The most common blind defects and what they mean
Blinds are mechanically simple but precise systems, so typical failures are easy to classify. Most repairs in our daily work concern five defects:
- 01The motor no longer responds: often a defective drive or a disturbed radio connection. Motors can be replaced individually.
- 02The blind hangs crooked: usually a torn lifting tape or a shifted winding shaft. A classic, very repairable fault.
- 03Individual slats are bent: after hail or impact. Slats can be replaced individually as long as the profile is still produced.
- 04The blind jams in the guide rail: dirty or warped rails, often after facade work. Cleaning or straightening is usually enough.
- 05The strap is frayed or torn: a standard case on older strap winders, fixed in under an hour.
What does a blind repair cost?
Most repairs range between CHF 150.– and CHF 600.–, including travel and labour. A strap replacement sits at the lower end; a motor replacement with programming costs between CHF 400.– and CHF 700.– depending on the drive. For comparison: a new slat blind with installation starts at around CHF 1'200.– per window depending on size.
A fixed price after diagnosis matters. Reputable companies quote a binding price after a short on-site inspection, before work begins. That lets you compare repair and replacement on an honest basis.
The rule of thumb: age, condition, spare parts
Three questions decide almost every case. First, age: blinds last 20 to 30 years under normal use. If your system is younger than 15 years, repair almost always wins. Second, the condition of the substance: as long as guide rails, housing and curtain are intact, motor, strap and individual slats can be replaced economically. Third, spare-part availability: parts for common systems of the last two decades are readily available, including across brands.
It gets critical when several factors combine: a system over 25 years old with warped rails and slats that are no longer produced. Here every repair only delays the inevitable, and the money is better invested in a new system, especially since modern blinds insulate noticeably better and integrate with smart homes.
When replacement really pays off
Replacement pays when repair costs exceed 40 to 50 percent of a new system, when defects accumulate, or when you are renovating anyway: a window replacement or facade renovation is the ideal moment for new blinds, because scaffolding and coordination are already paid for.
Comfort gains count too. New systems run quieter, shade more precisely and can be operated with sun and wind automation. If you are out during the day, automatic shading prevents rooms from heating up before it happens.
How we work in Zurich and the region
We inspect every system on-site, quote a fixed price and tell you honestly when a repair is no longer worthwhile. Around half of our repair orders concern systems from other manufacturers; we carry common spare parts in our service vehicles. In the city of Zurich and the Limmat Valley we are usually on-site within two to three working days.
