Wooden sash and case windows bring any home with timeless charm. Yet as the years pass, these elegant windows inevitably call for a little extra care and attention.
The sash cords break and draught seals wear out while bottom rails begin to rot after years of neglect. The window shakes first, then sticks, then eventually fails to close properly altogether.
Woodfellas have been relied on timber sash and case window experts serving Scottish homes across Busby from our workshop for over two decades!
When a window is beyond repair, we restore, and even craft bespoke replacement units to order.

What is a timber sash and case window
The title describes the purpose.
The sash is the sliding glass panel. The case is the hollow box frame constructed within the wall around the window opening.
Inside each 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.
Lift the lower sash upwards and the weights will drop on the opposite side. Release it and they will keep the sash firmly in place.
Sash and case windows slide vertically, whereas casement windows swing outward on hinges.
Both sashes operate independently, giving you the ability to open from the top, the bottom, or both at once. You get excellent ventilation control throughout your home, and with no panel swinging into the room or out towards the street, it is as useful as it is smart!
When the mechanism is functioning as it should, you barely notice it is there.
When the cords break, as they often do after years of use, the sash falls and stays stuck or becomes hard to operate.
That’s precisely where Woodfellas excel!

Timber sash window services and refurbishment
Not every traditional sash window requires an identical answer.
Our sash windows team in Busby genuinely takes the time to understand exactly what your windows need, so they can recommend whether repair or refurbishment is the right route for you!
Window draught-proofing
A complete window refurbishment is the best-suited course of action when the existing window remains sound yet fails to function to its full potential.
Our experienced craftsmen use traditional joinery techniques to improve your glazing and fit draught-proofing throughout.
A beautifully restored sash and case window in your Busby home should feel as though it was always meant to be there!
Effortless to operate, silent 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 often most completed repair we carry out.
When the cords break, the weights stay inactive within the box, no longer linked to the sash in any way.
We reach the pocket piece, recover the weights, fit fresh sash cords, and position the pulleys with accuracy.
Whilst completing the work, our team will consistently make sure to thoroughly check the full condition of the window, so that absolutely nothing is ever overlooked.
Timber repairs
Bottom rails and sills endure the most severe of Busby’s weather conditions conditiones.
Where the rot is localised to a specific section of the rail, we carefully remove the affected timber and splice in new sections using closely matched traditional wood. The repair blends seamlessly with the surrounding timber, while the remainder of the original window remains completely intact.
We are firmly of the view that a window which remains structurally sound should not be sacrificed simply because an isolated issue impacts only one part of it.

Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is striking, rich in historical significance.
The character of conservation areas is something worth protecting with great care, and sash and case windows form a meaningful part of that architectural identity. Protect the integrity of your property through professional timber window restoration carried out by Woodfellas.
If your property is located within one of these designated areas, or if it holds listed building status, the regulations governing window replacement are specific and need to be understood before any work is commissioned.
For more than twenty years, we have carried out work on properties located within conservation areas.
We understand what the council demands, how to handle the approval process, and how to restore or replace windows in a manner that meets those requirements without unnecessary 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 free site visit and written quotation.
Sash and case window faults we fix in Busby
Sash failing to remain in the raised position
Replacing broken sash cords is the repair our experienced team undertakes most frequently on sash and case windows, and where the window itself remains in good condition, it is a wonderfully easy task for our experienced craftspeople.
Draughts and rattling
The draught seal between the sash and the frame has worn away or was never installed in the initial place. A sash and case window that allows in draughts will also tend to rattle in the wind due to the same gap.
Draught proofing done as part of a service call helps fix all issues in a one visit.
Rotten bottom rail
The bottom rail of the lower sash is the most vulnerable part of a sash and case window.
Where the decay is restricted to a specific portion of the rail, the affected timber is gently taken out and substituted by new sections, joined smoothly using closely matched material.
The remainder of the original window remains completely undisturbed.
Window stuck shut by paint
Years and years of paint layered onto the sash to shield it from Scotland’s relentless wet weather can eventually sealing it firmly to the frame!
We free the sash from its binding, thoroughly clean every surface, refine the fit wherever, and return the mechanism to smooth and proper working order once more.
The cables and pulleys are inspected throughout the process, saving you from many repair jobs later on!
Single glazing
Original single-glazed panes shed heat fast and let in street noise. We fit double glazing whilst keeping the visible window profile unchanged.
Sash and case windows Busby FAQs
Is it better to refurbish sash and case windows or replace them?
So what’s the best answer? It really depends on 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 honestly the more sensible and practical option.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that sit neatly within the existing glazing rebate, requiring no alteration to the sash width or glazing bar arrangement. Viewed from the exterior, the window retains the appearance of the original.
