We install every major aluminium window and door type. All systems are fabricated to order and sized exactly to your openings.
Door systems include:
All systems come with double or triple glazing, depending on your requirements. We offer options for solar control, acoustic glass, laminated security layers, and low-maintenance self-cleaning finishes.
Every product is compliant with current UK regulations for thermal and structural performance.
We know the property types in Clapham. From Victorian terraces to converted flats and modern side extensions, we match the glazing to the character of the building.
If you’re working with planners or in a conservation area, we provide profiles and finishes that match original sightlines. If you’re designing something new, we build glazing packages around your layout, opening types, and required access.
We do not use generic systems. We do not fit off-the-shelf sizes. Everything is made to suit your project, your structure, and your finish level.
We start with a proper survey. That includes measuring your openings, checking structural conditions, and confirming access. Once the quote is approved, we move straight to fabrication. You’ll know the lead time up front.
Our installation team handles the fitting. We do not hand it off to third-party crews. We show up on time, protect your site, and leave clean.
Most installations are completed in one to three days, depending on size and complexity. We work around other trades when required. We seal, finish, and check every unit before sign-off.
Most window and door replacements in Clapham do not require planning permission. If you’re in a conservation area or listed property, we can advise on the right profiles and assist with drawings if needed.
All of our glazing systems meet current Part L thermal performance standards. We also meet Part F requirements for ventilation where applicable. You will receive product specs and U-value documentation as part of your project file.
Yes. We install across Clapham Common, Clapham North, Clapham South, and surrounding areas. We also work in nearby postcodes across SW4 and SW11.
Yes. Our windows and doors come with a manufacturer’s product warranty. Installation work is also guaranteed and documented at handover.
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!
