Cleaning Mold and Mildew Off Bricks

Bricks are strong, durable and built to last and one could be forgiven for believing they are completely maintenance free. Unfortunately, this is not the case and many Auckland property owners have learned this the hard way. Reclaimed bricks are often used for creating courtyards, patios, and walkways.  They look crisp and elegant when they are first laid but when left to the elements they can become tired and drab as shown in the picture to the right.

Moss, mold, and mildew will quickly spread and spoil the general appearance unless some maintenance is carried out from time to time. Cleaning your bricks will help maintain their original elegance and prolong the life of the bricks.

Serious cleaning should be undertaken at least once per year to keep your property looking like new and to protect the bricks from degradation.

Imagine arriving home at the end of a hard days work - which option would you prefer to be greeted with.  One option provides you with an uplifting sense of pride whilst the other provides a nagging reminder that you will need to do something about it very soon or it will continue to deteriorate.

Useful Tips for cleaning Mold, Moss and Algae.

Mold, Moss and Algae are most prevalent in damp areas where water pools and the sun struggles to reach.

If you're starting to notice a buildup of mold or algae on the exterior surfaces around your home and you have the time to take care of the problem yourself, then here are a few tips to help you get the problem sorted.

  • Let the sunshine in. Areas that are heavily shaded due to overgrown shrubbery will need to be trimmed back to ease the problem. Sunlight is a natural remedy for moss, mold and algae.
  • Once the area has dried out completely, use a stiff yard broom and give the whole area a good sweeping.
  • Waterblasting is often the most effective method for removing mold, moss and algae from pavers, bricks and concrete. If you do not own a water blaster, you can hire one or get a specialist company to wash your surfaces for you.
  • Preventing Future Mold and Algae Problems
    After the infected area has been all cleaned up, make sure the area can dry out regularly. This will probably involve pruning all overhanging tree foliage and shrubs, moving patio furniture and creating efficient drainage to avoid pooling water.
