Timber sash and case windows are a lovely feature in any home, though as the years roll on, these remarkable windows demand a little extra care and attention.
Sash cords break, the draught seal deteriorates, and the bottom rails begin to rot through years of neglect. The window shakes, then sticks, then eventually fails to close properly.
Woodfellas has been delivering expert timber sash and case window services to Scottish homes across Lenzie for well over two decades, all from our specialist workshop.
When a window is beyond repair, we offer restoration, repairs, and even the crafting of bespoke replacements.

What is a timber sash and case window
The title reflects how the system operates.
The sash is the sliding glass panel. The case is the hollow box frame built within the wall surrounding the window opening.
Nestled within each case sit two weights, one serving the upper sash and one serving the lower, suspended on sash cords that run over pulley wheels positioned at the top of the frame.
Raise the lower sash and the weights drop on the opposite side. Release it and they keep the sash in place.
Sash and case windows move vertically, whereas casement windows swing outward on hinges.
Both sashes glide independently of one another, meaning you can open them from the top, the bottom, or indeed both at once. Your home enjoys superb ventilation control without any panel swinging inward into the room or outward towards the street.
When the mechanism is functioning as it should, you hardly give it a second thought.
When the cords snap, which they often do after years of wear, the sash drops and stays stuck or becomes incredibly difficult to operate.
That is precisely where Woodfellas steps up.

Timber sash window services and refurbishment
Not every traditional sash window calls for an identical answer.
Our sash windows team in Lenzie 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 on performance, a complete renovation becomes the most sensible and most worthwhile course of action.
Our skilled craftsmen use joinery methods specifically suited to traditional windows, upgrading your glazing and fitting draught-proofing throughout your home.
A carefully restored sash and case window in your Lenzie home should feel as though it was always meant to be there!
Effortless to open, silent in the frame and warm throughout the room. That is what we are striving for every time!
Sash cord and weight replacement
Sash cord replacement remains our most frequently performed repair.
When the cords break, the weights remain idle within the box, no more linked to the sash in any manner.
We remove the pocket cover, remove the weights, install new sash cords, and adjust the pulleys correctly.
Our staff will always check the full condition of your window while on site, so completely nothing gets missed!
Timber repairs
The bottom rails and sills take the full force of Lenzie’s severe weather conditions.
Where the decay is confined to a portion of the rail, the compromised timber is meticulously removed and substituted with new sections inserted using matched traditional wood. The repair integrates seamlessly with the surrounding material, whilst the remainder of the original window is preserved entirely intact.
We are strongly of the opinion that there is no need to sacrifice a window that remains in good structural condition simply because an isolated issue affects only one section of it.
Supplying and fitting bespoke sash windows
When a window is beyond economical repair, we make new sash windows to your exact specifications in our workshop and provide and fit them at your premises.
Every replacement window is carefully crafted and custom made in hardwood or treated pine. We take great care to match the profile, proportions, and glazing bar pattern of the original window.

Our range of sash and case windows covers everything from a single replacement sash right through to a full set of brand new windows for a listed building!

Double glazed sash windows in Lenzie
Enhance both the aesthetic appeal and everyday comfort of your home with the classic elegance of double glazed sash and case windows.
Our units feature a slim sealed design that sits neatly within the original glazing rebate, leaving the sash profile and glazing bar pattern completely unchanged.
From the exterior, the wooden window appears identical to the original.
Here is why homeowners across Lenzie are selecting double glazing for their traditional sash and case windows.

Energy efficiency
Our glazing service provides significant energy-efficient gains.
This means your heating system operates much less to keep a cosy temperature, which straight away results in lower energy bills for you!
Noise reduction
The decrease of noise is one more advantage that homeowners often notice nearly immediately.
If your home is located on a bustling road or close to a major junction, double glazed sash windows will cut down on noise transmission substantially.

Sash and case window faults we fix in Lenzie
Sash failing to hold its position when raised
A failed sash cord is the most common repair we carry out on sash and case windows, and provided that the window itself remains in good condition, it is a perfectly straightforward task for our skilled team.
Draughts and rattling
The air seal between the sash and frame has failed or was never installed. A draughty sash and case window will also shake in the wind due to the same gap.
Incorporating draught-proofing during a scheduled service appointment deals with every one of the concerns thoroughly and simultaneously.
Rotten bottom rail
The lower rail of the bottom sash is the most exposed part of a sash and case window!
Where the decay is confined to a particular section of the rail, we gently remove the compromised timber and splice fresh, perfectly matched material seamlessly into its place.
The remainder of the original window remains entirely undisturbed.
Window stuck shut by paint
Many years of accumulated paint applied to protect the sash against Scotland’s damp climate can cause it to bond firmly to the frame.
We release the sash from its housing, carefully clean all surfaces, carry out any required adjustments to ensure a proper fit, and restore the mechanism to proper working order.
The cords, pulleys and fittings are inspected at every stage, saving you from having to undertake several repair jobs.
Single glazing
Original single-glazed panes let heat to escape quickly and permit street noise to pass through. We fit double glazing while maintaining the visible appearance of the window frame entirely.
Sash and case windows Lenzie FAQs
Is it better to refurbish sash and case windows or replace them?
Whether renovation or replacement is the appropriate approach depends entirely upon the existing condition of the window itself. Where the box frame remains structurally sound and the sashes retain their integrity, refurbishment represents a wholly sensible and satisfactory decision, allowing the window to perform with renewed efficiency whilst preserving its original character. However, where the frame has suffered significant deterioration or the timber has decayed beyond the point of viable repair, replacement becomes the more suitable and considered course of action.
Can sash and case windows take double glazing?
From the outside, the window appears entirely unchanged, as our slim profile sealed units are designed to sit neatly within the existing glazing rebate without any need to widen the sash or alter the glazing bar pattern.
