Aluminium is stronger than timber or uPVC. It supports larger glazing areas with slimmer frames and delivers a clean, architectural finish. It does not warp, rot, or discolour, and it does not require ongoing maintenance.
We supply systems with thermally broken frames and energy-efficient glazing to reduce heat loss and prevent condensation. Security features come built in, including multi-point locking, internal glazing beads, and reinforced profiles.
You can choose any RAL colour. Dual colour options are available for different interior and exterior finishes. All products are powder coated and certified for long-term durability.
Our aluminium systems are custom built for each client and made to order. We do not offer generic stock items. Every product is designed to suit your property, opening, and layout.

Door Options:
We offer all frames with double or triple glazing. Glass upgrades include solar control, acoustic laminated glazing, and self-cleaning coatings. All products are compliant with UK Building Regulations.
Richmond has a diverse mix of period homes, modern apartments, and riverside properties. Every home requires a tailored approach. We do not supply one-size-fits-all glazing.
For heritage homes and conservation areas, we use slimline heritage profiles and can replicate traditional sightlines. For contemporary homes and rear extensions, we supply clean modern frames with wide glass spans.
All our systems are fabricated to match your layout and design requirements. We align the style and function of the glazing with the look and structure of your property. You get performance and visual consistency.
We handle everything from survey to installation. No outside labour is used. Every step is managed by our own experienced team.
A site survey is completed before finalising specs. We take full measurements, assess access, and confirm all requirements. Once approved, fabrication begins.
Installation typically takes one to three days. Our team handles removal of old units, clean cutting and fitting of the new system, full sealing, and final finishing. We coordinate with builders or roofers if needed and leave the site tidy and complete.
All work is guaranteed.
Most aluminium window and door installations fall under permitted development. If your property is listed or within a Richmond conservation area, we assist with compliance.
We provide technical drawings and specification documents if planning or building control approval is needed. We also supply profiles suitable for heritage settings.
All installations are completed to meet Part L energy standards and Part F ventilation requirements. Certification is issued upon completion.
Yes. We work across all parts of Richmond including Richmond Hill, St Margarets, North Sheen, and the surrounding TW9 and TW10 areas.

EXCELLENT Based on 44 reviews Tom Morgan18/07/2025Trustindex verifies that the original source of the review is Google. The aluminium windows from this lot are bloody brilliant at keeping the noise and cold out. Barely hear a peep from outside, and the heating bills have dropped a fair bit. The team knew their stuff, turned up on time, and did a proper job. If you’re after comfort and saving a few quid, give ’em a bell. Danny Thomson17/07/2025Trustindex verifies that the original source of the review is Google. Sorted me out with a new front door sharpish. Quality’s top-notch, and measured up within days. Wouldn’t hesitate to recommend them. Elijah Barrett17/07/2025Trustindex verifies that the original source of the review is Google. Durajoin fitted aluminium windows last month. Proper made up with ’em - look smart, keep the noise out, and the insulation’s spot on. Cheers, lads! Matthew Burton11/07/2025Trustindex verifies that the original source of the review is Google. Just had a new front door fitted in my flat. Price was well reasonable, fitted to a proper high standard, and the communication was bang on throughout. Popped over to their workshop to chat about what I wanted, and the lads really knew their stuff about handles, locks, glass and all that - even helped me decide between PVC and composite. Cheers!
