Who Is This For

Sound
familiar?

You don't need to fit a specific mould. If any of these match your situation — we're the right call.

01
Replacing Old Frames
Your steel windows are rusting, leaking and letting in the cold.

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 talk
02
Home Extension
You're adding a room and need windows and doors that match your home.

Extending 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 talk
03
Patio Enclosure & Room Division
You want to enclose your patio or divide a space — properly.

A 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 talk
04
New Build
You're building new and need a reliable aluminium supplier and installer.

New 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.

This is me — let's talk
What We Make & Install

Everything in aluminium.
Made for your home.

Custom manufactured to your exact measurements. Every type of door and window — installed properly, finished neatly, built to last. Aluminium costs more than steel upfront and far less over the next 20 years. We price fairly because we're local and we stand behind every installation.

Why Nactor

We're not a franchise.
Not a call centre.
We're local.

Big companies dispatch whoever is available. We show up ourselves — we measure, we design with you, we fabricate it and we install it. One team, one standard, every time.

01
We come to you — at no charge.

Site inspection, measurements, design discussion — all done at your home, at no cost to you. We don't charge a call-out fee because we want to earn the job on merit, not lock you in upfront.

No call-out fee. Ever.
02
You see the design before you decide.

We send your quote with the actual design attached. You know exactly what you're getting — the dimensions, the style, the colour — before you say yes. No vague descriptions, no surprises on install day.

Quote includes the design.
03
One company. Full job. Start to finish.

We remove old frames, supply and fabricate the new ones, install them correctly and plaster the walls around them — paint-ready. You don't coordinate anyone else. One call, one team, one invoice.

Supply · Fit · Plaster · Done.
04
Custom to your home. Made locally.

Nothing is off the shelf. Every window and door is manufactured to your exact measurements at our Randburg workshop. Local production means faster turnaround and direct accountability — we made it, we stand by it.

Fabricated in Randburg.

We're aware that price matters. Aluminium done right costs more than a rushed steel replacement — and it outlasts it by decades. We use quality profiles and hardware because our name goes on every installation. We price fairly because we're local and our overheads are honest.

What Changes

What 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.

No rust. No rot. No warping.

Aluminium does not rust, rot or warp — ever. A properly installed aluminium frame looks and performs the same in 20 years as it does on day one.

Weatherproof — no leaks, no drafts.

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.

Lower electricity bills.

Sealed frames keep heat in during winter and reduce the load on cooling in summer. Better insulation means your geyser and AC work less to maintain comfort.

Security glass and burglar bars.

Safety glass as standard. Optional burglar bars fitted to match the frame. Security without compromising the look — your home stays safe and still looks good.

Custom colours and finishes.

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.

Zero maintenance for years.

No painting, no sealing, no rust treatment. Wipe down with a damp cloth and you're done. Aluminium gives you your weekends back.

"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."

"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."

"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."

Pricing

What does
it cost?

We don't quote blind and we don't give ballpark figures over the phone. Every job is different — but here's exactly what shapes your price and how we keep it honest.

Every job is custom — size, glass and finish drive the price.

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.

We quote after the site inspection — never before.

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.

The quote includes the design — you see what you're paying for.

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.

The site inspection is completely free. No strings.

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.

The only way to know your price
is to let us come and measure.

Free site inspection — no call-out fee, no obligation. We come to you, measure every opening and send a full written quote with the design within 24 hours. Book My Free Site Inspection
