Timber sash and case windows grace any household. Over time, however, these remarkable windows require a degree of extra care and attention.
Sash cords snap under many years of strain, draught seals wear down through prolonged lack of maintenance, and bottom rails succumb to rot where maintenance has been overlooked. The window begins to rattle, then becomes stiff, and ultimately fails to close as it should.
Woodfellas has been delivering professional timber sash and case window services to Scottish homes across Kilsyth for more than two decades, all from our dedicated workshop.
When restoring and repairs fall short, we create entirely bespoke replacements, forming something new from the very essence of what once was.

What is a timber sash and case window
The title indicates the purpose.
The sash refers to the gliding panel of glass itself, while the case is the empty box frame that is constructed into 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.
The lower sash moves up as the weights fall gracefully on the other side, and once released, they hold the sash securely in place.
Sash and case windows slide vertically, whereas casement windows swing outward on hinges.
With both sashes operating independently of one another, you have the ability to open from the top, the bottom, or even both simultaneously. This gives your home outstanding ventilation control, all without any panel swinging inward into the room or outward toward the street.
When the system is functioning properly, you barely think about it at all.
When the cords eventually break, as they commonly do after years of regular use, the sash will either drop and remain in that lowered position or become increasingly difficult to operate.
That is exactly where Woodfellas steps up.

Timber sash window services and refurbishment
Not every traditional sash window requires an exact solution.
Our sash windows team in Kilsyth takes the time to truly understand the particular needs of your windows, ensuring they can confidently recommend whether a repair or a full refurbishment is the most suitable 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 performing as expected!
Our professional craftsmen employ joinery techniques sympathetic to traditional windows, improving your glazing and fitting comprehensive draught-proofing throughout your premises.
A tastefully restored sash and case window in your Kilsyth property should appear as though it has always been exactly as it was meant to be.
Every fit we perform is guided by the aim of easy use, noise-free fitting and a welcoming ambience within the room.
Sash cord and weight replacement
Replacing sash cords is the most common repair job we attend for!
When the cords snap, the weights hang uselessly inside the case with absolutely nothing linking them to the sash.
We access the pocket piece, remove the weights, fit fresh sash cords, and position the pulleys accurately.
Our team will consistently check the full condition of the window while on site, ensuring nothing goes unnoticed.
Timber repairs
Bottom rails and sills endure the toughest of Kilsyth’s weather conditions.
Where the rot is limited to just one section of the rail, we gently remove the damaged timber and splice in fresh new sections using well-matched traditional wood. The repair sits naturally with the surrounding timber and the rest of the original window remains completely intact!
We are strongly of the opinion that a window which stays fundamentally intact should never be sacrificed simply because one section of it has developed a fault.

Sash and case window faults we fix in Kilsyth
Sash not staying in the raised position
Replacing broken sash cords is absolutely the most frequent sash and case repair our experienced team tackles, and when the rest of the window is in sound condition it is a very straightforward task for our skilled crew!
Draughts and rattling
The seal between the sash and the frame has either deteriorated beyond use or was just never installed in the first place. That very same unrelenting gap responsible for the draughts is also to blame when the window begins to vibrate uneasily against the wind.
Having draught-proofing included as part of a service package helps address all concerns in one go.
Rotten bottom rail
The bottom rail of the lower sash represents the weakest part of a sash and case window.
Where the decay is confined to a portion of the rail, the damaged timber is thoroughly removed and new sections are inserted using exactly matched material.
The remainder of the original window remains entirely undisturbed.
Window stuck shut by paint
A build-up of paint applied to shield the sash from Scotland’s harsh wet climate can cause it to bind tightly 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 return the mechanism to proper working order.
The cords, pulleys and fittings are inspected at every stage, spare you from having to undertake several repair jobs.
Single glazing
Original single-glazed panes surrender heat quickly and provide little resistance to street noise. We fit double glazing whilst preserving the visible profile of the window entirely.
Sash and case windows Kilsyth FAQs
Is it better to refurbish sash and case windows or replace them?
It mainly comes down to the condition of the existing window structure. Where the box frame remains sound and the sashes retain their structural integrity, refurbishment represents an excellent course of action. You preserve a window that performs admirably whilst retaining its original character fully. However, where the frame has suffered significant deterioration or the timber has rotted beyond any practical repair, replacement becomes the more practical and sensible route forward.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that fit neatly within the existing glazing rebate, requiring no alteration to the sash width or glazing bar arrangement. Viewed from the exterior, the window keeps the appearance of the original.
