Timber sash and case windows grace any home. With time, however, these remarkable windows require a degree of additional care and attention.
The sash cords break and draught seals degrade while bottom rails begin to rot through years of neglect. The window rattles first, then sticks, then eventually refuses to close properly altogether.
Woodfellas are specialists in timber sash and case windows, supporting Scottish homes throughout Blantyre from our workshop for over two decades.
When a window is beyond saving, we repair, and even craft entirely bespoke replacements to order.

What is a timber sash and case window
The heading reflects how the system operates.
The sash refers to the sliding panel of glass itself, while the case is the hollow box frame that is constructed into the wall surrounding 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.
Raise the lower sash and the weights drop down on the opposite side. Release it and they hold the sash perfectly in place!
Whilst casement windows swing outward on hinges, sash and case windows glide smoothly in a upward and downward direction.
Both sashes work independently of one another, meaning you can move the window from the top, the bottom, or both together. This provides your home superb ventilation control without any panel swinging inward into the room or outward towards the street.
When the mechanism is working as it should, you hardly give it a second thought.
When the cords break, as they so frequently do after years of faithful service, the sash drops and remains stubbornly in place or becomes increasingly difficult to operate.
That is precisely where Woodfellas comes into its own.

Timber sash window services and refurbishment
Not every classic sash window calls for an exact solution.
Our sash windows team in Blantyre takes the time to grasp the precise requirements of your windows before advising whether repair or full refurbishment is the best suited course of action for you.
Window draught-proofing
A full window overhaul is the smart move when the existing frame is structurally solid yet just not delivering the goods!
Using carpentry techniques that complement traditional windows, our skilled craftsmen are able to improve your glazing and fit draught-proofing throughout your property.
A beautifully restored sash and case window in your Blantyre home should feel as though it was always meant to be there!
Effortless to use, silent in the frame, and cosy in the room. That is the level we work to each time.
Sash cord and weight replacement
Sash cord replacement remains our most commonly carried out repair within the services we offer.
When the cords snap, the weights remain idle within the case with not any connection to the sash at all.
We reach the pocket piece, take out the weights, fit fresh sash cords, and set the pulleys accurately.
Our team will thoroughly evaluate the overall state of the entire window during every visit, making sure that nothing is ever overlooked.
Timber repairs
The bottom rails and sills take the full brunt of Blantyre’s severe weather conditions.
Where the rot is confined to a particular section of the rail, we carefully remove the affected timber and fit 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 think there is no need to replace a structurally sound window over a fault that affects only a section of it.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer a worthwhile investment, we make brand new sash windows to your precise specifications within our workshop, then supply and install them directly at your premises.
Every replacement window is carefully crafted and manufactured to the precise measurements of each opening, available in hardwood or treated pine. We take considerable care to accurately replicate the profile, proportions, and glazing bar arrangement of the original window.
As manufacturers of timber windows firmly rooted in Blantyre, we make and fit new sash and case windows across the region, honouring traditional techniques and sourcing only the highest quality materials.
Our collection of sash and case windows covers everything from one single replacement sash all the way to a complete set of new windows for a listed building.
Double glazing and enhanced security hardware are provided as standard features.
Double glazed sash windows in Blantyre
Enhance your home and everyday comfort with double glazed sash and case windows.
Our sealed units are slim-profile sealed units that sit comfortably within the original glazing rebate, requiring no alteration to the sash profile or the glazing bar pattern.
From the exterior, the timber window appears identical to the original.
Here is why so many property owners across Blantyre are choosing to improve their traditional sash and case windows with double glazing.

Energy efficiency
Our glazing service provides a substantial boost to your home’s energy efficiency.
This means you’ll see a real decrease in your energy bills, since your heating system won’t need to work as hard to maintain a comfortable indoor temperature throughout your home.
Noise reduction
The decrease of noise is another benefit that homeowners often notice nearly immediately.
Living on a busy road or near a busy intersection, double glazed sash windows reduce noise transmission significantly.
Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is both breathtaking and historically significant.
These areas are established to preserve that distinctive character, and sash and case windows form a vital part of it. Protect the character of your home with expert timber window restoration carried out by Woodfellas.
If your property falls within one of these zones, or happens to be a listed building, the regulations surrounding window replacement are precise and absolutely worth understanding before you organise any work!
We have completed work on conservation area properties for over twenty years.
We know what the council requires, how to handle 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 knows listed buildings and conservation area work as well as they understand the windows themselves, get in touch today for a complimentary site visit and written quote.
Sash and case window faults we fix in Blantyre
Sash not holding its position when raised
When it comes to sash and case repairs, changing a broken sash cord is the job we encounter most frequently, and provided the window itself is in good condition, it is a perfectly straightforward job for our experienced team.
Draughts and rattling
The seal between the sash and the frame has either degraded beyond use or was just never installed in the first place. That same unforgiving gap responsible for the draughts is also to blame when the window begins to vibrate fretfully against the wind.
Having draught-proofing included as part of a service package can help address all concerns at once.
Rotten bottom rail
The lower rail of the lower sash is the most exposed 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 is left completely undisturbed.
Window stuck shut by paint
Years of paint applied to the sash to shield it from Scotland’s damp climate can make it become stuck to the frame.
We loosen the sash carefully, prepare the surfaces carefully, carry out any required adjustments to the fit, and return the mechanism to proper working order.
The cords and pulleys are carefully inspected throughout the work, saving you from many repair visits down the line.
Single glazing
Original single-glazed panes shed heat quickly and admit street noise. We install double glazing whilst maintaining the visible window profile unchanged.
Sash and case windows Blantyre FAQs
Is it better to refurbish sash and case windows or replace them?
Whether to refurbish or replace depends on the window’s existing condition. A sound box frame with fully intact sashes makes refurbishment the practical choice. You preserve 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 use slimline sealed units that sit within the existing glazing rebate without widening the sash or altering the glazing bar pattern. From the outside, the window looks identical to the original.
