Timber sash and case windows grace any household. With time, however, these remarkable windows require a degree of additional care and attention.
The sash cords break and draught seals deteriorate while bottom rails begin to rot through years of neglect. The window rattles first, then sticks, then eventually refuses to close properly altogether.

What is a timber sash and case window
The title indicates the purpose.
The sash refers to the movable glass panel, whilst the case is the hollow timber frame that is constructed 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.
The lower sash moves up as the weights drop gracefully on the opposite side, and once released, they hold the sash perfectly in place.
Whilst casement windows open outwards on hinges, sash and case windows operate by moving vertically.
With both sashes operating independently of one another, you have the freedom to open from the top, the bottom, or even both simultaneously. This gives your home outstanding ventilation control, all without any panel moving inward into the room or outward toward the street.
When the mechanism is functioning as it should, you barely give it a second thought.
When the cords eventually fail, as they commonly do after years of regular use, the sash will either simply drop and remain in that lowered position or become progressively difficult to operate.
That is precisely where Woodfellas can make the difference.

Timber sash window services and refurbishment
Not every classic sash window needs an identical solution.
Our sash windows Carluke team thoroughly evaluates what your windows need in order to determine whether repair or full refurbishment is the most suitable option for you.
Window draught-proofing
Full window refurbishment works best when the original frame is structurally sound but no longer performing properly.
Our experienced craftsmen apply joinery techniques sympathetic to traditional windows, upgrading your glazing and adding comprehensive draught-proofing throughout your premises.
A refurbished sash and case window in your Carluke property ought to seem as though it was always exactly as it should be.
Effortless to operate, silent in the frame, and warm in the room. That is the level we work to each time.
Sash cord and weight replacement
Sash cord replacement is the most commonly performed repair we carry out.
When the cords snap, the weights rest idly within the case with no connection binding them to the sash.
We access the pocket piece, take out the weights, install fresh sash cords, and set the pulleys accurately.
Whilst carrying out your repair, our team will make sure to thoroughly assess the general condition of your window, ensuring that every detail is fully examined and nothing is overlooked.
Timber repairs
Bottom rails and sills endure the harshest of Carluke’s weather conditiones.
Where the rot is restricted to part of the rail, we remove the affected timber and insert new sections using matching traditional wood. The repair blends perfectly with the surrounding timber and the remainder of the original window remains completely intact.
We are firmly of the view that there is no need to sacrifice a window that remains in good structural condition simply because an isolated issue affects only one part of it.

Sash and case window faults we fix in Carluke
The sash is failing to remain in the raised position and drops back down.
Replacing broken sash cords is absolutely the commonest sash and case repair our expert team tackles, and when the rest of the window is in sound condition it is a remarkably straightforward task for our skilled crew!
Draughts and rattling
The weatherstripping seal between the sash and the frame has deteriorated or was never installed in the first place in the first place. A sash and case window afflicted by draughts will likewise tend to rattle when exposed to gusts, owing to this same gap.
Draught proofing within a service package addresses all issues in one go.
Rotten bottom rail
The lower section of the lower sash represents the weakest component 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 entirely undisturbed.
Window stuck shut by paint
Years of paint applied to the sash to protect it from Scotland’s damp climate can cause it to become bonded to the frame.
We free the sash, carefully clean every surface, make any necessary adjustments to the fit, and restore the mechanism to proper working order!
The cords and pulleys are inspected throughout the process, saving you multiple repair visits.
Single glazing
Original single-glazed panes surrender heat quickly and offer little resistance to street noise. We supply and install double glazing whilst preserving the visible profile of the window entirely.
Sash and case windows Carluke FAQs
Is it better to refurbish sash and case windows or replace them?
Whether to refurbish or swap out depends on the window’s existing condition. A sound box frame with structurally intact sashes makes refurbishment the practical choice. You preserve good performance without losing original character. Where the frame has significantly deteriorated or timber rot is beyond repair, replacement becomes the more suitable solution.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that fit within the existing glazing rebate without widening the sash or changing the glazing bar pattern. From the outside, the window looks precisely as the original always did.
