Expertly Built Aluminium Windows for Southgate Homes
Every home needs better light, stronger security, and improved efficiency. Aluminium windows do all three.
We manufacture and install fully thermally broken, A-rated aluminium window systems tailored for your property type and performance needs.
Choose from casement, tilt-and-turn, fixed, or shaped windows. They are all built from architectural-grade profiles and finished to match your home inside and out.
There are no cold spots, sticking, or swelling; there are just clean lines, quiet operation, and long-term reliability.
Made-to-Measure Aluminium Doors for Southgate Extensions & Upgrades
Aluminium is no longer just for new builds. With slimmer frames, dual-colour finishes, and traditional bar detailing available, DuraJoin can deliver aluminium windows and doors that suit both period properties and contemporary extensions across Southgate.
If you’re replacing timber or uPVC, we’ll match proportions, sightlines, and glass sizes. If you’re building from scratch, we’ll help you maximise natural light and thermal performance without compromise.
Designed for Period & Modern Properties
Our aluminium doors are designed for precision movement and years of use, not just looks.
We install sliding, bifold, French, and front entrance doors, all custom-manufactured to your opening. Available in any RAL colour, with integrated thermal breaks, advanced security locking, and premium handle/hardware options.
Built for modern family life. Backed by structural guarantees.

Frequently Asked Questions
Will aluminium windows and doors reduce noise?
Yes. With laminated or acoustic glazing, aluminium windows can cut outside noise significantly. We recommend this for homes near the A406 or under Heathrow/City Airport flight paths.
How secure are aluminium doors?
Very secure. Every unit comes with multi-point locking, internal glazing beads, and toughened glass. Additional upgrades like PAS24 compliance are available for added peace of mind.
Can you match my current window style?
Yes. We replicate sightlines, bar layouts, and even traditional details for replacements. Whether you’re switching from timber or uPVC, we match proportion and visual balance.
Do I need planning permission?
In most cases, no, especially for like-for-like replacements. We’ll confirm this during the survey. Conservation areas may require approval, but we provide all necessary specs and drawings if needed.
What’s the typical lead time?
6–8 weeks from survey to install. This includes manufacturing, delivery, and scheduling. Express options may be available for standard colours or frame types.
Do you cover structural work too?
 Yes. If lintel replacement or widening is required for new doors or larger openings, we coordinate this as part of the installation.
