Wooden sash and case windows grace any household with lasting charm. Yet as the years pass, these beautiful windows inevitably require a little extra care and attention.
Sash cords snap and draught seals degrade while bottom rails gradually rot through years of neglect. The window rattles first, then sticks, then simply refuses to close properly!
Woodfellas has spent over two decades as timber sash and case window specialists, helping Scottish homes throughout Callander from our workshop.
We restore, and make bespoke replacements when a window is beyond saving.

What is a timber sash and case window
The title reflects how the system operates.
The sash is the moveable glass panel. The case is the empty box frame built within the wall around the window opening.
Inside each case sit two weights, one designated for the upper sash and another for the lower. These weights are suspended on sash cords that pass over pulley wheels positioned at the top of the frame.
Raise the lower sash and the counterweights drop on the opposite side, releasing it allowing them to hold the sash firmly in place.
Whilst casement windows swing outward on hinges, sash and case windows glide smoothly in a vertical direction.
Both sashes operate independently, giving you the freedom to open from the top, the bottom, or both at once. You enjoy excellent ventilation control throughout your home, and with no panel swinging into the room or out towards the street, it is as practical as it is smart!
When the mechanism is functioning correctly, you hardly give it a second thought.
When the cords break, as they commonly do after years of everyday use, the sash falls and remains in that position or becomes increasingly hard to operate.
That is precisely where Woodfellas make all the difference.

Timber sash window services and refurbishment
Each traditional sash window demands its own solution.
Our sash windows team in Callander spends time to understand the precise requirements of your windows before advising whether repair or full refurbishment is the most suitable course of action for you.
Window draught-proofing
When a window remains structurally intact yet does not provide optimal performance, a full refurbishment presents itself as the most logical course of action.
Using joinery methods that complement traditional windows, our experienced craftsmen are able to upgrade your glazing and install draught-proofing throughout your home.
A carefully restored sash and case window in your Callander home should feel as though it was always intended to be there!
Effortless to operate, silent within its frame, and welcoming in the space it inhabits. This is the standard we work towards with every single installation.
Sash cord and weight replacement
Sash cord replacement remains the most frequently undertaken repair within our service offering.
When the cords break, the weights stay idle inside the case with no link to the sash.
We open the pocket panel, remove the existing weights, install fresh sash cords, and ensure the pulleys are properly aligned and set.
Our team will thoroughly evaluate the overall condition of the entire window during every visit, ensuring that nothing is ever missed.
Timber repairs
Bottom rail sections and sills bear the impact of Callander’s unforgiving climate.
Where the rot is restricted to part 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 perfectly intact.
We are firmly of the opinion that a window which stays structurally sound should never be sacrificed simply because an isolated issue affects only one part of it.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer cost effective, we craft brand new sash windows to your precise requirements in our workshop and install them at your premises.
Every single replacement window is carefully crafted and made to measure in either hardwood or treated pine. We put in serious effort to replicate the profile, proportions and glazing bar pattern of your original windows!
As timber window manufacturers proudly based in Callander, we provide and fit new sash and case windows throughout the region, bringing together high-quality materials with time-honoured traditional techniques.

Sash and case window faults we fix in Callander
Sash failing to remain in the raised position
Replacing broken sash cords is absolutely the commonest sash and case repair our experienced team tackles, and when the rest of the window is in good condition it is a very easy task for our professional crew!
Draughts and rattling
The draught seal between the sash and the frame has either worn away or was never fitted at all. A sash and case window suffering from draughts will also tend to rattle noisily in the wind due to this very gap!
Having draught proofing dealt with as part of a comprehensive service visit helps sort out all issues in a single , pleasing sweep.
Rotten bottom rail
The bottom rail of the lower sash is the most vulnerable part of a sash and case window.
Where rot is confined to part of the rail, we remove the damaged timber and splice in new sections using matched material.
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 shield it from Scotland’s constantly wet weather can cause it to become tightly sealed against the frame.
We release the sash gently, clean and prepare the surfaces carefully, make any required adjustments to the fit, and return the mechanism to proper working order.
The cords and pulleys are fully inspected throughout the process, sparing you from several repair jobs down the line.
Single glazing
Original single-glazed panes lose heat quickly and let street noise to come through directly. We upgrade to double glazing while keeping unchanged the visible profile of your window at all!
Sash and case windows Callander FAQs
Is it better to refurbish sash and case windows or replace them?
Whether to renovate or replace depends on the window’s existing condition. A sturdy box frame with structurally intact sashes makes refurbishment the sensible choice. You preserve good performance without sacrificing original character. Where the frame has significantly deteriorated or timber rot is irreparable, replacement becomes the more practical solution.
Can sash and case windows take double glazing?
Yes! We use slim profile sealed units that fit perfectly within the existing glazing rebate without altering the sash or altering the glazing bar pattern. From the outside the window appears absolutely identical to the original.
