Cheap aluminium windows Gauteng: Reduce to Clear stock

Reduce to Clear is stock left over from earlier orders: windows and doors that were made but never installed. They are new, in their original condition, and sold at 50% off the normal price of the matching shop product. There is usually only one of each, so when an item is sold it is gone; sold items show a Sold badge for a while so you can see what has moved.

The live list below always shows what is available today:

Recent items have included Charcoal and Black top hung windows from 600 × 900 mm to 1 200 × 910 mm, at prices from R1 015 excluding VAT where the normal price was R2 029.

How buying Reduce to Clear works

• Pick an item from the list above and check its exact size, layout and colour on the product page.
• Check your opening: clearance items come in one size only, so measure first.
• Pay online, and the item is reserved for you.
• Collect from Laser Park: clearance items are collection only, so they are not delivered.
• Final sale for a change of mind, but a genuine defect is still covered under the Consumer Protection Act and our warranty.

Cheap aluminium windows Gauteng: check the size first

A clearance window only saves money if it fits. Measure the opening at the top, middle and bottom, and at both sides, and use the smallest size. The window should be a little smaller than the opening, about 10 mm each way, so the installer can pack and seal it. If the clearance size is close but not right, a new standard-size window is usually the better buy.

Cheap aluminium windows Gauteng: five ways to pay less

• Choose the Casement 28 frame for top hung and side hung windows: it costs about 15% less than the 30.5 mm Standard frame and suits most bedrooms and bathrooms.
• Use standard sizes. Every standard size is priced online; non-standard sizes are made to measure and quoted.
• Collect free from Laser Park instead of paying for delivery.
• Order the whole house at once. Delivery is charged once per order: R650 excluding VAT within 60 km of Laser Park, plus R4.50 per km beyond that, there and back.
• Pick any colour. White, Bronze, Charcoal, Black and Natural Anodised cost the same, so a modern colour costs nothing extra.

Until 1 December 2026, the Black Friday sale also takes 15% off new aluminium windows and doors in the shop. Reduce to Clear items are already at 50% off and are not discounted further.

Where our low prices come from

Coetz™ prices are low because of how we work, not because of thinner frames or cheaper glass. We make windows in our own Laser Park workshop, so there is no middleman between the factory and you. We make standard sizes in volume, which keeps the cost per window down, and we publish every price online, so you can compare without waiting for quotes. Supply-only pricing means you choose your own builder or installer, and you only pay for fitting once.

Cheap aluminium windows Gauteng for rentals and extensions

Landlords building backyard rooms and families adding extensions are often the buyers who need cheap aluminium windows Gauteng suppliers can deliver quickly. Plan the openings around standard sizes before the walls go up, use the Casement 28 frame for bedrooms and bathrooms, and check Reduce to Clear first, because a clearance window in the right size can halve the cost of one opening.

Clearance or second-hand?

Clearance stock is new and has never been installed, so it comes with laminated glass, a clean finish and the protection of the Consumer Protection Act. Second-hand windows taken out of old houses are often bent, scratched or glazed with old float glass, and rarely fit a new opening. Our guide to second-hand aluminium windows explains what to check if you do buy used.

Getting a cheap window fitted properly

Our windows are supply only, so your builder or a local installer fits them; see aluminium window installers. A cheap window that is badly fitted will leak and rattle, so ask the installer to pack the frame square in the opening, fix it firmly to the wall, and seal it all round with a good-quality sealant. Keep the drainage slots at the bottom of the frame clear, and the window will last as long as one bought at full price.

What you never give up

Cheap should never mean unsafe. Every Coetz™ window, new or clearance, has 6.38 mm clear laminated safety glass, which holds together if broken and meets SANS 10400-N, published by the SABS. New windows carry our 5-year warranty on frames, glass and powder coat, and 2 years on hardware and seals; see warranty. Read buying cheap aluminium windows for the hidden costs of buying on price alone.
