Wooden sash and case windows adorn many a property. As time passes, however, these distinctive windows will require a little extra care and maintenance.
Over time, sash cords snap, draught seals deteriorate, and bottom rails start to rot through prolonged neglect. The window then rattles, sticks, and ultimately fails to close properly.
Woodfellas has spent over 20 years as timber sash and case window specialists, helping Scottish homes across Rutherglen from our workshop.
When a window is irreparable, we restore, and also make bespoke replacement units to measure.

What is a timber sash and case window
The heading explains exactly how it works.
The sash is the sliding glass panel. The case is the empty box frame constructed within the wall around the window opening.
Inside each case sit two weights, one serving an upper sash and one serving the lower. They are suspended on sash cords that pass over pulley wheels fitted into the top of the frame.
The lower sash rises as the counterweights drop on the opposite side, and once released, they keep the sash securely in place.
Whilst casement windows open outwards on hinges, sash and case windows operate by sliding vertically.
With both sashes working separately of one another, you have the ability to open from the top, the bottom, or even both simultaneously. That gives your home outstanding ventilation control, all without any panel moving inward into the room or outward toward the street.
When the system is working as it ought to, you barely give it a second thought.
When the cords break, which they often do after years of wear, the sash falls and stays stuck or becomes very difficult to operate.
That is exactly where Woodfellas can make all the difference.

Timber sash window services and refurbishment
Not every classic sash window requires an identical solution.
Our Rutherglen sash window team meticulously examines your window requirements to determine whether repair or refurbishment is the best solution 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 skilled craftsmen are able to improve your glazing and install draught-proofing throughout your home.
A restored sash and case window in your Rutherglen home should feel as though it was always meant to be there.
Every installation we perform is driven by the goal of effortless functioning, silent installation and a welcoming ambience within the room.
Sash cord and weight replacement
Sash cord replacement remains our most commonly carried out repair.
When the cords break, the weights remain idle inside the case with no connection to the sash.
We access the pocket panel, take out the existing weights, replace with fresh sash cords, and ensure the pulleys are properly aligned and adjusted.
Our team will carefully assess the overall condition of the entire window during each visit, making sure that nothing is ever overlooked.
Timber repairs
Lower rails and sills bear the greatest brunt of Rutherglen’s harsh climatic conditions.
Where rot is confined to part of the rail, we remove the damaged timber and insert new sections using matched traditional timber. The repair blends seamlessly with the surrounding wood, leaving the rest of the original window fully intact.
We strongly believe there is no reason to sacrifice a window that remains sound simply because an issue affects only a portion of it.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer a cost-effective option, we produce brand new sash windows to your precise requirements within our workshop and put in them at your property.
Every replacement window is expertly crafted and tailored to measure in either hardwood or treated pine, with careful attention taken to faithfully mirror the profile, proportions and glazing bar pattern of the original window.
As wooden window manufacturers situated in Rutherglen, we provide and fit new sash and case windows throughout the region, employing premium materials and traditional craftsmanship.
Our collection of sash and case windows covers 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 default features.

Enhance your home and boost your everyday comfort with double glazed sash and case windows.
Our units have a slim sealed design that sits neatly within the original glazing rebate, leaving the sash profile and glazing bar pattern completely unchanged.
From the exterior, the timber window looks identical to the original.
Here is why homeowners across Rutherglen are selecting double glazing for their traditional sash and case windows.

Energy efficiency
Our glazing service delivers a substantial boost to your home’s energy efficiency.
This translates directly into reduced energy expenditure, as your heating system need not work as hard in order to maintain a comfortable temperature throughout your home.

Reduced sound is another benefit that homeowners often notice very quickly.
Double glazed sash windows significantly reduce noise transmission for properties on busy roads or by main junctions.

Sash and case window faults we fix in Rutherglen
The sash not staying in the raised position
Replacing broken sash cords is the repair our skilled team performs most often on sash and case windows, and where the window itself remains in good condition, it is a very easy task for our skilled craftspeople.
Draughts and rattling
The weatherseal between the sash and the frame has degraded or was simply never installed in the first place. When this gap exists, it is also quite common for the sash and case window to rattle noticeably in the wind as a direct result of that same gap.
Having draught-proofing addressed as part of a full service visit helps sort out every issue in a one , pleasing sweep.
Rotten bottom rail
The lowest rail of the bottom sash is the most exposed component of a sash and case window.
Where the decay is limited to a specific portion of the rail, the affected timber is carefully removed and replaced with new sections, joined smoothly using carefully matched material.
The rest of the original window remains completely undisturbed.
Window stuck shut by paint
Years and years of paint layered onto the sash to protect it from Scotland’s relentless wet weather can eventually sealing it firmly to the frame!
We loosen the sash carefully, clean and prepare the surfaces thoroughly, make any required adjustments to the fit, and return the mechanism to proper working order.
The cords, pulleys and fittings are checked throughout the process, spare you from having to undertake several repair jobs.
Single glazing
Original single-glazed panes shed heat fast and let in street noise. We install double glazing whilst maintaining the visible window profile unchanged.
Sash and case windows Rutherglen FAQs
Is it better to refurbish sash and case windows or replace them?
It all depends on the current condition of the window itself. Where the box frame remains sound and the sashes are structurally sound, refurbishment is a practical choice. You retain a window that works efficiently whilst preserving its original character. Where the frame has suffered significant deterioration, or the timber has rotted past repair, replacement becomes the practical solution.
Can sash and case windows take double glazing?
Yes. We use slimline sealed units that sit within the existing glazing rebate without widening the sash or altering the glazing bar pattern. From the outside, the window appears identical to the original.
