Wooden sash and case windows suit every household. Over time, these distinctive windows need some additional care.
Sash cords break, the draught seal deteriorates, and the bottom rails begin to rot through years of neglect. The window shakes, then jams, then ultimately fails to close properly.
Woodfellas are experts in timber sash and case windows, supporting Scottish homes across Balloch from our workshop for over two decades.
When restoration and repairs are not enough, we create completely tailored replacements, fashioning a new piece from the very essence of what once was.

What is a timber sash and case window
The heading accurately reflects how the system works.
The sash refers to the movable glass panel, whilst the case is the hollow timber frame that is constructed within the wall around 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.
Lift the lower sash and the weights drop down on the opposite side. Let go of it and they hold the sash perfectly in place!
Sash and case windows move vertically, whereas casement windows open outward on hinges.
Both sashes glide independently of one another, meaning you can open it from the top, the bottom, or indeed 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 is operating properly, you hardly detect it in the least.
When the cords break, as they so often do after years of faithful service, the sash drops and remains persistently 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 requires an identical solution.
Our sash windows team in Balloch 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 full window refurbishment is an appropriate choice when the existing window remains structurally intact yet is failing to perform as it should.
Our expert craftsmen employ traditional joinery techniques ideally suited to period windows, improving your glazing and installing comprehensive draught-proofing across your home.
A beautifully restored sash and case window in your Balloch home should seem as though it was always meant to be there!
Effortless to operate, silent within its frame, and welcoming in the space it inhabits. That is the standard we strive towards with every single installation.
Sash cord and weight replacement
The replacing of sash cords is the most common repair in our services.
When the cords snap, the weights dangle unhelpfully inside the case with nothing at all linking them to the sash.
We access the pocket piece, remove the existing weights, fit fresh sash cords, and position the pulleys accurately.
Our staff will consistently inspect the full state of your window while on site, so completely nothing gets missed!
Timber repairs
Bottom rails and sills bear the greatest brunt of Balloch’s severe climatic 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 blends seamlessly with the surrounding material, whilst the remainder of the original window is preserved entirely intact.
We are strongly of the view that there is no reason to sacrifice a window that remains structurally sound simply because an localised issue affects only one section of it.

Sash and case window faults we fix in Balloch
Sash failing to hold its position when raised
Repairing broken sash cords is the repair our experienced team undertakes most often 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 air seal between the sash and frame has broken down or was never installed. A leaky sash and case window will also rattle in the wind due to the same gap.
Draught proofing as part of a service sorts solve all problems at once.
Rotten bottom rail
The bottom rail of the bottom sash is the most vulnerable component of a sash and case window.
Where the decay is confined 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 is left completely undisturbed.
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 free the sash, thoroughly clean every surface, make any necessary adjustments to the fit, and return the mechanism to proper working order!
The cords and sheaves are inspected throughout the process, saving you from numerous repair jobs later on!
Single glazing
Original single-glazed panes let heat to escape quickly and allow street noise to filter through. We fit double glazing while preserving the visible appearance of the window frame completely.
Sash and case windows Balloch 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 solid and the sashes are structurally sound, refurbishment is a practical choice. You retain a window that works efficiently 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?
Yes. We use slim profile sealed units that sit within the existing glazing rebate without broadening the sash or altering the glazing bar pattern. From the outside, the window looks exactly as the original always did.
