Timber sash and case windows grace many a household. Over time, however, these distinctive windows will demand a little extra care and maintenance.
Sash cords break, the draught seal wears away, and the bottom rails begin to rot through years of neglect. The window shakes, then jams, then eventually fails to close properly.
Woodfellas has been delivering professional timber sash and case window services to Scottish homes across Holytown for well over two decades, all from our specialist workshop.
When a window is beyond saving, we rejuvenate, and even create fully custom replacements to order.

What is a timber sash and case window
The title reflects the purpose.
The sash refers to the sliding panel of glass itself, whilst the case is the hollow box frame that is built within the wall surrounding the window opening.
Inside every case sit two weights, one supporting the upper sash and one supporting the lower. These are suspended from sash cords that run over pulley wheels positioned at the top of the frame.
The lower sash rises as the weights fall gracefully on the other side, and when released, they hold the sash securely in place.
Whilst casement windows swing outward on hinges, sash and case windows glide smoothly in a vertical direction!
Both sashes move independently of one another, meaning you can open them from the top, the bottom, or even both at once. Your home benefits from superb ventilation control without any panel swinging inward into the room or outward towards the street.
When the mechanism functions properly, you hardly notice it at all.
When the cords snap, as they often do with years of use, the sash drops and remains stuck or becomes difficult to operate.
That is exactly the point at which Woodfellas make their entrance.

Timber sash window services and refurbishment
Not every period sash window calls for the same solution!
Our sash windows Holytown team carefully listens to understand your window’s requirements before recommending whether restoration or full refurbishment is the most suitable path forward for you.
Window draught-proofing
A complete window refurbishment is the most logical option when the existing window remains structurally intact yet does not manage to function to its full potential.
Our expert craftsmen employ traditional joinery techniques perfectly suited to period windows, improving your glazing and fitting comprehensive draught-proofing across your home.
A tastefully restored sash and case window in your Holytown property should feel as though it has always been exactly as it was meant to be.
Effortless to operate, silent within the frame, and welcoming in the space. That is the standard we aim towards on every instance.
Sash cord and weight replacement
Sash cord replacement is the most popular repair job we get called out for!
When the cords snap, the weights dangle unhelpfully inside the case with absolutely nothing linking them to the sash.
We reach the pocket piece, remove the weights, fit fresh sash cords, and position the pulleys accurately.
Our team will consistently assess the full condition of the window while on site, so that nothing goes unnoticed.
Timber repairs
Bottom rails and sills withstand the most severe of Holytown’s weather conditions.
Where the rot is confined to a particular section of the rail, we remove carefully the affected timber and splice in new sections using carefully matched traditional wood. The repair integrates seamlessly with the surrounding timber, while the remainder of the original window remains completely intact.
We are firmly of the view that there is no need to sacrifice a window that remains in good structural condition simply because an localised issue affects only one part of it.

Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is breathtaking, with a deeply fascinating historical legacy.
Conservation areas safeguard local character, and sash and case windows make up a vital part of that heritage. Maintain your building’s character through expert timber window restoration by Woodfellas.
Should your property fall within one of these designated areas, or indeed hold listed building status, the regulations governing window replacement are specific and have significant weight prior to starting any works.
For more than twenty years, we have been working on properties located in conservation areas.
We know what the council demands, how to manage the approval process, and how to restore or replace windows in a manner that satisfies those requirements without needless delays or revisions.
For a team that is familiar with listed buildings and conservation area work just as closely as they understand the windows themselves, get in touch today to arrange a complimentary site visit and written quotation.
Sash and case window faults we fix in Holytown
The sash is falling down and not staying in the open position.
Replacing broken sash cords is absolutely the commonest sash and case repair our experienced team tackles, and when the rest of the window is in good condition it is a remarkably simple task for our experienced crew!
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 rattle noticeably in the wind as a direct result of that same opening.
Draught-proofing carried out as part of a service call helps fix all issues in a one visit.
Rotten bottom rail
The bottom rail of the bottom sash is the most vulnerable component of a sash and case window.
Where rot is limited to part of the rail, we cut out the damaged timber and insert new sections using matched material.
The remainder of the original window is left entirely untouched.
Window stuck shut by paint
Years and years of paint layered onto the sash to shield it from Scotland’s persistent wet weather can end up sealing it firmly to the frame!
We release the sash gently, prepare the surfaces thoroughly, carry out any required adjustments to the fit, and restore the mechanism to proper working order.
The cords and sheaves are checked throughout the process, saving you from many repair jobs down the line!
Single glazing
Original single-glazed panes surrender their warmth with surprising ease and provide little resistance to the clamour of the street outside. We swap them out with double glazing whilst retaining every detail of the window’s outward appearance entirely intact.
Sash and case windows Holytown FAQs
Is it better to refurbish sash and case windows or replace them?
Whether to restore or swap out depends on the window’s existing condition. A sturdy box frame with fully intact sashes makes refurbishment the best choice. You maintain good performance without sacrificing original character. Where the frame has badly deteriorated or timber rot is too extensive to repair, replacement becomes the more practical solution.
Can sash and case windows take double glazing?
Yes! We fit slim profile sealed units that sit neatly within the existing glazing rebate without widening the sash or changing the glazing bar pattern. From the outside the window appears exactly the same to the original.
