Timber sash and case windows can really transform any household. But over time, these wonderful windows will need a little extra care and care!
Sash cords break, draught seals degrade and bottom rails rot through neglect. The window rattles, jams then does not close properly.
Woodfellas have been committed timber sash and case window specialists, supporting Scottish homes across Riverside from our workshop for more than two decades.
When restoring and repairs fall short, we craft completely tailored replacements, forming something new from the very soul of what once was.

What is a timber sash and case window
The title explains exactly how it works.
The sash refers to the moveable panel of glass itself, while the case is the empty box frame that is constructed into the wall surrounding 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.
Lift the lower sash and the weights fall down on the opposite side. Release it and they hold the sash perfectly in place!
Whilst casement windows swing outward on hinges, sash and case windows glide gracefully in a vertical direction.
Both sashes move independently of one another, meaning you can open them from the top, the bottom, or even both at once. Your home benefits from superb ventilation control without any panel swinging inward into the room or outward towards the street.
When the mechanism is working perfectly, you barely think about it twice!
When the cords eventually break, as they commonly do after years of regular use, the sash will either drop and remain in that lowered position or become progressively difficult to operate.
That’s where Woodfellas comes in.

Timber sash window services and refurbishment
Not every classic sash window requires an exact approach.
Our Riverside sash windows team carefully evaluates what your windows need in order to determine whether repairs or full refurbishment is the best-suited option for you.
Window draught-proofing
When a window remains structurally intact yet fails to deliver optimal performance, a complete refurbishment is the most sensible course of action.
Our professional craftsmen use traditional joinery techniques to upgrade your glazing and install draught-proofing throughout.
A carefully restored sash and case window in your Riverside home should seem as though it could never have been anything other than perfectly as it is.
Every fit we complete is guided by one simple ambition: effortless operation, low-noise fitting, and a genuinely warm presence within the space.
Sash cord and weight replacement
Sash cord replacement remains our most commonly carried out repair.
When the cords snap, the weights remain idle within the case with no connection to the sash.
We open the pocket piece, remove the weights, attach new sash cords, and align the pulleys accurately.
Our staff will always check the full condition of your window while onsite, so completely nothing gets missed!
Timber repairs
Lower rails and sills bear the impact of Riverside’s unforgiving climate.
Where the rot is limited to just one section of the rail, we carefully remove the damaged timber and splice in fresh new sections using perfectly matched traditional wood. The repair sits naturally with the surrounding timber and the rest of the original window remains completely intact!
We are firmly of the opinion that a window which stays fundamentally intact should not be sacrificed simply because one section of it has developed fault.
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 specific requirements within our workshop and put in them at your property.
Every replacement window is skilfully crafted and custom made in hardwood or treated pine. We carefully ensure to match the profile, proportions, and glazing bar pattern of the original window.
Based in Riverside, we manufacture and install new sash and case windows across the area using high-quality materials and time-honoured techniques.
Our collection of sash and case windows covers everything from a single replacement sash through to a full set of new windows for a listed building.
Double glazing and enhanced security hardware are included as standard features.
Double glazed sash windows in Riverside
Elevate your property and day-to-day living with beautiful double glazed sash and case windows!
Our units are slimline sealed units that sit within the original glazing rebate without changing the sash profile or glazing bar pattern.
From the outside, the timber window appears identical to the original.
Discover why homeowners across Riverside are choosing to improve their classic sash and case windows with double glazing.

Energy efficiency
Our glazing service provides a remarkable improvement to your home’s efficiency.
This means your heating system works far less to maintain a cosy temperature, which straight away results in reduced energy bills for you!
Noise reduction
Sound reduction is an additional advantage that homeowners tend to notice very quickly.
If your home sits on a main road or close to a major junction, double glazed sash windows will minimise noise transmission substantially.
Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is striking, rich in historical significance.
Timber sash and case windows are a defining feature of conservation area heritage, and preserving them matters enormously! Why protect the soul of your building with expert timber window restoration from Woodfellas?
Should your property be located within one of these designated areas, or also have listed building status, the regulations governing window replacement are detailed and carry significant weight prior to undertaking any works.
Our experience working on properties within conservation areas spans more than twenty years.

Sash and case window faults we fix in Riverside
The sash is failing to stay in the raised position and falls back down.
A broken sash cord is the most common repair we carry out on sash and case windows, and as long as the window itself remains in good condition, it is a perfectly straightforward task for our skilled team.
Draughts and rattling
The draught seal between the sash and the frame has either worn away or was never fitted at all. A sash and case window affected by draughts will also tend to rattle noisily in the wind due to that very same gap!
Draught proofing as part of a service helps solve all problems at once.
Rotten bottom rail
The bottom rail of the lower sash is the most vulnerable part of a sash and case window.
Where the rot is restricted to a specific section of the rail, we take out the damaged timber and insert new sections using matching material.
The rest of the original window is left completely undisturbed.
Window stuck shut by paint
Years of coatings applied to the sash to protect it from Scotland’s damp climate can cause it to become stuck to the frame.
We release the sash, wipe down surface areas, fine-tune the fit as needed, and return the mechanism to full working order.
The cords, pulleys and fittings are checked throughout the process, spare you from having to carry out several repair jobs.
Single glazing
Original single-glazed panes surrender their warmth with remarkable ease and offer little protection to the clamour of the street beyond. We swap them out with double glazing whilst retaining every detail of the window’s outward appearance completely intact.
Sash and case windows Riverside FAQs
Is it better to refurbish sash and case windows or replace them?
So what’s the best answer? It really comes down to the condition of the window itself! If the box frame is solid and the sashes are structurally sound, refurbishment is absolutely worth considering. You get excellent performance without sacrificing any of that original character. But if the frame has seriously deteriorated or the timber has rotted beyond saving, replacement is frankly the more sensible and practical option.
Can sash and case windows take double glazing?
Yes. We utilise 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 keeps the appearance of the original.
