Bespoke Timber Sash Window Replacement in Bristol

Bristol's Victorian and Edwardian suburbs contain some of the finest period housing stock in the South West — and some of the most neglected sash windows. Clifton, Redland, Cotham, Bishopston, Kingsdown and Bedminster are full of properties built with traditional timber box sash windows that were designed to be integral to the architecture. Many of them now have stuck sashes, broken cords, draughts, or worse — uPVC replacements that look entirely wrong.

Artisawn manufactures and installs new bespoke timber sash windows for Bristol period properties from our workshop in Pylle, Somerset — around 40 minutes from central Bristol. We work across Bristol's Victorian and Edwardian neighbourhoods, producing windows made to the correct proportions and profiles for each individual property, accepted by Bristol City Council conservation officers and suited to the buildings they go into.

Why Bristol Sash Window Work Needs a Specialist

Bristol is not short of window companies. What it is short of is specialist sash window joiners who understand how a traditional box frame is built, what the correct proportions are for a Victorian Bristol terrace, and how to navigate Bristol City Council's conservation framework without creating problems for the homeowner.

The majority of Bristol's period housing stock was built between 1860 and 1910 — a concentrated period of Victorian and Edwardian construction that produced the dense, architecturally consistent terraces and semis that define Clifton, Redland, Cotham and the surrounding neighbourhoods. These properties were built with timber sash windows that were designed to specific proportions for each street and building type. Fitting a window that is even slightly wrong in frame depth, glazing bar width or rail proportion is immediately visible — and in Bristol's conservation areas, potentially a planning problem.

We work in Bristol regularly and understand both the architecture and the planning environment. We know which streets are within conservation areas, what Bristol City Council's conservation officers are likely to accept, and how to make windows that look right for the specific building they are going into.

Bristol's Period Properties — Getting the Window Right

Bristol's Victorian and Edwardian suburbs each have their own character, and the sash windows that belong to them reflect that. Getting a new window right in Bristol means understanding which period and style your property represents.

Clifton — Georgian and early Victorian

Clifton is Bristol's most architecturally significant suburb — a mix of Georgian terraces, Regency villas and early Victorian townhouses built from the 1780s through to the 1850s. Georgian sash windows in Clifton are characterised by very slender glazing bars, six-over-six pane arrangements and fine ovolo or lamb's tongue profiles. The Clifton conservation area is one of the most carefully managed in Bristol — windows that are even slightly wrong in proportion or profile will be noticed by conservation officers and neighbours alike. We reproduce Clifton-period profiles accurately from surviving originals.

Redland and Cotham — mid to late Victorian

Redland and Cotham were developed predominantly between 1860 and 1895 — large Victorian terraces and semis built for Bristol's professional classes. Sash windows from this period are typically four-over-four with lamb's tongue or ovolo glazing bars, more substantial bottom rails than earlier periods, and deeper box frames. These are among the most common windows we work on in Bristol and the period we know best. The Redland and Cotham conservation area has strong controls — timber is the only acceptable material.

Bishopston, Ashley Down and Horfield — Edwardian

The streets north of Redland — Bishopston, Ashley Down, parts of Horfield — were built predominantly in the Edwardian period between 1900 and 1914. Edwardian sash windows are typically two-over-two or four-over-four with wider glazing bars than Victorian, sometimes incorporating margin lights or coloured glass in the upper sash. The architecture is slightly more varied than the strict Victorian terraces of Redland, and the windows reflect that. We work on all Edwardian Bristol property types and can advise on the correct window for your specific building.

Bedminster and Southville — Victorian workers' terraces

South of the river, Bedminster and Southville contain dense Victorian terrace stock built between 1870 and 1900 for Bristol's working population. These properties have smaller sash windows than the grander Clifton and Redland houses — typically two-over-two or four-over-four on a tighter budget with simpler profiles — but they are architecturally consistent and increasingly valued by buyers who want period character. Parts of Bedminster and Southville are within conservation areas and the same care over proportions applies.

Kingsdown — Georgian and Regency

Kingsdown, above the city centre, contains some of Bristol's finest Georgian and early Regency townhouses — a less well-known but architecturally significant area with a mix of listed buildings and conservation area designation. Georgian sash windows here are similar in character to Clifton — fine glazing bars, generous proportions, accurate profiles essential.

Sneyd Park, Stoke Bishop and Westbury-on-Trym

The larger Victorian and Edwardian detached and semi-detached properties on Bristol's western edge — Sneyd Park, Stoke Bishop, parts of Westbury-on-Trym — often have larger sash windows than the terraces, sometimes with bay arrangements incorporating sashes and fixed lights. We work on all of these property types and can survey and quote for projects of any scale.

Planning and Conservation in Bristol — What You Need to Know

Bristol City Council has designated a significant number of conservation areas across the city's period property neighbourhoods. Understanding your planning position before starting window work in Bristol is essential.

Conservation areas

The Clifton, Redland, Cotham, Montpelier, Kingsdown, Bedminster and parts of Bishopston conservation areas all restrict permitted development rights for window replacement. Within these areas, replacing windows — particularly changing materials from timber to uPVC or aluminium — requires prior approval or full planning permission. Bristol City Council's conservation team is active and enforcement does happen.

