Aluminium for
every project stage.
Choose the situation closest to your project. We will confirm the right system, measurements and installation scope during the site visit.
Old steel or wooden frames that rust, warp, leak and drive up electricity bills. You want it fixed once — properly. We remove the old frames, fit new aluminium ones and plaster the wall around them.
This is me — let's talkExtending means new openings — and you need them to match the existing style, colour and quality. We custom manufacture every piece to your measurements so the extension looks like it was always there.
This is me — let's talkA patio that leaks, a space that wastes heat, or a room you need to divide without ruining the look of your home. Folding and sliding aluminium systems turn open spaces into fully functional, weatherproof rooms.
This is me — let's talkNew builds need someone who arrives on time, measures correctly, manufactures to spec and installs cleanly so other trades can follow. We work with homeowners and contractors — and we don't leave a mess.

Walls left paint-ready — one team, full jobWhat you gain when you
upgrade to aluminium.
Steel rusts. Wood warps. Old frames leak. The switch to aluminium isn't just aesthetic — it changes how your home feels, performs and costs to run.
Aluminium frames are durable and low-maintenance when they are properly fabricated, glazed, installed and cared for.
Quality weather seals on every frame mean no more water coming in around windows, no cold drafts under the door and no wind noise at night.
Correctly fitted frames and seals help reduce drafts, wind noise and unwanted water entry around openings.
We specify suitable glass for the opening and can include matching burglar bars or stronger glazing where required.
White, Bronze, Charcoal, Natural or Black — powder-coated to last. We match your existing frames if you're extending, or go fresh if you're replacing everything.
No painting, no sealing, no rust treatment. Wipe down with a damp cloth and you're done. Aluminium gives you your weekends back.

Project feedback from homeowners who chose Nactor for replacements, extensions and patio enclosures.
"I had steel windows throughout the house that had been leaking for years. Nactor came out, measured everything, sent me a design with the quote and the whole job was done in a day. The plastering was neat — my painter was happy when he arrived. Cannot fault them."
Steel replacement · Full install"We were extending the house and needed windows and a sliding door that matched what we already had. They matched the colour exactly and the new frames look like they were always there. No mess, no delays. I've already recommended them to my brother."
Home extension · Colour match"We wanted to enclose the patio with folding doors — had quotes from three companies. Nactor was the only one who came out, drew up an actual design and included it in the quote. The doors are beautiful. The whole space is transformed. Worth every cent."
Patio enclosure · Folding doorsWhat does
it cost?
Every opening and specification is different. We measure first, confirm the system and finishing scope, then issue a project-specific quotation.
A small hinged window costs less than a large folding door system. We measure on site and price exactly what your opening requires — nothing padded, nothing guessed.
Any company that gives you a price over the phone without seeing the job is guessing. We measure first so the quote you receive is the price you pay. No surprises on invoice day.
You receive a written quote with the design attached. Exact dimensions, colour, style and layout — all confirmed before any money changes hands or fabrication begins.
We come to you, measure, discuss and design — at no charge and with no obligation. If our quote doesn't work for you, no hard feelings. We'd rather earn the job on merit.
