Timber sash and case windows grace any home. Over time, however, these remarkable windows require a degree of additional care and attention.
The sash cords break and draught seals deteriorate while bottom rails start to rot through years of neglect. The window rattles first, then jams, then eventually refuses to close properly altogether.
Woodfellas have been committed timber sash and case window specialists, supporting Scottish homes across Alva from our workshop for more than two decades.
We restore and repair, and create bespoke replacements when a window is beyond saving.

What is a timber sash and case window
The title indicates the purpose.
The sash is the sliding glass panel. The case is the empty box frame built within the wall surrounding the window opening.
Housed within each case are two weights, one for the upper sash and one to the lower, both suspended from sash cords that pass over pulley wheels positioned at the top of the frame.
The lower sash moves up as the counterweights drop on the opposite side, and after being released, they hold the sash firmly held in place.
Sash and case windows slide vertically, whereas casement windows open outward on hinges.
Both sashes move independently of one another, meaning you can open them from the top, the bottom, or even both at once. Your home enjoys superb ventilation control without any panel swinging inward into the room or outward towards the street.
When the mechanism is working as it should, you hardly notice it is there.
When the cords snap, as they so frequently do after years of faithful service, the sash drops and remains persistently in place or becomes increasingly difficult to operate.
That’s where Woodfellas comes in.

Timber sash window services and refurbishment
Not every classic sash window needs an identical answer.
Our sash windows team in Alva takes the time to truly appreciate the specific needs of your windows, so that they can recommend with confidence whether a repair or a full refurbishment is the best suited course of action for you.
Window draught-proofing
A complete window overhaul is the smart choice when the existing frame is structurally solid yet just not delivering the goods!
Our experienced craftsmen apply joinery methods specifically suited to traditional windows, improving your glazing and installing draught-proofing throughout your home.
A expertly restored sash and case window in your Alva home ought to feel as though it could never have been anything other than exactly as it is.
Easy to operate, quiet within its frame, and inviting in the space it inhabits. That is the standard we strive towards with every individual installation.
Sash cord and weight replacement
Sash cord replacement is the most popular repair job we are called out for!
When the cords break, the weights hang idle within the case with nothing connecting them to the sash.
We reach the pocket piece, remove the weights, fit fresh sash cords, and set the pulleys accurately.
Our staff will always check the full condition of your window while on site, so absolutely nothing at all gets missed!
Timber repairs
Bottom rail sections and sills bear the impact of Alva’s unforgiving climate.
Where rot is confined to part of the rail, we take out the damaged timber and splice in new sections using matched traditional timber. The repair blends seamlessly with the surrounding wood, leaving the rest of the original window fully intact.
We are strongly of the opinion that a window which remains structurally sound should not be discarded simply because an isolated issue impacts only one part of it.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer a affordable option, we make brand new sash windows to your precise requirements within our workshop and fit them at your property.
Every replacement window is carefully crafted and manufactured to the precise measurements of each opening, available in hardwood or treated pine. We take considerable care to accurately replicate the profile, proportions, and glazing bar arrangement of the original window.
Based in Alva, we manufacture and install new sash and case windows across the area using high-quality materials and traditional techniques.
Our sash and case window range spans everything from a single replacement to a full new window installation for a listed building.
Double glazing and improved security hardware are provided as standard.
Double glazed sash windows in Alva
Improve your home and everyday comfort with double glazed sash and case windows.
Our slim-profile sealed units are made to fit neatly within the original glazing rebate, leaving the sash profile and glazing bar pattern completely unchanged.
From the exterior, the wooden window appears identical to the original.
Here is why property owners throughout Alva are opting for double glazing for their traditional sash and case windows.

Energy efficiency
Our service offers a noticeable improvement to your home’s efficiency.
This means your heating system operates much less to maintain a comfortable temperature, which directly results in lower energy bills for you!
Noise reduction
Sound attenuation is another advantage that homeowners observe very quickly.
Double glazed sash windows substantially minimise noise transmission for properties on busy roads or close to main junctions.
Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is both breathtaking and historically significant.
The character of conservation areas is something worth preserving with care, and sash and case windows form a meaningful part of that architectural identity. Protect the integrity of your property through expert timber window restoration carried out by Woodfellas.
If your property is located within one of these areas, or is a listed building, specific rules apply to window replacement and must be checked before any work is started.
For more than twenty years, we have been working on properties situated within conservation areas.
Having developed a thorough understanding of council expectations, we are well positioned to take you through the consent process and complete window restoration or replacement work that fulfils all requirements efficiently and without needless delays.

Sash and case window faults we fix in Alva
The sash is sliding down and not remaining in the open position.
Replacing broken sash cords is the most frequent sash and case repair we undertake, and on an otherwise intact window it is a straightforward task for our professional team.
Draughts and rattling
The weatherseal between the sash and the frame has worn away or was simply just never installed in the first place. When this gap exists, it is also fairly common for the sash and case window to rattle noticeably in the wind as a direct result of that same opening.
Draught proofing in a service package addresses all issues in one go.
Rotten bottom rail
The bottom rail of the bottom sash represents the most exposed component of a sash and case window.
Where the rot is confined to a particular section of the rail, we remove the damaged timber and splice in fresh new sections using closely matched material!
The rest of the original window is left completely undisturbed.
Window stuck shut by paint
Years of accumulated paint applied to safeguard the sash against Scotland’s damp climate can make it bond firmly to the frame.
We release the sash, clean surfaces, fine-tune the fit where necessary, and restore the mechanism to full operation.
The cords, pulleys and fittings are checked throughout the process, saving you from having to carry out several repair jobs.
Single glazing
Original single-glazed panes are particularly inefficient at retaining warmth and provide very little resistance to the intrusion of external street noise. Our upgrade to double glazing maintains the visible profile of your existing window frames completely.
Sash and case windows Alva FAQs
Is it better to refurbish sash and case windows or replace them?
If refurbishment or replacement is the right way forward depends entirely upon the condition of the existing window structure. When the box frame remains sound and the sashes are structurally intact, refurbishment presents itself as a very sensible choice, delivering a window that performs extremely well whilst preserving every last trace of its original character. However, when the frame has deteriorated severely or the timber has rotted beyond any hope of repair, replacement becomes the far more practical and logical course of action.
Can sash and case windows take double glazing?
Yes. We use slender profile sealed units that fit within the existing glazing rebate without widening the sash or altering the glazing bar pattern. From the outside, the window looks exactly as the original did always.
