Sash cords break, draught seals deteriorate and bottom rails rot through neglect. The window rattles, jams then does not close properly.

What is a timber sash and case window
The title shows exactly how it works.
The sash refers to the moveable panel of glass, whilst the case is the hollow box frame that is built within the wall around 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 pass over pulley wheels positioned at the top of the frame.
Lift the lower sash and the weights drop down on the opposite side. Let go of it and they hold the sash perfectly 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 ability to open from the top, the bottom, or both at once. You get excellent ventilation control throughout your home, and with no panel swinging into the room or out towards the street, it is as useful as it is clever!
When the system is working as it ought to, you barely think about it at all.
When the cords eventually break, as they commonly do following years of regular use, the sash will either drop and remain in that lowered position or become progressively difficult to operate.
That is precisely where Woodfellas comes into its own.

Timber sash window services and refurbishment
Not every traditional sash window requires an exact approach.
Our sash windows Paisley team carefully listens to grasp your window’s requirements before recommending whether repair or full refurbishment is the best-suited path forward for you.
Window draught-proofing
When a window remains structurally intact yet does not perform on performance, a complete renovation becomes the most sensible and most worthwhile course of action.
Using carpentry techniques that complement traditional windows, our skilled craftsmen are able to improve your glazing and install draught-proofing throughout your property.
A sympathetically renovated sash and case window in your Paisley home should seem as though it was always perfectly and easily intended to be there.
Effortless to open, silent in the frame and warm throughout the room. That is what we are aiming for every time!
Sash cord and weight replacement
The replacing of sash cords is the most frequently performed repair in our work.
When the cords snap, the weights stay idle within the box, no longer linked to the sash in any manner.
We access the pocket piece, retrieve the weights, fit fresh sash cords, and position the pulleys with accuracy.
Whilst undertaking your repair, our experts will make sure to carefully assess the overall condition of your window, ensuring that every detail is carefully examined and nothing is overlooked.
Timber repairs
Bottom rails and sills withstand the most severe of Paisley’s weather conditions conditions.
Where the rot is restricted to part of the rail, we take out 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 perfectly intact.
We strongly believe to the belief that there is simply no reason to replace a window that remains structurally sound simply because one portion of it has developed an issue.

Sash and case window faults we fix in Paisley
The sash slipping down and refusing to stay up
Changing faulty sash cords is the repair our experienced team performs most often on sash and case windows, and provided the window is otherwise in good condition, it is a perfectly straightforward task for our experienced professionals.
Draughts and rattling
The weatherstripping seal between the sash and the frame has degraded or was never installed in the first place in the first instance. A sash and case window with draughts will equally tend to rattle when exposed to gusts, owing to the same gap.
Incorporating draught-proofing during a scheduled service appointment deals with all concerns thoroughly and simultaneously.
Rotten bottom rail
The lower rail of the lower sash is the most exposed part of a sash and case window!
Where the rot is restricted to a specific section of the rail, we take out the damaged timber and insert new sections using matching material.
The rest of the original window remains entirely undisturbed.
Window stuck shut by paint
Years of using paint to safeguard the sash against Scotland’s damp climate can cause it to become firmly bonded to the frame.
We remove the sash from its housing, thoroughly clean all surfaces, carry out any required adjustments to ensure a proper fit, and restore the mechanism to proper working order.
The cords and pulleys are thoroughly inspected throughout the process, saving you from multiple repair jobs down the line.
Single glazing
Original single-glazed panes lose their warmth with surprising ease and provide little protection to the clamour of the street beyond. We replace them with double glazing whilst preserving every detail of the window’s outward appearance completely intact.
Sash and case windows Paisley 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 solid box frame with sound sashes makes refurbishment the practical choice. You maintain good performance without losing 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 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 retains the appearance of the original.
