For mould to grow on concrete, the temperature does not have to be humid.

For example, during the cooler winter months, and as the temperature drops, the cooler surface of the concrete and most outside surfaces will cause a build up of condensation. Just like condensation forms on plants and lawn, it also forms on concrete creating the perfect environment for mould to grow.

In time and as quickly as the 3 month period over winter, this creates an environment ideal for mould to form at an accelerated growth. Its this very reason that unlike the warmer and more temperate months in Spring and especially Summer, that having your surfaces cleaned in Winter is a must to tackle and prevent the ongoing formation and build up of mould.

The reason most people don’t address the mould problem in winter is simply, like a lot of us, we don’t entertain or spend as much time outside in Winter as we do in the warmer and more pleasant months like Spring and Summer.

A lot of people unfortunately wait for the warmer months to undergo a professional pressure clean, but having it done before in the cooler months can put a stop to the mould spreading and taking over.

It also prevents the inconvenience of rushing around to get the surface cleaned at the last moment, especially if its your pool, Alfresco or patio area you need ready for Spring and Summer entertaining. How many of us have simply avoided using our favourite outdoor area because its become dirty, slippery and not at all inviting for entertaining family and friends.

Having your favourite area professionally pressure washed before the warmer months, will mean only having to spend very little time and effort in maintaining the surface after the initial clean. This is simply achieved by using a leaf blower and garden hose as explained in our blog How Can I stop and Slow Down Mould From Returning.
