Timber sash and case windows grace any household with timeless charm. Yet as the years pass, these beautiful windows inevitably need a little additional care and attention.
Sash cords break, draught seals degrade and bottom rails rot through neglect. The window rattles, sticks then does not close properly.

What is a timber sash and case window
The name shows the purpose.
The sash refers to the moving panel of glass itself, whilst the case is the hollow box frame that is built within the wall surrounding 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 run over pulley wheels positioned at the topmost section of the frame.
Lift the lower sash and the counterweights descend on the opposite side, when released allows them to hold the sash securely in place.
Whilst casement windows swing outward on hinges, sash and case windows move smoothly in a vertical direction.
Both sashes operate independently, giving you the freedom to open from the top, the bottom, or both at once. You get brilliant ventilation control throughout your home, and with no panel swinging into the room or out towards the street, it is as practical as it is smart!
When the mechanism is functioning as it ought to, you barely notice it is present.
When the cords break, as they invariably do after years of everyday use, the sash falls and remains in that lowered position or gets increasingly difficult to use.
That is precisely where Woodfellas comes into its own.

Timber sash window services and refurbishment
Not every period sash window calls for the same approach!
Our sash windows team in Sunnyside spends time to understand the precise requirements of your windows before recommending whether repair or full refurbishment is the most suitable course of action for you.
Window draught-proofing
A complete window overhaul is the wise choice when the existing frame is structurally solid yet simply not delivering the goods!
Our professional craftsmen employ joinery techniques sympathetic to traditional windows, upgrading your glazing and fitting comprehensive draught-proofing throughout your premises.
A beautifully restored sash and case window in your Sunnyside home should seem as though it was always meant to be there!
Every installation we undertake is driven by the aim of effortless use, silent fitting and a inviting feel within the area.
Sash cord and weight replacement
Replacing sash cords is the most frequent repair job we are called out for!
When the cords snap, the weights hang uselessly inside the case with absolutely nothing linking them to the sash.
We reach the pocket piece, remove the weights, install fresh sash cords, and set the pulleys accurately.
Our team will thoroughly inspect the overall state of the entire window during every visit, ensuring that nothing is ever overlooked.
Timber repairs
Bottom rails and sills bear the harshest of Sunnyside’s weather conditions conditions.
Where the rot is confined to a specific section of the rail, we carefully remove the affected timber and splice in new sections using carefully matched traditional wood. The repair integrates seamlessly with the surrounding timber, while the remainder of the original window remains completely intact.
We strongly believe there is no reason to sacrifice a window that remains sound simply because an issue affects only a section of it.
Supplying and fitting bespoke sash windows
When a window is beyond economical repair, we manufacture new sash windows to your precise specifications in our workshop and provide and fit them at your premises.
Every replacement window is precision crafted and made to measure in hardwood or treated pine. We carefully match the profile, proportions, and glazing bar pattern of the original.
As wooden window manufacturers based in Sunnyside, we provide and fit new sash and case windows across the region, using premium materials and time-honoured craftsmanship techniques.
Our sash and case window range covers all the way from a single replacement sash to a full new window installation for a listed building.
Double glazing and enhanced security hardware are provided as standard features.
Double glazed sash windows in Sunnyside
Improve your home and daily comfort with double glazed sash and case windows.
Our slim-profile sealed units are made to sit neatly within the original glazing rebate, leaving the sash profile and glazing bar pattern completely unchanged.
From the exterior, the timber window appears identical to the original.
Here is the reason so many property owners throughout Sunnyside are choosing to replace their traditional sash and case windows with double glazing.

Energy efficiency
Our glazing service provides significant energy-efficient gains.
This means lower energy bills as your heating system operates less to maintain a comfortable temperature in your home.
Noise reduction
The reduction of noise is one more benefit that homeowners often notice almost immediately.
Living on a heavily trafficked road or close to a large junction, double glazed sash windows provide a noticeable reduction in the amount of noise that gets through.
Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is stunning, steeped in historical significance.
Preserving the distinctive character of our built heritage is precisely what conservation areas are designed to achieve, and sash and case windows form an integral part of that cherished identity. Rely on Woodfellas to respect that heritage through expert timber window restoration.
If your property falls inside one of these designated areas, or if it holds listed building status, the regulations governing window replacement are specific and must be understood before you proceed with any work.
We have carried out work on conservation area properties for over twenty years.
We are familiar with council expectations, can manage the consent process, and replace windows to satisfy requirements without unnecessary delays.
For a team that is familiar with listed buildings and conservation area work just as closely as they understand the windows themselves, get in touch today to book a complimentary site visit and written quotation.
Sash and case window faults we fix in Sunnyside
Sash slipping down and refusing to stay up
When it comes to sash and case repairs, changing a broken sash cord is the job we encounter most often, 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 deteriorated or was not installed in the first place. A sash and case window suffering from draughts will also often rattle noisily in the wind due to that very same gap!
Draught proofing in a service package deals with all issues in a single visit.
Rotten bottom rail
The bottom rail of the lower sash is the most highly vulnerable 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 spliced in using precisely matched material.
The remainder of the original window remains completely unaltered.
Window stuck shut by paint
A build-up of paint applied to protect the sash from Scotland’s harsh wet climate can cause it to bind tightly to the frame.
We release the sash from its binding, carefully clean every surface, adjust the fit wherever, and return the mechanism to smooth, proper working order once again.
The cords and pulleys are inspected throughout the process, spare you from having to carry out several repair jobs.
Single glazing
Original single-glazed panes allow heat to escape fast and permit street noise to filter straight through. We upgrade to double glazing while keeping unchanged the visible profile of your window at all!
Sash and case windows Sunnyside 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 structurally intact sashes makes refurbishment the sensible choice. You preserve good performance without compromising original character. Where the frame has significantly deteriorated or timber rot is beyond repair, replacement becomes the best solution.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that sit within the existing glazing rebate without widening the sash or changing the glazing bar pattern. From the outside, the window looks exactly as the original did always.
