Wooden sash and case windows suit every household. Over time, these distinctive windows require some additional care.
Sash cords snap and draught seals degrade while bottom rails start to rot through years of neglect. The window vibrates first, then sticks, then simply refuses to close properly!
Woodfellas are skilled specialists in timber sash and case windows, serving Scottish homes throughout Denny from our workshop for more than two decades.
When a window is irreparable, we repair, and even produce bespoke replacement units to measure.

What is a timber sash and case window
The title explains the function.
The sash refers to the moveable panel of glass, whilst the case is the empty box frame that is built within the wall around the window opening.
Situated within each case sit two weights, one serving the upper sash and one serving the lower, suspended on sash cords that run over pulley wheels positioned at 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 held in place.
Whilst casement windows open outwards on hinges, sash and case windows work by moving vertically.
Both sashes move independently, giving you the ability to open from the top, the bottom, or both at once. You enjoy excellent 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 clever!
When the mechanism is working flawlessly, you barely give it a second thought!
When the cords snap, as they so often do after years of faithful service, the sash drops and remains persistently in place or becomes progressively difficult to operate.
That’s where Woodfellas steps in.

Timber sash window services and refurbishment
Each traditional sash window requires its own approach.
Our sash windows team in Denny genuinely spends time to understand exactly what your windows need, so they can recommend whether repair or refurbishment is the best route for you!
Window draught-proofing
A complete window refurbishment is the most logical course of action when the existing window remains sound yet fails to function to its full potential.
Our experienced craftsmen apply joinery methods specifically suited to traditional windows, upgrading your glazing and fitting draught-proofing throughout your property.
A sympathetically refurbished sash and case window in your Denny home is likely to feel as though it was always completely and easily destined to be there.
Easy to operate, silent in the frame, and cosy in the room. That is the level we work to each time.
Sash cord and weight replacement
Sash cord replacement is the most frequently carried out repair we undertake.
When the cords snap, the weights lie idle within the case with no connection binding them to the sash.
We access the pocket piece, retrieve the weights, install fresh sash cords, and align the pulleys with accuracy.
Whilst carrying out your repair, our experts will be sure to closely assess the general condition of your window, ensuring that every detail is thoroughly examined and nothing is overlooked.
Timber repairs
Lower sections and sills bear the heaviest brunt of Denny’s severe climatic conditions.
Where the decay is confined to a portion of the rail, the compromised timber is meticulously removed and replaced with new sections inserted using matched traditional wood. The repair blends seamlessly with the surrounding material, whilst the remainder of the original window is preserved entirely intact.
We strongly believe there is absolutely no reason to sacrifice a window that remains perfectly sound simply because an issue affects only a section of it.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer a worthwhile investment, we craft brand new sash windows to your precise specifications within our workshop, then provide and fit them directly at your property.
Every replacement window is expertly crafted and made to measure in hardwood or treated pine. We make every effort to match the profile, proportions, and glazing bar pattern of the original window.
As manufacturers of timber windows proudly rooted in Denny, we craft and install new sash and case windows throughout the region, respecting traditional techniques and sourcing only the highest quality materials.
Our sash and case window selection covers all the way from a single replacement sash to a complete new window installation for a listed building.
Double glazing and enhanced security hardware are provided as standard inclusions.

Energy efficiency
Our glazing service offers a noticeable improvement to your home’s efficiency.
This translates directly into lower energy expenditure, as your heating system need not exert itself as greatly in order to keep a comfortable temperature throughout your home.
Noise reduction
Sound reduction is another advantage that homeowners tend to notice very quickly.
If your property sits on a busy road or near a major junction, double glazed sash windows will cut noise transmission significantly.

Sash and case window faults we fix in Denny
The sash is dropping down and not staying in the open position.
Changing faulty sash cords is the repair our experienced team performs most frequently on sash and case windows, and provided the window is generally in good condition, it is a quite straightforward task for our experienced professionals.
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 admits draughts will also tend to rattle in the wind due to that very same gap.
Having draught-proofing dealt with as part of a thorough service visit helps sort out all issues in a single , satisfying sweep.
Rotten bottom rail
The bottom rail of the bottom sash is the weakest component of a sash and case window.
Where the rot is limited to a specific section of the rail, we take out the damaged timber and splice in new sections using matching material.
The remainder of the original window remains completely undisturbed.
Window stuck shut by paint
Many years of paint layered onto the sash to shield it from Scotland’s relentless wet weather can end up sealing it firmly to the frame!
We release the sash from its binding, carefully clean every surface, refine the fit wherever, and restore the mechanism to smooth, proper working order once again.
The cords and pulleys are checked throughout the procedure, saving you several repair visits.
Single glazing
Original single-glazed panes surrender their warmth with surprising ease and provide little resistance to the clamour of the street beyond. We swap them out with double glazing whilst preserving every detail of the window’s outward appearance completely intact.
Sash and case windows Denny FAQs
Is it better to refurbish sash and case windows or replace them?
Whether refurbishment or replacement is the right approach depends completely upon the existing condition of the window itself. Where the box frame remains structurally sound and the sashes retain their integrity, refurbishment represents a entirely sensible and satisfactory decision, allowing the window to perform with renewed efficiency whilst preserving its original character. However, where the frame has suffered significant deterioration or the timber has decayed beyond the point of viable repair, replacement becomes the more suitable and appropriate course of action.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that fit neatly within the existing glazing rebate, requiring no alteration to the sash width or glazing bar arrangement. Viewed from the exterior, the window retains the appearance of the original.