The good news is that replacing uPVC with correctly proportioned timber — which is exactly what we do — is almost always welcomed by Bristol conservation officers. It is a change that improves the appearance of the building and the conservation area, and it is rarely refused.

Listed buildings in Bristol

Bristol has a significant number of listed properties, particularly in Clifton, Kingsdown and the city centre. Listed building consent is required for any window replacement in a listed property. We can assist with consent applications, providing condition reports, scaled drawings and specification statements in the format required by Bristol City Council. Where repair rather than replacement is appropriate — which we always assess honestly — consent is generally not required.

 

What We Do in Bristol

New box frame sash windows

Where original frames are beyond repair or where previous replacements need removing, we manufacture complete new timber box frame assemblies for Bristol properties. Every window is made to the correct proportions and profiles for the period and character of your building — Georgian six-over-six for Clifton townhouses, Victorian four-over-four for Redland terraces, Edwardian arrangements for Bishopston semis. Full detail on our manufacturing process and glazing options is on our new sash windows page.

Replacement sashes for existing box frames

Where original Bristol box frames remain structurally sound — which is more common than many homeowners expect — manufacturing new double glazed sashes to fit the existing boxes is the most sympathetic and cost-effective approach. We retain the original frames, fit new double glazed sashes balanced against the original lead weights, and apply full draught proofing. The window performs significantly better while looking exactly as it always has.

Removing uPVC from Bristol period properties

We remove uPVC sash windows from Bristol properties and replace them with correctly proportioned timber box frames. This is one of the most common enquiries we receive from Bristol homeowners — particularly in Redland, Cotham and Bishopston where uPVC was widely fitted in the 1990s and now looks increasingly wrong. The transformation to a Victorian terrace when uPVC comes out and properly made timber goes in is immediate and significant.

Repairs, overhauls and draught proofing

Not every Bristol sash window needs replacing. We carry out full overhauls, timber repairs, sash cord replacement and draught proofing across the city. Original Victorian sash windows in Bristol are almost always repairable — even those that appear badly deteriorated. A properly overhauled and draught proofed original window will outperform a cheap replacement on every measure that matters.

Based 50 Minutes From Bristol

Our workshop is in Pylle, near Shepton Mallet in Somerset — approximately 40 minutes from central Bristol via the A37 or A368. We visit Bristol regularly for surveys and installations and can typically arrange a survey within one to two weeks of an enquiry. There is no additional travel charge for Bristol projects within our standard service area.

Being Somerset-based rather than Bristol-based keeps our overheads lower than city competitors — which means competitive pricing without compromising on the quality of the joinery or the care of the installation.

Questions Specific to Bristol

I'm in the Redland or Cotham conservation area — do I need permission to replace my sash windows?

Within Bristol's conservation areas, permitted development rights for window replacement are restricted. If you are replacing like-for-like in matching timber, prior approval from Bristol City Council may be sufficient. If you are changing materials or significantly altering the appearance, full planning permission is likely to be required. We advise on this as part of every survey — and in our experience, correctly proportioned timber replacements are consistently approved in Redland, Cotham and the surrounding conservation areas.

My Clifton property is listed — can you replace the windows?

Yes, with listed building consent from Bristol City Council. We can assist with the consent application, providing the condition reports, scaled drawings and specification statements that Bristol's conservation team requires. 

Can I have double glazing in a Bristol conservation area?

Yes, in most cases. Slimline double glazed units in correctly proportioned timber sash frames are accepted within Bristol's conservation areas provided the overall appearance of the window is not significantly altered. The glazing bar widths, frame depths and sight lines need to be correct — which they will be, because that is how we make every window. We can confirm the position for your specific property and conservation area during the survey.

I have uPVC sash windows in my Victorian terrace in Bishopston — can you replace them with timber?

Yes — and this is exactly the kind of project we do regularly in Bishopston, Redland and Cotham. We remove the existing uPVC frames, make good the reveals, and install new handmade timber box frames made to the correct proportions for your property and period. If your property is within a conservation area and the uPVC was fitted without permission, we can also advise on resolving the planning history as part of the project.

Can you match the glazing bars on my Victorian Bristol terrace?

Yes. Victorian glazing bars in Bristol terraces are typically with a lamb's tongue or ovolo moulding — slightly heavier than Georgian profiles but still relatively slender. We have extensive tooling for Bristol Victorian profiles and work from surviving original windows on the building or terrace wherever possible. The finished window is indistinguishable from the original.

Do you cover South Bristol — Bedminster, Southville, Totterdown?

Yes. We cover all of Bristol south of the river including Bedminster, Southville, Totterdown, Windmill Hill and Knowle. Victorian terrace work in South Bristol is something we do regularly. There is no additional travel charge.

How quickly can you survey a Bristol property?

We typically arrange Bristol surveys within one to two weeks of an enquiry. Call us on 07447 592226 or email info@artisawn.co.uk and we will confirm availability when we speak.
