 Trustindex verifies that the original source of the review is Google. Appointment made for a faulty locking mechanism to be fixed on a double glazed window. This was fixed within 30 minutes of the engineer arriving. Service was quick and efficient.
The only downside to the whole process was that we were given a time of mid-morning and the engineer arrived at 8:55 so a little embarrassing as we were not up thinking of a time of around 10.
Having said that the service was excellent.

 Trustindex verifies that the original source of the review is Google. We were recommended KJM Windows by someone in our neighbourhood who had recently had their windows replaced, and we’re so glad we took their recommendation!

From our very first contact with Charles in Sales, he was fantastic at guiding us through the different options and quotes, making the whole process clear and straightforward.

Andy and Kerry, who carried out the survey and technical work, were incredibly knowledgeable, thorough and accommodating, taking the time to make sure everything was carefully considered and explained.

Emma, the Installation Coordinator, was brilliant from start to finish. She kept us regularly updated, was always quick to respond to any questions, and her excellent communication meant we never had to chase for an update.

A huge thank you to Zack, Lester and Shae, who did a fantastic job with the installation. They were friendly, polite and professional throughout, always punctual and incredibly tidy. They were a real pleasure to have at the property, and we couldn’t have asked for a better team. They also deserve a special mention for their excellent choice of radio station!

Simon was also fantastic in making sure that any issues were dealt with promptly and efficiently, and that everything was finished to an exceptionally high standard. His attention to detail and commitment to ensuring we were completely happy with the finished result were greatly appreciated.

From our very first contact to the completion of the installation, everyone at KJM has been incredibly helpful, informative and professional, without ever making us feel pressured or rushed.

Overall, we couldn’t be happier with the experience, the quality of the workmanship and, most importantly, the fantastic team behind it. Everyone we dealt with genuinely went above and beyond to make the whole process straightforward and stress-free.

We would have no hesitation in recommending KJM Windows to anyone considering new windows. A truly fantastic company with an excellent team from start to finish.

 Trustindex verifies that the original source of the review is Google. We chose KJM to fit our doors and windows based on excellent feedback from our immediate neighbours. We were not disappointed. The whole process from start to finish went very smoothly and the surveyor and sales team were extremely helpful and patient while we fine-tuned the specifications.
Zack, Lester and Shae did an amazing job of installing our 8 windows and 2 doors, which have vastly improved the look of our house. We wouldn't hesitate to recommend KJM.

 Trustindex verifies that the original source of the review is Google. Total house replacement windows, front door and aluminium garden doors fitted this week.  The reason I chose KJM was because the initial approach was friendly, efficient and organised. Thank you Charles for making the choices and ordering a good experience. Charlie and Ryan were fantastic fitters, punctual, polite, friendly and have done a really fantastic job.  Simon appeared on site every day to check on progress and quality and spent time once the windows were in checking the finishes and noting any snagging required.   Been the best experience all along.  THANK YOU.

 Trustindex verifies that the original source of the review is Google. We couldn't be happier with our new windows and doors from KJM Windows & Doors!

Over the summer, we had all of our windows and doors replaced with uPVC windows and beautiful agate grey composite doors. We also had French doors fitted where there was previously a window, which has completely transformed the space and made such a difference to our home.

It was a big job, and we got quotes from several other companies before choosing KJM. Their price was very reasonable, and looking back, we'd choose them again in a heartbeat.

From start to finish, the service was outstanding. Charles was brilliant during the quoting stage—knowledgeable, helpful, and never pushy. The office team kept everything running smoothly and were always friendly and responsive.

A special thank you to Zac and Lester, who carried out the installation. They were incredibly polite, friendly, hardworking, and took real pride in their work. Their attention to detail was second to none, and they left everything clean and tidy each day.

Finally, Simon's quality control visit really showed KJM's commitment to getting everything perfect.

The whole team has been fantastic, and the finished result has exceeded our expectations. The quality of the windows and doors is excellent, and we genuinely couldn't be happier. We would thoroughly recommend KJM Windows & Doors to anyone looking for high-quality products, reasonable prices, and exceptional customer service.

