Types of Historic Windows We Install and Replace

Double-hung sash windows feature two independently sliding sashes that move vertically within the frame, allowing precise control over ventilation at both the top and bottom. Available in timber, uPVC and aluminium, with modern double glazing and weather seals, they are best suited to Victorian and Georgian-period homes, delivering classic aesthetics, excellent airflow and strong thermal performance.

Bowalker specialises in the precise installation and replacement of these windows, ensuring authentic historic character alongside current standards for energy efficiency and security.

Casement historic windows are side-hinged frames that open outward like a door, available in both side-hung and top-hung configurations to suit different property types. They provide maximum ventilation, unobstructed views and slim sightlines, and can be fitted with double glazing and multipoint locking for security and thermal performance.

Ideal for traditional homes and properties in conservation areas where authentic detailing and good airflow are priorities, Bowalker offers expert in-house installation that preserves your property's heritage whilst improving energy efficiency and overall performance.

Palladian and arched historic windows feature elegant curved or rounded tops inspired by classical architecture, with each window made to measure to match your property's existing openings precisely, a critical consideration for listed buildings and conservation area properties. Fitted with energy-efficient glazing, they deliver architectural grandeur, enhanced natural light and strong thermal performance.

Best suited to period properties seeking to add stature to principal elevations, Bowalker specialises in the careful installation of these windows, maintaining historic authenticity whilst improving insulation, security and comfort.

Bay and bow historic windows consist of multiple angled or curved panels that project outward from the wall, creating a greater sense of space indoors whilst maximising natural light and offering expansive views. High-performance glazing and durable frames ensure excellent thermal efficiency and security.

Where required, we advise on structural considerations such as lintels and supporting bases as part of our full-service approach. Perfect for living rooms and dining areas in period homes wanting both character and comfort, Bowalker provides specialist replacement and installation, preserving your property's historic elegance.

Fixed and picture historic windows are large, non-opening designs focused entirely on light and outlook, providing unobstructed views with premium energy-efficient glazing for superior insulation. Popular choices for stairwells, hallways and above doorways in period properties, they introduce generous natural light into spaces where opening mechanisms are unnecessary or impractical.

Best used as focal points in living or dining areas to frame a landscape or garden vista, Bowalker delivers precise replacement and installation that enhances thermal performance whilst keeping your home's original charm fully intact.

Leaded and stained glass historic windows incorporate intricate patterns set in lead cames, casting vibrant coloured light that adds decorative elegance and historical beauty to any interior. For listed buildings and conservation area properties, we ensure all replacement work meets local authority requirements, using like-for-like lead profiles and glass types to satisfy planning and heritage obligations.

Fitted with secure, energy-efficient glazing, they are ideal for period homes and heritage buildings seeking unique artistic character. Bowalker offers expert replacement and installation, retaining original decorative appeal whilst improving insulation and security.

Clerestory and transom historic windows are positioned high on walls to allow natural light to flood into a room without compromising privacy or sightlines. All replacement installations are carried out in compliance with Part L of the Building Regulations, ensuring your high-level glazing meets current thermal performance requirements.

Perfect for period properties, they add a distinctive architectural quality whilst improving ventilation and light distribution throughout the home. Bowalker specialises in the installation of these windows using high-quality materials and energy-efficient glazing to preserve heritage character and boost comfort.

Metal historic windows feature slender, steel-section frames with the industrial period elegance characteristic of early twentieth-century architecture. Weather-resistant seals and high-performance glazing deliver lasting security and efficiency, whilst the clean sightlines and bold geometry remain true to the original period aesthetic.

Suited to heritage properties and conservation area homes where the existing fenestration calls for a metal frame, Bowalker delivers accurate replacement and installation that respects your building's historic character whilst providing long-lasting thermal performance and structural strength.

Mullioned historic windows feature vertical bars, known as mullions, that divide a wide opening into two or more separate lights, creating a traditional yet striking appearance characteristic of Tudor, Jacobean and Arts and Crafts period homes. They add strong architectural detail and visual rhythm to a facade whilst remaining practical and well-proportioned.

Bowalker provides precise replacement and installation of mullioned windows, using high-quality materials and energy-efficient glazing to improve insulation and security whilst preserving the authentic character and period integrity of your home.

Bowalker replaced all of our windows and patio doors in November. They are very efficient and got the job done in the pouring rain but did it quick and professionally. We had a couple of teething issues with the doors after completion and they did not hesitate to come out and rectify the issue. Excellent customer service and a friendly team. Would highly recommend

Nic Downer Edited 3 months ago

We had a total of 6 windows fitted at end of June 2025 (2 bathroom(frosted), 1 hallway,1 dining room and two big bay windows complete with 2 window boards). Took 5 days in total as bay windows were load bearing ,the window boards were not in warehouse so took extra time to arrive and fit , the silicone/mastic finish wasn’t great and they cut one end of a window board wrong , but after a telephone call a new team of fitters came out and rectified the mistakes of original fitters that we had noticed , a window pane had got scratched in delivery so they replaced that as well. This was a big job that entailed some mistakes but over time was rectified by bowalker windows by sending out another team of fitters to fix some minor mistakes of original fitters . We went on a recommendation from a work colleague who had used Bowalker windows in the past as were very good. Maybe just improve your fitters mastic silicone skills a bit more but is is an old house of 110 years and nothing is level in this house

