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.
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.
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.
DuraJoin doesn’t subcontract. Every project is surveyed, installed, and signed off by our in-house team. We don’t leave gaps, cut corners, or overpromise.
All work complies with FENSA standards and UK Building Regulations.
Every DuraJoin frame is fitted with a high-performance thermal break. Combined with double or triple glazing, low-emissivity coatings, warm edge spacers, and argon gas, your new units will reduce heat loss and eliminate draughts… without thick, plastic-like frames.

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!
