Timber sash and case windows enhance many a household. With time, however, these distinctive windows will require a little extra care and attention.
Over a period of 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 have been relied on timber sash and case window experts serving Scottish homes across Kilbirnie from our workshop premises for more than two decades!
When a window is beyond redemption, we repair, and even craft custom-made replacements to order.

What is a timber sash and case window
The heading accurately reflects how the system operates.
The sash refers to the moving panel of glass, whilst the case is the empty box frame that is built within the wall surrounding 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 run over pulley wheels positioned at the top of the frame.
The lower sash moves up as the counterweights drop on the opposite side, and once released, they hold the sash firmly in place.
Whilst casement windows swing open outward on hinges, sash and case windows work by sliding vertically instead.
Both sashes work independently, letting you open from the top, the bottom, or both at once. You get precise ventilation control with no panel swinging inward or outward.
When the mechanism is functioning flawlessly, you hardly give it a second thought!
When the cords break, as they invariably do after years of regular use, the sash falls and remains in that lowered position or gets increasingly difficult to use.
That is exactly where Woodfellas is invaluable.

Timber sash window services and refurbishment
Not every classic sash window requires an identical approach.
Our Kilbirnie sash windows team carefully assesses what your windows require in order to determine whether repair or full refurbishment is the best-suited option 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 rewarding course of action.
Our experienced craftsmen use joinery methods specifically suited to traditional windows, improving your glazing and fitting draught-proofing throughout your property.
A carefully restored sash and case window in your Kilbirnie home should feel as though it was always meant to be there!
Easy to operate, quiet within its frame, and welcoming in the space it inhabits. This is the standard we work towards with every individual installation.
Sash cord and weight replacement
Sash cord replacement remains our most frequently performed repair.
When the cords break, the weights remain sitting pointlessly inside the casing with nothing to connect them to the sash.
We reach the pocket piece, take out the existing weights, fit fresh sash cords, and position the pulleys accurately.
Whilst completing the work, our team will always make sure to thoroughly inspect the full state of the window, ensuring that nothing is ever overlooked.
Timber repairs
The bottom rails and sills bear the full force of Kilbirnie’s severe weather conditions.
Where the rot is restricted to part of the rail, we remove the affected timber and splice in 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 are strongly of the opinion that a window which stays fundamentally intact should never be sacrificed simply because one section of it has developed a fault.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer a economical option, we produce brand new sash windows to your specific requirements within our workshop and put in them at your property.
Every single replacement window is expertly crafted and made to measure in either hardwood or treated pine. We apply serious effort to match the profile, proportions and glazing bar pattern of your original windows!
As timber window manufacturers situated in Kilbirnie, we install new sash and case windows across the region, employing premium materials and time-honoured craftsmanship.
Our range of sash and case windows encompasses everything from a single replacement sash through to a full set of new windows for a listed building.
Double glazing and improved security hardware are supplied as default features.
Double glazed sash windows in Kilbirnie
Enhance your home and daily 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 wooden window appears identical to the original.
Here is the explanation why property owners throughout Kilbirnie are choosing to replace their traditional sash and case windows with double glazing.

Energy efficiency
Our glazing service delivers a substantial improvement to your home’s energy efficiency.
This means your heating system works much less to maintain a cosy temperature, which straight away results in lower energy bills for you!
Noise reduction
Sound reduction is another advantage that homeowners observe very quickly.
If your home sits on a busy road or close to a major junction, double glazed sash windows will cut down on noise transmission significantly.
Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is as breathtaking as it is historically significant.
Timber sash and case windows are a defining feature of conservation area character, and preserving them matters enormously! Why protect the soul of your building with expert timber window restoration from Woodfellas?
If your premises lies within these designated areas, or if it has listed building status, the regulations surrounding window replacement are particular and must be clearly understood before you organise any work.
For over twenty years, we have carried out work on properties located in conservation areas.
We understand precisely what the council requires, how to move through the consent process with confidence, and how to restore or renew windows in a manner that satisfies every requirement without unnecessary delays or further correspondence.

Sash and case window faults we fix in Kilbirnie
The sash is falling down and not remaining in the open position.
Repairing broken sash cords is the repair our skilled team undertakes most frequently on sash and case windows, and where the window itself remains in good condition, it is a wonderfully easy task for our professional craftspeople.
Draughts and rattling
The draught seal between the sash and the frame has degraded or was never installed in the first place. A sash and case window that lets in draughts will also often rattle in the wind due to that very same gap.
Having draught-proofing included as part of a service package helps address all concerns at once.
Rotten bottom rail
The bottom rail of the bottom sash is the most vulnerable part of a sash and case window!
Where the decay is confined to a portion of the rail, the damaged timber is carefully removed and new sections are inserted using exactly matched material.
The remainder of the original window remains entirely undisturbed.
Window stuck shut by paint
Years of paint applied to the sash to shield it from Scotland’s damp climate can cause it to become stuck to the frame.
We release the sash from its housing, carefully clean all surfaces, make any required adjustments to ensure a proper fit, and return the mechanism to proper working order.
The cords, pulleys and fittings are inspected at every stage, saving you from having to undertake several repair jobs.
Single glazing
Original single-glazed panes surrender heat rapidly and offer little resistance to external noise. We supply and install double glazing whilst retaining the visible profile of the window entirely.
Sash and case windows Kilbirnie FAQs
Is it better to refurbish sash and case windows or replace them?
Whether refurbishment or replacement is the right path forward depends entirely upon the condition of the existing window structure. If the box frame remains sound and the sashes are structurally intact, refurbishment presents itself as a very sensible choice, delivering a window that performs beautifully 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 much more practical and logical course of action.
Can sash and case windows take double glazing?
Yes. We fit 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 the same to the original.
