Awning Buying Guide – Things to Know Before Installing an Awning

Installing a patio awning is a great way to create shade and extend your outdoor living space, making patios, terraces and garden seating areas more comfortable throughout the warmer months.

Before installation, there are a few important things to understand about how awnings work, including rain run-off, wind resistance, installation requirements and how the awning is fixed to your property.

This guide explains the key things to know when choosing an awning so you know what to expect during the survey and installation process. Understanding these points helps ensure the awning you choose is suitable for your property and performs reliably for years to come.

At John’s Blinds, every awning installation begins with an initial enquiry. We usually ask customers to provide a few photos of the area and some basic details about what they are looking for. This helps us understand the space and advise on the most suitable options before arranging a survey.

Once we have reviewed the information, we can arrange a site survey to take measurements, assess the installation surface and confirm the best positioning for the awning.

Patio Awning Guide

Retractable awnings are designed to provide shade from the sun and can also offer protection from light rain. However, they should always be retracted during strong winds, heavy rain or snow to prevent damage.

Many customers choose to add wind sensors, which automatically retract the awning if wind speeds increase.

When an awning extends, the fabric projects outward from the wall to provide shade. However, the shaded area created will usually be slightly less than the full projection because the awning is installed at an angle to allow rainwater to run off.

For example, an awning with a 3m projection will not provide a full 3m of horizontal shade. The actual shaded area will depend on the installation height and pitch of the awning.

During the survey, we will discuss the available projection sizes and help you choose the most suitable option to provide the shade coverage you want for your patio or seating area.

Retractable awnings can provide protection from light rain, but they must be installed at the correct angle so rainwater can drain away.

To allow water to run off properly, awnings typically require a minimum pitch of around 14°. If the angle is too shallow, rainwater may collect on the fabric, which can place unnecessary strain on the awning.

For this reason, the mounting height must be sufficient to allow the correct pitch, which will be assessed during the survey.

All awnings are made specifically for your property following a survey.

During this visit we measure the installation area and check:

• available width and projection

• fixing positions

• mounting height

• obstacles such as lights, gutters or pipes

This ensures the awning fits correctly and operates safely.

Awnings are fixed directly to the structure of your property, typically brick or concrete.

During the survey we assess the wall construction to ensure it can safely support the awning.

In some cases specialist fixings or alternative mounting positions may be required.

Awning fabrics are technical outdoor textiles designed to perform in sunlight and changing weather conditions.

Because of the way these fabrics are woven, it is normal to occasionally see:

• slight rippling in the fabric

• small pinholes visible in strong sunlight

• minor creasing

These characteristics are natural and do not affect the performance or durability of the awning.

Most modern awnings are motorised and operated using a remote control, which means a nearby electrical supply is required.

During the survey we will check the location of the power source and discuss the best routing for the cable. If a suitable supply is not available, an electrician may be required before installation.

Retractable awnings are designed to withstand normal outdoor conditions but should always be retracted during strong winds.

Many awnings are tested to European wind resistance standards (EN 13561), which classify how well the awning performs in wind.

For additional protection, optional wind sensors can automatically retract the awning if wind speeds increase.

Most modern awnings are motorised and operated using a remote control.

Additional options may include:

• wind sensors

• sun sensors

• smart home integration

• integrated LED lighting

These features can make the awning easier to operate and allow it to respond automatically to changing weather conditions.

Awnings require very little maintenance, but a few simple steps will help keep them looking their best and extend their lifespan.

Keeping the fabric clean and ensuring the awning is fully dry before retracting will help maintain the fabric and mechanism.

If the awning is accidentally retracted while the fabric is wet or damp, it should be opened again at the earliest convenient opportunity to allow the fabric to dry naturally. This helps prevent moisture from remaining within the folds of the fabric.

Occasional cleaning will also help keep the awning looking fresh. Most awning fabrics can be cleaned using warm water and a mild soapy solution, applied with a soft brush or cloth. Avoid harsh chemicals or pressure washing, as these may damage the fabric coating.

It is also advisable to occasionally check the awning cassette or folding arms for leaves, dirt or debris, particularly during autumn months. Removing any build-up will help ensure the awning retracts smoothly and protects the fabric when closed.

Regularly retracting the awning during strong winds or severe weather will also help protect the frame, mechanism and fabric.

For most homes, planning permission is not usually required for awnings. However, it may be necessary for:

• listed buildings

• flats or apartments

• conservation areas

• commercial premises

If required, the customer is responsible for obtaining any necessary permissions before installation.

Every awning installation begins with a professional survey to ensure the correct size, position and fixing method.

Our team will guide you through the available options so you can choose an awning that suits both your property and how you plan to use your outdoor space.
