Quality Blinds Online in South Africa: How to Tell the Difference Before You Buy

Made-to-measure vs standard sizes

The single biggest quality indicator when buying blinds online is whether the blind is manufactured to your exact window measurements or sold in standard sizes (600mm, 900mm, 1200mm increments).

Standard size blinds are cheaper because they are mass-produced. But they never fit perfectly. A blind that is too narrow leaves light gaps on the sides. A blind that is too wide needs cutting, which voids the warranty on most cheap brands. A blind that is too short does not reach the sill.

Made-to-measure blinds are manufactured after you place your order, to the exact millimetre dimensions you provide. They fit the window, not the other way around. The Custom Blinds online shop manufactures every blind to your exact measurements with free delivery nationwide.

How to check fabric quality before buying

Online product photos make every fabric look good. The difference between a quality fabric and a cheap import only becomes apparent after installation, when UV, humidity, and daily use start testing the material.

Check the manufacturer name. Quality online retailers name their fabric suppliers. Custom Blinds uses Hunter Douglas and Coulisse fabrics, both tested for Southern Hemisphere UV intensity. If the retailer cannot tell you where the fabric comes from, it is likely a generic import with no UV rating.

Check the UV stabilisation rating. Quality roller blind fabric is UV stabilised to resist fading and degradation. In South Africa, where UV levels are among the highest in the world, untreated fabric fades visibly within one to two summers.

Check the fabric weight. Heavier fabric (measured in grams per square metre) generally indicates better construction. Cheap blockout fabric uses thinner backing layers that can delaminate over time.

Brackets, chains, and mechanisms: where cheap blinds fail

The fabric is what you see. The brackets, chains, and roller mechanism are what determine whether the blind still works smoothly in three years.

Brackets: Metal brackets (aluminium or steel) hold the blind securely and withstand the torque of daily operation. Plastic brackets crack under stress, especially in heat. If the product listing does not specify the bracket material, assume plastic.

Chains: A quality bead chain operates smoothly with consistent tension. Cheap chains develop stiff spots, skip beads, and eventually jam. In humid coastal environments, uncoated chain mechanisms corrode and seize.

Roller tube: The aluminium tube inside the blind headrail should be thick enough to resist bending on wider spans. Cheap blinds use thin-walled tubes that sag in the middle on spans over 1.5 metres, causing the fabric to bunch unevenly.

What to look for in an online blind retailer

Instant pricing: You should see the exact price for your blind before you buy. If the retailer requires a quote request for standard products, the pricing is likely inconsistent or inflated.

Clear measuring instructions: A quality retailer provides detailed measuring guides because they know that fit depends on accurate dimensions. Custom Blinds’ measuring guide covers every window type with illustrations.

Named fabric and component brands: Transparency about materials indicates confidence in the product. Vague descriptions like “premium fabric” or “high quality components” without naming the manufacturer are marketing, not specification.

Guarantee or warranty: Look for specific commitments. “Satisfaction guaranteed” is vague. “Too big, we trim free. Too small, 5% off replacement” is a real guarantee with real consequences for the retailer.

Free delivery as standard: Delivery should be included, not used as a promotional hook. Custom Blinds delivers free nationwide on every order, every day.
