Wooden sash and case windows adorn many a household. As time passes, however, these distinctive windows will need a little extra care and looking after.
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 has spent over 20 years as timber sash and case window specialists, serving Scottish homes across Glenboig from our workshop.
When a window is beyond repair, we repair, and even craft bespoke replacement units to measure.

What is a timber sash and case window
The title tells you precisely how it works.
The sash refers to the sliding panel of glass itself, whilst the case is the empty box frame that is built 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 rises as the weights drop gracefully on the other side, and when released, they hold the sash perfectly in place.
While casement windows swing outward on hinges, sash and case windows move smoothly in a upward and downward direction.
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 as it ought to, you hardly think about it at all.
When the cords eventually break, as they commonly do after years of regular use, the sash will either simply drop and remain in that lowered position or become progressively difficult to operate.
That’s precisely where Woodfellas step up!

Timber sash window services and refurbishment
Not every traditional sash window needs an exact solution.
Our sash windows Glenboig team closely hears to grasp your window’s requirements before advising whether repair or full refurbishment is the most suitable path forward for you.
Window draught-proofing
A complete window refurbishment is the right choice when the existing window remains structurally intact yet is failing to perform as it should.
Our experienced craftsmen use joinery techniques sympathetic to traditional windows, upgrading your glazing and adding comprehensive draught-proofing throughout your home.
A sympathetically restored sash and case window in your Glenboig home is likely to seem as though it was always entirely and easily meant to be there.
Effortless to open, quiet in the frame and warm throughout the room. That is what we are striving for every time!
Sash cord and weight replacement
Sash cord replacement is the often most performed repair we carry out.
When the cords break, the weights remain sitting uselessly inside the casing with nothing to connect them to the sash.
We take off the pocket cover, remove the weights, fit new sash cords, and align the pulleys correctly.
Our team will thoroughly evaluate the overall condition of the entire window during each visit, making sure that nothing is ever overlooked.
Timber repairs
Bottom rails and sills bear the full brunt of Glenboig’s severe weather conditions.
Where the rot is limited to a portion of the rail, we take out the affected timber and insert new sections using matching traditional wood. The repair blends perfectly with the surrounding timber and the remainder of the original window remains completely intact.
We are strongly of the opinion that there is no need to sacrifice a window that remains in good structural condition simply because an localised issue affects only one section of it.

Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is as breathtaking as it is historically significant.
The character of conservation areas is something worth protecting with care, and sash and case windows form a meaningful part of that architectural identity. Safeguard the integrity of your property through professional timber window restoration carried out by Woodfellas.
If your property is in one of these zones, or is a listed building, the regulations surrounding window replacement are precise and well worth understanding before you organise any work!
Our expertise working on properties within conservation areas covers more than twenty years.

Sash and case window faults we fix in Glenboig
The sash is failing to stay in the raised position and drops back down.
Changing faulty sash cords is the repair our professional team performs most frequently on sash and case windows, and provided the window is otherwise in good condition, it is a quite simple task for our experienced professionals.
Draughts and rattling
The seal between the sash and the frame has deteriorated or was not installed at all in the first instance. A sash and case window affected by draughts will equally tend to rattle when exposed to gusts, owing to the same gap.
With draught-proofing included as part of a service package can help address all concerns in one go.
Rotten bottom rail
The bottom rail of the lower sash is the most highly vulnerable part of a sash and case window.
Where the decay is confined to a particular section of the rail, we carefully remove the compromised timber and splice fresh, perfectly matched material seamlessly into its place.
The remainder of the original window is left entirely undisturbed.
Window stuck shut by paint
Years and years of paint layered onto the sash to protect it from Scotland’s persistent wet weather can end up sealing it firmly to the frame!
We release the sash from its binding, thoroughly clean every surface, adjust the fit wherever, and restore the mechanism to smooth and proper working order once more.
The cords with pulleys are carefully inspected during the process, sparing you from many repair visits down the line.
Single glazing
Original single-glazed panes lose heat quickly and admit street noise. We fit double glazing whilst keeping the visible window profile unchanged.
Sash and case windows Glenboig FAQs
Is it better to refurbish sash and case windows or replace them?
Whether to refurbish or replace depends on the window’s existing condition. A solid box frame with structurally intact sashes makes refurbishment the sensible choice. You maintain good performance without losing original character. Where the frame has badly deteriorated or timber rot is irreparable, replacement becomes the more practical solution.
Can sash and case windows take double glazing?
Yes. We use slim profile sealed units that sit within the existing glazing rebate without widening the sash or altering the glazing bar pattern. From the outside, the window looks exactly as the original always did.
