Types of Wooden Windows We Install and Replace

At Bowalker, we install and replace Sash Windows tailored for Georgian, Victorian and period properties. Featuring vertically sliding sashes within a precision-crafted timber frame, these windows provide traditional character, effective ventilation and balanced natural light.

Our in-house window installers ensure accurate fitting with energy-efficient double glazing, smooth sliding mechanisms, draught-proof seals and secure locking systems. Each sash window installation improves thermal efficiency and preserves heritage aesthetics, delivering the authentic period character and smooth operation that Georgian and Victorian properties deserve.

Flush Casement Windows feature a sash that sits perfectly level with the outer frame when closed, creating a clean, flat appearance inspired by traditional timber and steel windows found in period and Arts and Crafts properties.

At Bowalker, we install and replace flush casement windows tailored to complement your property’s architectural style. Our dedicated in-house fitting team ensures precise installation and replacement with energy-efficient glazing, secure locking systems and weather-resistant timber frames, helping your property retain its architectural integrity whilst benefiting from modern thermal and security standards.

We install and replace Tilt and Turn Windows, a versatile dual-function window style that tilts inward from the top for secure ventilation or opens fully inward like a casement for maximum airflow and easy interior cleaning.

Ideal for modern and contemporary properties, these windows combine practicality with streamlined aesthetics. Our skilled window installers ensure precise fitting using energy-efficient double glazing, secure multi-point locking systems and weather-resistant timber frames, making them a practical and low-maintenance choice for modern homes where ease of cleaning and controlled airflow matter most.

Cottage windows feature a traditional divided design with a smaller upper pane and a larger lower casement opening, separated by a central mid-rail, creating the classic appearance associated with rural and period UK properties.

Common in farmhouses, country cottages and heritage homes, these windows improve natural light, support ventilation and preserve traditional architectural character. We install and replace cottage windows using durable timber frames and energy-efficient double glazing with secure locking systems, preserving the architectural character that makes these properties distinctive, whilst meeting current thermal and security standards.

A Bay and Bow Window projects outward from the main wall, using multiple angled or curved panes to create a wider panoramic view, increase natural light and add architectural character.Our specialist wooden window installers install and replace bay and bow windows tailored for both modern and period properties.

Each installation and replacement uses energy-efficient glazing, secure locking systems and weather-resistant timber frames to improve thermal efficiency, interior space and kerb appeal, transforming both the interior feel and the street-facing appearance of your home in a single installation.

Fixed/Picture Wooden Windows feature large fixed glass panels to maximise natural light whilst creating uninterrupted outdoor views and a clean architectural finish. Suitable for both contemporary and traditional properties, these windows combine minimalist design with reliable thermal performance.

Our professional in-house installers install and replace each window with energy-efficient glazing, durable timber frames and weather-resistant sealing systems, making them a particularly strong choice for stairwells, feature walls and any elevation where light and outlook matter more than ventilation.

Bowalker have been incredibly helpful and provided me with extremely useful information about the windows and doors at a property I moved into, previously supplied by them. Great customer service, really recommend

steph park a month ago

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.
