Preparing your awnings for winter.
Prevent them from freezing solid and avoid storm damage.

Retract them whilst dry and do not operate them in frost – this will ensure your awning survives the winter.

You prepare awnings for winter by cleaning them before the cold season, retracting them whilst dry and not operating them in frosty conditions – because a damp awning will freeze solid in the casing and tear when extended. If you also check the automatic wind sensor, you’ll be prepared for winter storms too. Griesser Awning Service is there to help if anything does go wrong. Swiss service since 1882.

What causes problems for awnings in winter.

These four risks are most common during the colder months – with the right preparation, you can avoid them.

Freezing

A damp or icy blind freezes to the box or in the guide and tears when pulled out.

Wet snow & winter storms

Heavy, wet snow and gusts of wind take a heavy toll on freestanding awnings and screens.

Moisture & Mould Stains

Fabric that has become damp can develop mildew stains over the winter, which are very difficult to remove later on.

Iced-up mechanism

Dirty, damp guides and joints can freeze up and block the blind.

The winter checklist
in 5 steps.

Here’s how to winterise your blinds. The most common type of winter damage occurs when a damp or icy blind is operated and the frozen fabric tears as it is extended. The rule is therefore: in frosty conditions or when ice is visible, do not move the blind until it has thawed.

With this checklist, your sun protection will get through the winter safely.

Clean and store whilst dry.
Clean it one last time before winter and allow the awning to dry completely before storing it – this prevents mildew stains and the awning from freezing solid.

Do not operate in frosty conditions.
If the blind is damp or iced over, do not move it until it has defrosted – otherwise the frozen blind will tear.

Check the automatic wind sensor.
Check that the wind sensor and automatic mechanism are working properly so that the awning retracts automatically in the event of gusts of wind.

Check the guides.
Remove any dirt from the guide rails and joints to prevent them from freezing up and becoming blocked.

Retract during a storm.
As a precaution, retract manual awnings when a storm is forecast – they are best protected when retracted.

Answers to your questions

All about blinds in winter

How do I prepare my awnings for winter?

Clean them before winter, retract them whilst dry, and do not use them in frosty conditions. Also check the automatic wind sensor and other sensors to ensure the awnings retract automatically in stormy weather.

What should you do if the shop is frozen solid?

Do not use until it has completely defrosted. Extending it whilst it is still frozen may damage the fabric, slats or mechanical parts.

Do I need to retract my awning in winter?

Yes. When retracted and dry, the awning is best protected against damp, frost and strong winds. A cassette housing provides additional protection for the fabric and mechanical components.

Can I clean my blinds in winter?

It’s best to clean them in autumn when the temperatures are mild, and let the curtains dry completely. Otherwise, frost will cause ice to form, and fabric that’s been rolled up whilst damp will develop mildew stains.

Who pays for damage caused by frost, storms or hail?

Permanently fitted awnings are classified as natural hazard damage in Switzerland and are often covered by building or home contents insurance. Cover and excess amounts vary from case to case – please check the terms and conditions with your insurer.
