Wooden sash and case windows grace many a property. As time passes, 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 shakes, sticks, and eventually fails to close properly.
Woodfellas are seasoned specialists in timber sash and case windows, working with Scottish homes throughout Bishopbriggs from our workshop for more than two decades.
When restoring and repairs fall short, we craft entirely bespoke replacements, shaping something new from the very essence of what once was.

What is a timber sash and case window
The title explains the purpose.
The sash refers to the sliding panel of glass, whilst the case is the hollow box frame that is built within the wall surrounding the window opening.
Housed within each case are a pair of weights, one for the upper sash and one to the lower, both suspended from sash cords that run over pulley wheels positioned at the top of the frame.
Lift the lower sash and the weights fall on the opposite side. Release it and they keep the sash in place.
Whilst casement windows swing open outward on hinges, sash and case windows operate by moving vertically instead.
Both sashes glide independently of one another, meaning you can open them from the top, the bottom, or indeed 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 functioning properly, you hardly notice it in the least.
When the cords snap, which they often do after years of wear, the sash falls and remains stuck or becomes very difficult to operate.
That is exactly where Woodfellas comes into its own.

Timber sash window services and refurbishment
Not every classic sash window needs an identical solution.
Our sash windows team in Bishopbriggs takes the time to truly appreciate the particular requirements of your windows, ensuring they can recommend with confidence whether a repair or a full refurbishment is the most suitable course of action for you.
Window draught-proofing
Full window refurbishment works best when the original frame is structurally sound but no longer performing well.
Our experienced craftsmen use traditional joinery techniques to enhance your glazing and install draught-proofing throughout.
A carefully restored sash and case window in your Bishopbriggs house should appear as though it has always been exactly as it was meant to be.
Every fit we carry out is guided by a straightforward aim: easy operation, quiet fitting, and a genuinely warm presence within the space.
Sash cord and weight replacement
Sash cord replacement remains our most frequently performed repair.
When the cords snap, the weights remain idle inside the case with nothing connecting them to the sash.
We reach the pocket piece, retrieve the weights, install fresh sash cords, and position the pulleys with precision.
Our team will carefully assess the overall condition of the entire window during each visit, ensuring that nothing is ever overlooked.
Timber repairs
Bottom sections and sills bear the heaviest brunt of Bishopbriggs’s harsh climatic conditions.
Where the rot is localised to a particular section of the rail, we remove carefully the affected timber and fit new sections using closely matched traditional wood. The repair integrates seamlessly with the surrounding timber, while the remainder of the original window remains completely intact.
We hold firmly to the belief that there is absolutely no reason to sacrifice a window that is still structurally sound just because one portion of it has developed an issue.
Supplying and fitting bespoke sash windows
When a window has reached the point where repair is no longer a economical option, we craft 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 replicate the profile, proportions and glazing bar pattern of your original windows!
Based in Bishopbriggs, we manufacture and install new sash and case windows across the area using premium materials and traditional techniques.
Our range of sash and case windows covers everything from a single replacement sash all the way to a complete set of new windows for a listed building.
Double glazing and enhanced security hardware are included as default features.

Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is breathtaking, carrying with it a highly fascinating historical legacy.
Conservation areas are established to maintain that distinctive character, and sash and case windows form a vital part of it. Safeguard the character of your home with expert timber window restoration carried out by Woodfellas.
If your property falls within one of these designated areas, or if it holds listed building status, the regulations surrounding window replacement are specific and must be clearly understood before you set up any work.
We have carried out work on conservation area properties for over twenty years.
We know what the council requires, how to manage the approval process, and how to restore or replace windows in a manner that satisfies those requirements without unnecessary delays or revisions.
For a team that knows listed buildings and conservation area work as well as they understand the windows themselves, contact us today for a free site visit and written quote.
Sash and case window faults we fix in Bishopbriggs
Sash failing to hold its position when lifted
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 perfectly simple task for our skilled professionals.
Draughts and rattling
The air seal between the sash and frame has failed or was never installed. A leaky sash and case window will also shake in the wind due to the same gap.
Draught-proofing as part of a service package resolves all issues at once.
Rotten bottom rail
The bottom section of the lower sash is the most vulnerable component of a sash and case window.
Where rot is limited to part of the rail, we remove the damaged timber and insert new sections using matched material.
The rest of the existing window remains completely undisturbed.
Window stuck shut by paint
Years of using paint to safeguard the sash against Scotland’s damp climate can cause it to become firmly stuck to the frame.
We loosen the sash carefully, prepare the surfaces carefully, make any required adjustments to the fit, and restore the mechanism to proper working order.
The cords with pulleys are thoroughly inspected during the work, sparing you from numerous repair visits further down the line.
Single glazing
Original single-glazed panes are especially 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 Bishopbriggs FAQs
Is it better to refurbish sash and case windows or replace them?
So what’s the right answer? It really depends on 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 honestly the more sensible and practical option.
Can sash and case windows take double glazing?
From the outside, the window appears entirely unchanged, as our slim profile sealed units are made to sit neatly within the existing glazing rebate without any need to broaden the sash or change the glazing bar pattern.
