Timber sash and case windows can really change any home. But over time, these wonderful windows will need a little extra care and care!
Sash cords break, draught seals deteriorate and bottom rails rot through neglect. The window rattles, jams then fails to close properly.

What is a timber sash and case window
The heading explains the purpose.
The sash refers to the movable glass panel, whilst the case is the hollow timber frame that is constructed within the wall surrounding the window opening.
Nestled 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 moves up as the counterweights drop on the opposite side, and after being released, they hold the sash firmly in place.
Whilst casement windows swing outward on hinges, sash and case windows work by moving vertically.
Each sashes operate independently of one another, allowing you to slip open the window from the top, the bottom, or indeed both simultaneously. This provides your home with superb ventilation control, entirely without a panel swinging inward into the room or outward towards the street.
When the mechanism is working as it ought to, you scarcely notice it is there.
When the cords snap, as they invariably do after years of regular use, the sash falls and stays in that lowered position or gets increasingly difficult to use.
That’s where Woodfellas comes in.

Timber sash window services and refurbishment
Not every classic sash window needs an the same solution.
Our sash windows team in Strathblane spends time to understand the precise requirements of your windows before recommending whether repair or full refurbishment is the most appropriate course of action for you.
Window draught-proofing
A full window refurbishment is an appropriate choice when the existing window remains structurally intact yet is failing to perform as it should.
Our skilled craftsmen use joinery techniques sympathetic to traditional windows, improving your glazing and adding comprehensive draught-proofing throughout your home.
A sensitively restored sash and case window in your Strathblane home should feel as though it could never have been anything other than exactly as it is.
Every installation we undertake is guided by a single ambition: easy operation, silent fitting, and a truly warm presence within the space.
Sash cord and weight replacement
Sash cord replacement is the most frequently completed repair we perform.
When the cords break, the weights remain idle within the case with no connection to the sash whatsoever.
We access the pocket piece, recover the weights, fit fresh sash cords, and align the pulleys with precision.
Our team will consistently check the general condition of the window during the appointment, ensuring that nothing is ever overlooked.
Timber repairs
The bottom rails and sills bear the full force of Strathblane’s severe weather conditions.
Where the rot is localised to a particular section of the rail, we remove carefully the affected timber and fit new sections using carefully matched traditional wood. The repair integrates seamlessly with the surrounding timber, while the remainder of the original window remains completely intact.
We are firmly of the opinion that a window which remains structurally sound should never be sacrificed simply because an single issue affects only one section of it.

Sash and case windows in Scotland’s conservation areas and listed buildings

Timber sash and case windows are a defining feature of conservation area heritage, and maintaining them is hugely important! Why protect the soul of your building with specialist timber window restoration from Woodfellas?

We have completed work on conservation area properties for over twenty years.
We know precisely what the council needs, how to navigate the consent process with confidence, and how to restore or replace windows in a manner that satisfies every requirement without unnecessary delays or repeated correspondence.

Sash and case window faults we fix in Strathblane
Sash failing to hold its position when lifted
Replacing faulty sash cords is the repair our professional team performs most often on sash and case windows, and provided the window is otherwise in good condition, it is a entirely simple task for our skilled professionals.
Draughts and rattling
The seal between the sash and the frame has either deteriorated beyond use or was simply never installed in the first place. That same unforgiving gap responsible for the draughts is just as to blame when the window begins to shake fretfully against the wind.
Draught proofing as part of a package sorts solve all problems at once.
Rotten bottom rail
The bottom section of the lower sash is the most vulnerable component of a sash and case window.
When the rot is limited to a particular section of the rail, we cut away the damaged timber and splice in fresh new sections using closely matched material!
The rest of the original window remains entirely undisturbed.
Window stuck shut by paint
Decades of paint layered upon the sash in an effort to shield it from Scotland’s constantly wet weather can cause it to become tightly sealed against the frame.
We remove the sash from its housing, thoroughly clean all surfaces, make any required adjustments to ensure a proper fit, and restore the mechanism to proper working order.
The cords and pulleys are carefully inspected throughout the process, saving you from dealing with numerous repair jobs down the line.
Single glazing
Original single-glazed panes are particularly inefficient at retaining warmth and offer very little resistance to the intrusion of external street noise. Our upgrade to double glazing preserves the visible profile of your existing window frames completely.
Sash and case windows Strathblane FAQs
Is it better to refurbish sash and case windows or replace them?
Whether refurbishment or replacement is the best 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 thoroughly sensible choice, providing a window that performs beautifully whilst preserving every last trace of its original character. However, if the frame has deteriorated severely or the timber has rotted beyond any hope of repair, replacement becomes the much more sensible and logical course of action.
Can sash and case windows take double glazing?
From the outside, the window appears entirely unchanged, as our slim profile sealed units are designed to sit securely within the existing glazing rebate without any need to broaden the sash or change the glazing bar pattern.
