Types of Cottage Windows We Install and Replace

Flush casement cottage windows feature a sash that sits level within the frame, creating a clean and streamlined exterior whilst maintaining traditional cottage-style pane designs. Ideal for both heritage and modern homes, these windows offer excellent ventilation, thermal efficiency and a neat, understated look.

Bowalker provides flush casement cottage window installation and replacement services with slimline double glazing, multipoint locking and weather-resistant seals, available in a wide range of finishes. They are perfect for cottage-style renovations, rural properties and homeowners seeking a blend of classic charm and modern performance.

Sliding sash cottage windows combine the classic vertical sliding mechanism with traditional cottage-style pane layouts, such as 6-over-1 designs. These windows are ideal for period properties, offering controlled ventilation and timeless appeal.

Bowalker carries out sliding sash cottage window installations and replacements with smooth operation systems, double glazing and secure locking mechanisms for improved energy efficiency and safety. Available in timber, aluminium or uPVC, they are perfect for restoring heritage homes whilst maintaining authentic character.

Pane pattern cottage windows feature multiple panes of glass divided by astragal bars, offering a traditional look with a distinctive, period-accurate design. Ideal for enhancing the aesthetic appeal of your cottage, these windows combine classic style with modern energy efficiency.

Bowalker delivers pane pattern cottage window installation and replacement solutions with custom grid configurations, high-performance glazing and durable frame materials. Available in various finishes, they are ideal for adding character to both traditional and contemporary homes.

Bay and Bow cottage windows combine multiple panels to create elegant, curved or angular features that enhance natural light and views. These windows not only increase the sense of space but also improve the overall aesthetic of the property.

Bay and Bow windows are especially suited for living rooms or dining areas where natural light is essential. Bowalker handles precise replacement and installation of bay and bow cottage windows in living rooms, dining areas and traditional façades using high-performance double or triple glazing, durable thermally broken frames and weather-resistant seals.

Leaded or grille cottage windows incorporate decorative leaded glass, Georgian bars or applied grilles to enhance the classic cottage appearance, adding texture and period detail whilst maintaining natural light flow. For conservation areas and listed properties, slim-profile double glazing preserves authentic sightlines.

Bowalker installs and replaces these windows in timber, aluminium or uPVC frames, combining Low-E glass and argon-filled sealed units with multipoint locking and weather seals, delivering A-rated efficiency, enhanced security and low-maintenance construction for period and modern properties alike.

Arched and cathedral cottage windows feature curved or taller pointed tops, adding vertical emphasis and architectural interest inspired by classical or Gothic elements. They can be fixed, casement or sash styles and suit gable ends or prominent cottage elevations.

Bowalker Windows carries out expert replacement and installation of arched and cathedral cottage windows using durable materials such as timber, thermally broken aluminium or mechanically jointed uPVC for seamless curves. Fitted with high-performance double or triple glazing, they ensure energy efficiency, security and low maintenance whilst preserving historical character and meeting modern comfort standards in traditional homes.

Oriel cottage windows project from the upper floor, supported by corbels or brackets, creating a distinctive cantilevered boxed appearance without extending to ground level. Common in Tudor, Victorian or traditional architecture, they increase natural light, enhance views and add unique character.

At Bowalker, we install and replace oriel cottage windows using durable framing systems in uPVC, aluminium or timber with high-performance glazing options, ensuring energy efficiency, security and low maintenance. They are ideal for first-floor elevations in countryside cottages, preserving historical integrity whilst boosting architectural appeal and interior comfort.

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 Cottage Windows?

Cottage windows are traditional-style windows often found in period properties, designed to preserve the historic charm whilst offering modern energy efficiency and functionality. These windows include styles such as flush casement, sliding sash and pane patterns, often featuring multiple panes divided by astragal bars to reflect a classic aesthetic.

How Much Does Cottage Window Installation Cost?

Cottage window installation costs between £500 and £1,800 per window, fully fitted. The final price depends on the material (uPVC, aluminium or timber), window size, style and glazing, as well as period-accurate features such as Georgian bars, astragal bars or leaded designs. Timber, sliding sash and bay and bow styles sit towards the upper end, while standard uPVC casements are the most economical. Property access and installation complexity also affect the overall cost.

What Materials Are Cottage Windows Made From?

Cottage windows are made from timber, uPVC or aluminium, with each material offering its own set of benefits. Timber provides an authentic, traditional look, whilst uPVC and aluminium offer durability, low maintenance and energy efficiency, often with the added benefit of double glazing.

How Long Does Cottage Window Installation Take?

Cottage window installation takes 1-2 hours per window, with a full installation for a standard 3-bedroom house usually completed in 2-3 days. The time required can vary based on window type, removal of existing frames and property access.

What Guarantee Do You Provide on Cottage Window Installation?

Bowalker Windows Limited offers a 10-year insurance-backed guarantee on all cottage window installations, ensuring long-lasting reliability and peace of mind. This guarantee covers workmanship and installation quality, providing protection for your investment.

Do I Need to Be at Home During the Installation?

No, you do not need to be at home during the cottage window installation as long as we have access to your property and your preferences are confirmed beforehand. Our in-house team will handle everything professionally and ensure the job is completed to your satisfaction.

How Much Does It Cost to Replace Cottage Windows?

Replacing cottage windows usually costs between £500 and £1,900 per window or more. This includes removing and disposing of the old windows and fitting new units with modern double glazing. Prices vary with material, size, style and decorative features such as glazing bars or leaded glass, and any structural or making-good work required will add to the figure. For an accurate price, Bowalker provide a free survey and a fixed, no-obligation quote.

What Are the Maintenance Tips for Cottage Windows?

To maintain cottage windows, clean the frames and glazing a few times a year with warm soapy water and keep the weather seals and drainage holes clear to prevent draughts and damp. Lubricate the hinges, locks and any sliding sash balances periodically so they continue to operate smoothly. Timber frames need occasional repainting or re-sealing every few years to guard against moisture and rot, while uPVC and aluminium require only routine cleaning. If condensation appears between the panes of a double-glazed unit, the seal has failed and the unit should be replaced.
