Double internal glazed Doors
We supply, install, and replace double-internal glazed doors for homeowners requiring enhanced thermal or acoustic isolation between distinct living spaces, such as separating a home office from a noisy living area.

What Are the Benefits of Installing internal glazed Doors?
Installing internal glazed doors increases natural light, creates a greater sense of space, improves interior aesthetics, maintains room separation, supports energy efficiency through improved daylight distribution and can increase your property’s overall appeal. Modern internal glazed doors are available in a variety of frame finishes and glass styles, allowing homeowners to balance privacy, functionality and design while complementing both traditional and contemporary interiors.
Increases Natural Light
Internal glazed doors allow daylight to pass freely between adjoining rooms, reducing dark areas within the home and creating brighter living spaces throughout the day. Clear glazed doors are particularly effective in hallways, landings and internal rooms with limited access to external windows, helping distribute natural light more evenly across the property.
Creates a Greater Sense of Space
The glazed panels provide uninterrupted sightlines between rooms, making interiors feel larger and more open without removing the practical separation provided by internal doors. This makes internal glazed doors particularly suitable for open-plan living areas, dining rooms, kitchens and home offices where homeowners want defined spaces without creating a closed or confined atmosphere.
Improves Interior Appearance
internal glazed doors introduce a contemporary architectural feature that complements a wide range of interior styles, from traditional oak finishes to modern black-framed designs. Available in clear, frosted, decorative, and reeded glass options, they provide homeowners with the flexibility to match existing décor while creating an elegant focal point within the property.
Maintains Privacy While Allowing Light to Flow
Frosted, obscure and textured glazing options provide increased privacy for bathrooms, utility rooms, bedrooms and home offices while still allowing natural daylight to pass between rooms. This combination helps homeowners maintain comfortable living spaces without relying solely on artificial lighting during daylight hours.
Provides Durable and Low-maintenance Performance
Modern internal glazed doors are manufactured from durable timber or engineered cores, with toughened safety glass that resists everyday wear and impacts. High-quality finishes, robust hinges and premium hardware require only routine cleaning and occasional maintenance, providing dependable long-term performance for busy households.
Increase Property Appeal
Professionally installed internal glazed doors contribute to a brighter, more modern interior that many prospective buyers find attractive. Improved natural light, contemporary styling, and high-quality finishes can strengthen a property's overall presentation, particularly during renovations or home improvement projects, while complementing a wide range of architectural styles.

What Our Happy Customers Say
We have had a front door and side panel installed,Team Tim did a great job and were very professional and knowledgeable. Wouldn’t hesitate to recommend the company and this team to any one !
Simon and Brandon fitted our three windows in our garage > studio conversion and were great through the day. Arrived when they said they would, were very polite, respectful and pleasant people. Found answers to questions we didn’t realise about the installation and though we haven’t yet finished the project the windows are a very exciting and big step forward for us. Would recommend this company and this team without hesitation. Thank you!
Had a problem with our door which was installed 3 years ago - Bowalker - Dean - came to site within 24 hours and helped resolved- thank you ! Very pleased with professional and prompt service
Excellent service from a local independent company. Highly recommend.
I had replacement windows installed. Design and advice was good and cost was competitive. Installation was started in a good time to a good standard.
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
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
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.

Frequently Asked Questions
What Are internal glazed Doors?
internal glazed doors are interior door systems featuring glass pane inserts integrated into a structural frame manufactured from timber, aluminium, composite materials, or steel. They are popular alternatives to solid timber internal doors because they allow natural light to flow between rooms, create a more spacious visual feel, and add architectural character while still providing physical room separation.
How Much Does internal glazed Door Installation Cost?
The installation cost of a internal glazed door ranges from £350 to £1,800+ per door, depending on frame materials, door size, single or double configuration, the type of safety glass chosen, and specialised tracking or hardware systems. Simple single-pane timber-glazed doors sit at the lower end of the range, while complex steel-framed heritage systems or multi-panel bi-fold doors sit at the upper end.
How Long Does internal glazed Door Installation Take?
An individual standard internal glazed door installation takes between 1 and 3 hours to fit, depending on whether it is going into a pre-existing plumbing or structural frame or requires custom frame adjustments. Replacing all internal doors across a standard 3-bedroom home takes our in-house team 1 to 2 days to complete with minimal disruption.
What Guarantee Do You Provide on internal glazed Door Installation?
At Bowalker, we provide a 10-year insurance-backed guarantee for all internal glazed door installations and replacements, protecting installation quality, structural stability, and operational performance. Every project is completed by our fully certified, in-house team to guarantee elite craftsmanship and compliance with domestic structural safety guidelines.
Do I Need to Be at Home During the Installation?
No, you do not need to be home during your internal glazed door installation, provided our in-house installation team has clear, authorised access to the property and all specific hardware styles and opening directions have been confirmed in advance. Our trustworthy, fully vetted installers manage the worksite neatly and secure the property upon departure.
How Much Does It Cost to Replace internal glazed Doors?
The cost to replace internal glazed doors ranges from £500 to £3,500+ per opening, depending on structural modifications, the removal and disposal of old heavy frames, wall alterations for pocket doors, glass choices, and custom architectural styling. Standard single-door swaps are highly cost-effective, whereas large structural French or multi-pane tracking partitions require more complex structural adjustments.