Flush Casement Design: Inside and Out

One of the defining features of Residence 7 is its flush design, with the opening sash sitting flush with the outer frame and a flush appearance on the inside as well. This creates clean, consistent sightlines that closely resemble traditional timber joinery.

The 75mm-deep profile is designed to provide the proportions and detailing associated with traditional flush casement windows while offering the low-maintenance characteristics of a modern window system.

Residence 7 can also be customised to suit different properties and architectural styles, with options including:

Heritage and wood-effect colours
Traditional-style handles and hardware
Double or triple glazing
Timberweld and other joint options
Dual-colour finishes

This combination of flush detailing and customisation makes Residence 7 suitable for both traditional properties and homeowners looking for a more refined alternative to conventional uPVC casement windows.

What makes R7 different

Technical Specifications

Feature	Residence 7 Specification
Profile Depth	75mm
Chambers	Seven-chamber profile
Acoustic Performance	Depends on the glazing and complete window specification; acoustic glazing options are available
Window Energy Rating	Up to A++ with the relevant specification
Overall Window U-Value	Up to 1.2 W/m²K with 28mm double glazing / 0.8 W/m²K with 44mm triple glazing, subject to specification
Glazing Options	28mm double glazing or 44mm triple glazing
Maintenance	Low maintenance; no routine painting required
Design	Flush appearance internally and externally

The final performance of a Residence 7 window depends on the complete window, glazing and hardware specification. Where acoustic performance is a priority, KJM can advise on suitable glazing options for the property.

Timberweld: Traditional Appearance with Modern Construction

Residence 7 can be manufactured using Timberweld technology, which creates clean, welded joints designed to complement the flush appearance of the window.

The process provides consistent, neat joints while retaining the traditional proportions and detailing that are central to the Residence Collection’s design.

Timberweld also allows the window to be manufactured and supplied without relying on the traditional mechanically jointed construction associated with older timber-style windows.

For homeowners replacing existing windows, the welded construction provides a clean finish while the modern frame and glazing options deliver the low-maintenance characteristics expected from a contemporary window system.

If a replacement glass unit is ever required, the glazing can be replaced without replacing the complete window frame, subject to the specification and installation.

Modern Security Features

Residence 7 incorporates modern locking and hardware options designed to provide a secure window solution for the home.

The 75mm profile includes dedicated areas designed to provide secure fixing for window hardware, while multi-point locking systems can be specified as part of the overall window configuration.

The final security performance depends on the exact window design, hardware and locking specification selected.

Where a specific security standard or certification is required, KJM can advise on the available specification for your property.

Residence 7 vs Residence 9: The Complete Comparison Guide

A 75mm Seven-Chamber Profile Designed for Modern Glazing

Residence 7 features a 75mm-deep, seven-chamber profile designed to combine the proportions of a traditional flush casement window with the performance characteristics of a modern uPVC system.

The profile is designed to accommodate both 28mm double glazing and 44mm triple glazing, allowing the window specification to be tailored to the requirements of the property.

With a suitable 44mm Argon-filled triple-glazed unit, Residence 7 can achieve an overall window U-value of 0.8 W/m²K. A 28mm double-glazed specification can achieve an overall window U-value of 1.2 W/m²K.

These figures refer to the complete window rather than the glass alone. Actual thermal performance depends on the precise frame, glazing and hardware specification.

Triple Glazing with Residence 7

Triple glazing adds a third pane of glass and a second sealed cavity to the window. When combined with the Residence 7 profile, it can provide a high level of thermal insulation and help maintain warmer internal glass surfaces.

Whether triple glazing is the right choice depends on the property, existing windows, heating requirements, glazing specification and budget.

Window size and quantity – larger windows and larger installations require more materials and installation time.
Double or triple glazing – R7 can be specified with 28mm double glazing or 44mm triple glazing, depending on the thermal performance required.
Colours and finishes – heritage, wood-effect and dual-colour finishes can be selected to suit the property.
Hardware – traditional handles and hardware are available in a range of finishes.
Window configuration – different opening styles, glazing patterns and design details can affect the overall specification.