As a property developer operating across Brighton and Hove, I rely on trusted trades who consistently deliver — and Bowalker Windows Ltd, led by Zack Newman, is one of those partners. We specify their windows across all our developments because their products meet the high standards our clients expect, installations are completed on schedule, and site coordination with our contractors is seamless. Zack is responsive, pragmatic, and straightforward about lead times and costs, which makes planning and handovers far easier. Their workmanship is excellent, energy-performance claims are reliable, and they stand behind their warranty. Competitive pricing, professional teams, and reliable aftercare mean we’ll continue to use Bowalker Windows on future projects. Highly recommended for any developer or home owners in the Brighton & Hove area.

5 stars! I recently had all the windows in my home replaced by Bowalker Windows and couldn’t be happier with the result. From my very first contact I worked with Zack Newman — he was professional, knowledgeable, and transparent about pricing and timelines. The installation team arrived on time, worked efficiently, and left the house clean. The new windows look fantastic, operate smoothly, and have already made a noticeable difference in comfort and noise reduction. Excellent customer service from start to finish — I highly recommend Zack and Bowalker Windows to anyone looking for quality work and a hassle-free experience.

I am 9 years into our windows installation from Bowalker Windows. I emailed them on Sunday with an issue and by 3pm Monday afternoon they were at my home sorting the issue. This company's attitude to exceeding customer service and going the extra mile is in their DNA. These guys are just amazing from cradle to grave when it comes to windows and doors. I wouldn't go anywhere else. Simply fantastic.

Frequently Asked Questions

What Are Historic Windows?

Historic windows are traditional-style windows designed to replicate the appearance and detailing of period properties whilst incorporating modern materials and performance features such as double glazing, thermally broken frames and multi-point locking. Common styles include double-hung sash, Palladian arch, leaded casement and cottage double-hung windows, each preserving authentic sightlines and glazing bar profiles. They are most commonly specified for listed buildings, conservation areas and Victorian, Georgian and Edwardian properties where period-accurate glazing is a planning requirement.

How Much Does Historic Window Installation Cost?

The cost of installing historic windows in the UK ranges from £800 to £2,800 or more per window, depending on frame material, glazing specification and window type. uPVC historic-style windows generally start from around £800 fitted, timber double-glazed options from £1,200, and aluminium or heritage aluminium profiles from £1,200 to £2,800 or more. Properties in London and the South East carry a 20-30% premium over these figures. Factors such as upper-floor access, structural lintel work and conservation area requirements will also influence the final price. Bowalker provides a no-obligation quote tailored to your property before any work is agreed.

What Materials Are Historic Windows Made From?

Historic windows are made from uPVC, timber or aluminium, each offering distinct benefits. Timber, including engineered options such as Accoya, provides the most authentic appearance and is frequently specified for listed buildings and conservation areas. uPVC offers strong thermal performance, rot resistance and low maintenance, with timber-effect foiled finishes suited to period properties. Aluminium provides slim sightlines, exceptional strength and a corrosion-resistant powder-coated finish with thermally broken profiles achieving low U-values. All three are compatible with double glazing and advanced weather-sealing systems.

How Long Does Historic Window Installation Take?

Historic window installation takes 1 to 2 hours per window. A standard 3-bedroom house takes about 2 days for complete installation, though this may vary based on the scope of work, size of windows and any required structural repairs.

What Guarantee Do You Provide on Historic Window Installation?

Bowalker provides a 10-year insurance-backed guarantee on all historic window installations, ensuring peace of mind and long-lasting performance. This covers both workmanship and installation quality, ensuring compliance with FENSA regulations.

Do I Need to Be at Home During the Installation?

No, you do not need to be at home during installation, provided we have agreed access to the property and your requirements have been confirmed beforehand. Our fully in-house installers carry out every installation to a consistent standard, with no subcontractors involved, so you can have complete confidence in who is on site. We will confirm all details, including window specifications, finish choices and access arrangements before the installation date, ensuring the work proceeds smoothly and exactly to your brief.

How Much Does It Cost to Replace Historic Windows?

Historic window replacement in the UK costs between £800 and £3,000 or more per window, depending on material, design complexity and conservation requirements. Standard uPVC replacements start from around £800 supplied and fitted, timber sash windows from £1,500 and hardwood options such as oak from £2,500 upwards, with bespoke conservation-grade replacements using slimline or vacuum glazing falling between £2,500 and £3,000. Bowalker’s team will advise during your free consultation on whether full replacement or selective restoration offers the better long-term value.

What Are the Maintenance Tips for Historic Windows?

To maintain historic windows, clean frames and glazing regularly using a mild detergent and soft cloth, check seals and EPDM gaskets annually to prevent draughts and water ingress, lubricate hinges, friction stays and multipoint locking mechanisms with a light oil or specialist window lubricant, and inspect sash cords and balance springs on double-hung windows for signs of wear. Timber frames should be repainted or resealed every three to five years using a microporous coating to protect against moisture and swelling, whilst uPVC and aluminium frames require minimal upkeep beyond regular cleaning.
