A well-made blind lasts 8 to 15 years, and the mechanism almost always fails before the fabric does. A chain, clutch, cord ladder or motor is a repair costing a fraction of replacement; sun-perished fabric, warped slats and corroded hardware are the faults that genuinely justify a new blind.
Expected Life by Type
| Type | Typical lifespan | Usual first failure |
|---|---|---|
| Aluminium venetian | 10–15 years | Cord ladder wear, bent slats |
| Faux-wood venetian | 10–15 years | Tilt mechanism |
| Real timber venetian | 8–12 years | Finish fading, slat bow |
| Fabric roller | 8–12 years | Clutch or chain |
| Sunscreen roller | 8–12 years | Clutch; fabric outlasts it |
| Vertical louvre | 7–12 years | Carriers and hangers |
| Roman blind | 8–12 years | Cord and ring tape |
| Motorised | 10–15 years | Battery, then motor |
What Actually Shortens It
- UV exposure. The single biggest factor. West-facing fabric on the Atlantic Seaboard ages far faster than the same fabric on a south elevation.
- Salt air. Corrodes cheap hardware within a few years in coastal suburbs. Rust-resistant fittings are worth specifying from the start.
- Cycling frequency. A blind operated several times a day wears its clutch faster than one left in place.
- Wrong material for the room. Real timber in a bathroom will not reach half its normal life.
- Forcing a sticking mechanism. Most broken clutches were dragging for weeks first.
Repair or Replace
The honest split is simple. Repair when the fault is mechanical — a chain, clutch, cord ladder, tilt mechanism, carrier or motor. These are replaceable parts and the blind returns to full function. Replace when the fabric is sun-perished, brittle or discoloured, when timber slats have bowed, or when hardware has corroded through. At that point you are repairing a blind that will fail again next season.
A blind that is simply out of date but working is a decision about the room, not the blind.
Getting the Longest Life
Specify the material for the room rather than the look: aluminium or faux-wood where there is moisture, rust-resistant hardware near the coast, and a fabric rated for the aspect it faces. Dust regularly, using the care guide. And have a sticking mechanism looked at while it is still sticking, not after it has broken — that is the cheapest blind repair there is.
Frequently Asked Questions
Is it worth repairing an old blind?
Yes, when the fault is mechanical. A clutch, chain, cord ladder or motor is a replaceable part and typically costs a small fraction of a new made-to-measure blind.
Why has my roller blind stopped holding position?
The clutch has worn. It is the most common roller failure and one of the cheapest to fix, because the fabric, tube and brackets all stay in place.
Do blinds fade in the sun?
Yes, and it is the main reason fabric is eventually replaced. West and north-west facing blinds fade fastest; darker fabrics and lower-grade materials show it soonest.
