Timber sash and case windows are suitable for every household. Over time, these distinctive windows require some extra care.
Sash cords break, draught seals degrade and bottom rails decay through neglect. The window rattles, jams then does not close properly.
Woodfellas has been delivering specialist timber sash and case window services to Scottish homes throughout Chryston for more than two decades, all from our dedicated workshop.
When a window is irreparable, we restore, and also make bespoke replacement units to order.

What is a timber sash and case window
The title reflects the function.
The sash refers to the sliding panel of glass, whilst the case is the hollow box frame that is constructed within the wall around the window opening.
Contained within each case are two counterweights, one corresponding to the upper sash and one to the lower. These weights are suspended from sash cords that travel over pulley wheels positioned at the topmost section of the frame.
Lift the lower sash upwards and the weights will drop on the opposite side. Release it and they shall keep the sash firmly in place.
Whilst casement windows open outwards on hinges, sash and case windows operate by sliding vertically instead.
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 barely notice it at all.
When the cords snap, as they so often do after years of reliable service, the sash drops and remains stubbornly in place or becomes increasingly difficult to operate.
That’s where Woodfellas steps in.

Timber sash window services and refurbishment
Each traditional sash window requires its own solution.
Our sash windows team in Chryston takes the time to truly understand the particular requirements of your windows, so that they can confidently recommend whether a repair or a full refurbishment is the best suited course of action for you.
Window draught-proofing
When a window remains structurally intact yet does not provide optimal performance, a complete refurbishment presents itself as the most sensible course of action.
Our skilled craftsmen use traditional joinery techniques well suited to period windows, improving your glazing and installing comprehensive draught-proofing throughout your home.
A carefully restored sash and case window in your Chryston home should seem as though it was always meant to be there!
Easy to open, silent in the frame and warm throughout the room. That is what we are striving for each and every time!
Sash cord and weight replacement
Sash cord replacement is the often most completed repair we undertake.
When the cords break, the weights remain sitting uselessly inside the casing with nothing to connect them to the sash.
We access the pocket piece, take out the existing weights, install fresh sash cords, and set the pulleys precisely.
Our team will always inspect the full condition of the window while on site, so that nothing goes unnoticed.
Timber repairs
Lower rails and sills bear the greatest brunt of Chryston’s harsh climatic conditions.
Where the rot is limited to just one section of the rail, we carefully remove the damaged timber and splice in fresh new sections using perfectly matched traditional wood. The repair blends seamlessly with the surrounding timber and the rest of the original window remains fully intact!
We hold firmly to the belief that there is absolutely no reason to sacrifice a window that remains structurally sound just because one portion of it has developed an issue.
Supplying and fitting bespoke sash windows
When a window is past economical repair, we craft new sash windows to your precise specifications within our workshop and fit them at your property.
Every new window is carefully and skilfully crafted to your exact measurements in either hardwood or treated pine. We carefully ensure to faithfully replicate the profile, proportions, and glazing bar pattern of the original window.
As timber window manufacturers with pride based in Chryston, we provide and fit new sash and case windows across the area, bringing together quality materials with traditional traditional techniques.
Our range of sash and case windows encompasses everything from one single replacement sash all the way to a complete set of new windows for a listed building.
Double glazing and enhanced security hardware are provided as standard features.

Here is the reason so many homeowners across Chryston are choosing to upgrade their traditional sash and case windows with double glazing.

Energy efficiency

Sash and case window faults we fix in Chryston
The sash is failing to stay in the raised position and drops back down.
When it comes to sash and case repairs, changing a broken sash cord is the job we encounter most frequently, and if the window itself is in good condition, it is a quite straightforward job for our experienced team.
Draughts and rattling
The draught seal between the sash and the frame has either worn away or was simply never installed. A sash and case window with draughts will also tend to rattle noisily in the wind due to that very same gap!
Having draught proofing addressed as part of a thorough service visit helps sort out all issues in a one , satisfying sweep.
Rotten bottom rail
The bottom rail of the bottom sash is the most exposed component of a sash and case window.
Where rot is confined to part of the rail, we remove the damaged timber and insert new sections using matched material.
The rest of the original window remains completely unaltered.
Window stuck shut by paint
Years of applying paint to safeguard the sash against Scotland’s damp climate can cause it to become firmly bonded to the frame.
We free the sash, thoroughly clean every surface, carry out any necessary adjustments to the fit, and restore the mechanism to full working order!
The cords and sheaves are inspected during the process, sparing you from many repair jobs down the line!
Single glazing
Original single-glazed panes lose heat quickly and let in street noise. We fit double glazing whilst maintaining the visible window profile unchanged.
Sash and case windows Chryston FAQs
Is it better to refurbish sash and case windows or replace them?
It mainly comes down to the condition of the current 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 reasonable repair, replacement becomes the practical and sensible route forward.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that sit within the existing glazing rebate without any need to widen the sash or alter the glazing bar pattern. From the outside, the window appears identical to the original.
