Wooden sash and case windows are suitable for any household. Over time, these distinctive windows require some extra care.
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 eventually fails to close properly.
Woodfellas has delivered specialist timber sash and case window services to Scottish homes across Erskine for well over two decades, all from our dedicated workshop.
When a window is irreparable, we fix, and also produce bespoke replacement units to order.

What is a timber sash and case window
The title explains you precisely how it functions.
The sash refers to the sliding panel of glass, whilst the case is the hollow box frame that is built within the wall around the window opening.
Inside every case sit two weights, one supporting the upper sash and one supporting the lower. These are suspended from sash cords that pass over pulley wheels positioned at the top of the frame.
Lift the lower sash and the weights drop on the opposite side. Let go of 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 operate independently of one another, allowing you to 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 system is functioning correctly, you hardly think about it at all.
When the cords break, as they often do with years of use, the sash drops and becomes stuck or becomes hard to operate.
That is exactly where Woodfellas can make all the difference.

Timber sash window services and refurbishment
Not every traditional sash window requires an the same solution.
Our sash windows team in Erskine takes the time to truly understand the specific requirements of your windows, so that they can confidently recommend whether a repair or a full refurbishment is the best suited course of action for you.
Window draught-proofing
A full window refurbishment is the best-suited option when the existing window remains sound yet does not manage to function to its full potential.
Our skilled craftsmen employ traditional joinery techniques perfectly suited to period windows, upgrading your glazing and installing comprehensive draught-proofing across your home.
A refurbished sash and case window in your Erskine home ought to feel as though it was always exactly as it should be.
Easy to operate, quiet within its frame, and welcoming in the space it inhabits. That is the standard we work towards with every individual installation.
Sash cord and weight replacement
Sash cord replacement remains the most frequently undertaken repair within the services we offer.
When the cords break, the weights hang unhelpfully inside the case with nothing at all linking them to the sash.
We access the pocket piece, remove the weights, install fresh sash cords, and set the pulleys accurately.
Our team will carefully assess the overall state of the entire window during each visit, ensuring that nothing is ever overlooked.
Timber repairs
Erskine’s lower rails and sills bear the harshest weather elements.
Where rot is confined to part of the rail, we remove the damaged timber and splice in new sections using matched traditional timber. The repair integrates seamlessly with the surrounding wood, leaving the rest of the original window fully intact.
We 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 economical option, we craft brand new sash windows to your exact requirements within our workshop and install them at your property.
Every replacement window is made and made to measure in hardwood or treated pine. We closely match the profile, proportions, and glazing bar pattern of the original.
As timber window manufacturers with pride based in Erskine, we provide and fit brand new sash and case windows across the region, combining quality materials with time honoured heritage techniques!
Our range of sash and case windows encompasses everything from a single replacement sash through to a complete set of new windows for a listed building.
Double glazing and enhanced security hardware are supplied as standard features.
Double glazed sash windows in Erskine
Enhance your home and everyday comfort with double glazed sash and case windows.
Our slim-profile sealed units are made to sit neatly within the original glazing rebate, leaving the sash profile and glazing bar pattern completely unchanged.
From the exterior, the timber window looks the same to the original.
Here is the reason so many property owners throughout Erskine are choosing to upgrade their traditional sash and case windows with double glazing.

Energy efficiency
Our glazing service delivers a significant improvement to your home’s energy efficiency.
This translates directly into lower energy bills, as your heating system no longer needs to work as hard to maintain a pleasant and comfortable temperature across your home.
Noise reduction
Sound attenuation is a further advantage that homeowners notice almost immediately.
Residing on a heavily trafficked road or near a major junction, double glazed sash windows offer a significant reduction in the level of noise that gets through.
Sash and case windows in Scotland’s conservation areas and listed buildings
Scotland’s architecture is just as breathtaking as it is imbued with centuries of remarkable history.
The character of conservation areas is something worth preserving with care, and sash and case windows form a meaningful part of that architectural identity. Protect the integrity of your property through expert 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 specific and well worth understanding before you organise any work!
We have completed work on conservation area properties for over twenty years.
We understand what the council demands, how to manage the approval process, and how to restore or replace windows in a manner that meets those requirements without needless delays or revisions.
For a team that is familiar with listed buildings and conservation area work just as closely as they understand the windows themselves, get in touch today to arrange a complimentary site visit and written quotation.
Sash and case window faults we fix in Erskine
Sash not staying in the raised position
Replacing broken sash cords is certainly the most common sash and case repair our expert team tackles, and when the rest of the window is in good working condition it is a wonderfully easy task for our skilled crew!
Draughts and rattling
The draught seal between the sash and the frame has degraded or was never installed in the initial place. A sash and case window that admits draughts will also often rattle in the wind due to the same gap.
Draught proofing in a service package resolves all issues at once.
Rotten bottom rail
The bottom rail of the lower sash is the most exposed part of a sash and case window!
Where the rot is restricted to a specific section of the rail, we remove the damaged timber and insert new sections using matching material.
The rest of the original window remains completely undisturbed.
Window stuck shut by paint
Years of paint applied to the sash to shield it from Scotland’s damp climate can make it become bonded to the frame.
We release the sash, thoroughly clean every surface, carry out any necessary adjustments to the fit, and restore the mechanism to proper working order!
The cables and sheaves are checked during the process, sparing you from many repair jobs down the line!
Single glazing
Original single-glazed panes surrender their warmth with remarkable ease and provide little resistance to the clamour of the street beyond. We replace them with double glazing whilst retaining every detail of the window’s outward appearance entirely intact.
Sash and case windows Erskine FAQs
Is it better to refurbish sash and case windows or replace them?
Whether to restore or swap out depends on the window’s existing condition. A sound box frame with sound sashes makes refurbishment the sensible choice. You maintain good performance without compromising original character. Where the frame has severely deteriorated or timber rot is irreparable, replacement becomes the more practical solution.
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 widen the sash or alter the glazing bar pattern.
