Timber sash and case windows enhance any home. With time, however, these remarkable windows require a degree of additional care and attention.
Sash cords snap and draught seals wear out while bottom rails gradually rot through years of neglect. The window rattles first, then catches, then simply refuses to close properly!
Woodfellas are specialists in timber sash and case windows, serving Scottish homes throughout Oban from our workshop for over two decades.
We repair , and even craft entirely bespoke replacements when a window is beyond saving!

What is a timber sash and case window
The heading describes the purpose.
The sash refers to the sliding panel of glass, whilst the case is the hollow box frame that is constructed within the wall surrounding the window opening.
Inside each case sit two weights, one serving the upper sash and one serving an lower. They are suspended on sash cords that pass over pulley wheels fitted into the top of the frame.
The lower sash rises as the counterweights drop on the opposite side, and once released, they hold the sash securely held in place.
Whilst casement windows swing outward on hinges, sash and case windows glide smoothly in a vertical direction!
Both sashes operate independently of one another, allowing you to slip open the window from the top, the bottom, or indeed both simultaneously. This provides your home with exceptional ventilation control, entirely without a panel swinging inward into the room or outward towards the street.
When the mechanism operates correctly, you hardly notice it at all.
When the cords snap, as they commonly do after years of everyday use, the sash drops and remains in the position or becomes increasingly difficult to operate.
That is exactly where Woodfellas proves invaluable.

Timber sash window services and refurbishment
Not every classic sash window requires an identical solution.
Our sash windows team in Oban spends time to grasp the precise requirements of your windows before recommending whether repair or full refurbishment is the most suitable course of action for you.
Window draught-proofing
Full window refurbishment works most effectively when the original frame is structurally sound but no longer performing properly.
Our experienced craftsmen apply traditional joinery techniques to enhance your glazing and add draught-proofing throughout.
A carefully restored sash and case window in your Oban home should feel as though it was always meant to be there!
Easy to operate, quiet within its frame, and inviting in the space it inhabits. That is the standard we aim for with every individual installation.
Sash cord and weight replacement
Replacing sash cords is the most frequent repair job we attend for!
When the cords break, the weights stay idle within the case with no connection to the sash whatsoever.
We reach the pocket piece, retrieve the weights, fit fresh sash cords, and align the pulleys with precision.
Our staff will always check the full condition of your window while onsite, so absolutely nothing gets missed!
Timber repairs
Bottom sections and sills bear the greatest brunt of Oban’s harsh climatic conditions.
Where the rot is limited to a portion of the rail, we remove the affected timber and splice in new sections using matching traditional wood. The repair integrates seamlessly with the surrounding timber and the remainder of the original window remains completely intact.
We are firmly of the opinion that a window which remains fundamentally intact should not be sacrificed simply because one section of it has developed a fault.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer a affordable option, we produce brand new sash windows to your specific requirements within our workshop and fit them at your property.
Every replacement window is meticulously and expertly crafted to your exact measurements in either hardwood or treated pine. We take great care to faithfully replicate the profile, proportions, and glazing bar pattern of the original window.
As timber window manufacturers based in Oban, we provide and fit new sash and case windows across the region, using premium materials and time-honoured craftsmanship techniques.
Our collection of sash and case windows covers everything from a single replacement sash through to a complete suite of new windows for a listed building.
Double glazing and enhanced security hardware are included as standard features.
Double glazed sash windows in Oban
Enhance your home and everyday comfort with double glazed sash and case windows.
Our sealed units are slimline sealed units that fit within the original glazing rebate without altering the sash profile or glazing bar pattern.
From the outside, the timber window looks identical to the original.
Here is the reason homeowners across Oban are opting for double glazing for their traditional sash and case windows.

Energy efficiency
Our glazing service delivers a noticeable improvement to your home’s efficiency.
This results in lower energy expenditure, as your heating system need not exert itself as greatly in order to maintain a comfortable temperature throughout your home.
Noise reduction
Reducing sound is an additional benefit property owners notice fast.
Living on a busy road or near a busy intersection, double glazed sash windows reduce noise transmission significantly.

Sash and case window faults we fix in Oban
The sash is dropping down and not remaining in the open position.
A broken sash cord is the single most frequent repair we carry out on sash and case windows, and provided that the window itself remains in good condition, it is a very straightforward task for our experienced team.
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 weakest component of a sash and case window.
Where the decay is limited to a particular section of the rail, we gently remove the compromised timber and splice fresh, perfectly matched material seamlessly into its place.
The rest of the original window remains completely undisturbed.
Window stuck shut by paint
Years worth of paint layered upon the sash in an effort to protect it from Scotland’s relentlessly wet weather can cause it to become firmly sealed against the frame.
We remove the sash from its housing, carefully clean the contact surfaces, adjust the fit where required, and return the mechanism to full working order.
The cords and pulleys are carefully inspected throughout the procedure, sparing you from multiple repair jobs later on.
Single glazing
Original single-glazed panes are particularly inefficient at retaining warmth and provide very little resistance to the intrusion of outside street noise. Our upgrade to double glazing preserves the visible profile of your existing window frames entirely.
Sash and case windows Oban FAQs
Is it better to refurbish sash and case windows or replace them?
Whether refurbishment or replacement is the best path forward depends entirely upon the condition of the existing window structure. When the box frame remains sound and the sashes are structurally intact, refurbishment presents itself as a thoroughly sensible choice, providing a window that performs extremely well whilst preserving every last trace of its original character. However, when the frame has deteriorated severely or the timber has rotted beyond any hope of repair, replacement becomes the far more sensible and logical course of action.
Can sash and case windows take double glazing?
Yes! We fit slim profile sealed units that fit perfectly within the existing glazing rebate without altering the sash or changing the glazing bar pattern. From the outside the window appears exactly the same to the original.
