Matters Needing Attention in Cleaning Exterior Wall

2019-12-23




Over time your outside walls can become soiled. Things like pollution, dirt, dust, leaves, pollen, mildew, mould, cobwebs and bird or bat poo can all accumulate and make your walls look old and dirty. Cleaning your exterior walls may sound like a massive task, but they should ideally be taken care of at least once or twice a year.Regular cleaning makes the job easier, keeps your house looking great, and gives you the opportunity to check on whether there are any repairs or maintenance issues that might need attending to.
Before you begin washing your walls you should:
Check windows, roof, and exterior moulding and note any repairs necessary.
Clear gutters.
Trim back any overhanging branches or shrubs that lean against the walls.
If you’re not using a pressure cleaner you will either need an attachment for your garden hose, or a long handled broom and ladder. Wash the walls from the top down, so that you're not letting dirt run down over bits you've already cleaned. If you're using detergent, you should wash the walls a second time with plain water to rinse off any residual soap.
If your walls need mould or mildew removed, try scrubbing the affected areas with borax and water. Bleach will also kill mould but can be harsh on you and the environment. If you choose to use bleach, wear old clothes and protective goggles and breathing gear. Water any plants near your walls first - this will stop them absorbing too much bleach. If your plants are especially sensitive, consider adding a small amount of limestone to your garden to neutralise the acidity of the bleach.
