in the raised position
Replacing broken sash cords is the repair our skilled team carries out most frequently on sash and case windows, and where the window itself remains in good condition, it is a wonderfully simple task for our professional craftspeople.
Draughts and rattling
The seal between the sash and the frame has either deteriorated to the point of no longer functioning or was just never installed in the first place. That very same unforgiving gap responsible for the draughts is also to blame when the window begins to vibrate uneasily against the wind.
Draught-proofing completed as part of a service call can help fix all issues in a single visit.
Rotten bottom rail
The bottom rail of the lower sash is the most vulnerable part of a sash and case window.
Where rot is limited to part of the rail, we remove the damaged timber and insert new sections using matched material.
The remainder of the original window stays completely untouched.
Window stuck shut by paint
Decades of paint layered on the sash in an effort to protect it from Scotland’s relentlessly wet weather can cause it to become tightly sealed against the frame.
We loosen the sash carefully, clean and prepare the surfaces thoroughly, make any required adjustments to the fit, and return the mechanism to full working order.
The cords and pulleys are carefully inspected during the work, saving you from facing numerous repair jobs down the line.
Single glazing
Original single-glazed panes lose heat fast and admit street noise. We fit double glazing whilst keeping the visible window profile unchanged.
Sash and case windows Cumbernauld FAQs
Is it better to refurbish sash and case windows or replace them?
If refurbishment or replacement is the best way forward depends entirely upon the condition of the existing window structure. When the box frame remains sound and the sashes are structurally intact, refurbishment presents itself as a thoroughly sensible choice, delivering a window that performs beautifully whilst preserving every last trace of its original character. However, when the frame has deteriorated severely or the timber has rotted beyond any hope of repair, replacement becomes the much more practical and logical course of action.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that sit within the existing glazing rebate without any need to widen the sash or alter the glazing bar pattern. From the outside, the window appears identical to the original.
