You’ve probably seen efflorescence even if you don’t realise it. Because the Great British weather is so varied, our homes go through lots of different temperature changes.

Things like high levels of rain, moist conditions, low temperatures and pooling groundwater can lead to white deposits (efflorescence) appearing on the bricks of your new home.

Watch our video below to learn more or read on for more information about dealing with efflorescence in your new home.

Is efflorescence harmful?

Efflorescence can happen to any building and isn’t a fault. It’s completely natural and is nothing to worry about. It’s also only temporary and will eventually disappear, so you don’t need to worry about the integrity of your home.

What causes efflorescence?

Wet weather causes porous bricks to absorb moisture. Rainwater then mixes with salt and minerals inside the brick. As brickwork dries, this moisture evaporates, leaving the salt and minerals to crystallise. This leaves those harmless white deposits on the outside of the brick.

For this reason, efflorescence usually occurs most in brickwork that’s particularly exposed to the elements and moisture.

How to remove brick efflorescence

You can remove efflorescence deposits from brick by scrubbing with a dry stiff brush, ideally in warm weather. Or simply wait for rainwater to wash away efflorescence marks.
