Our Services

We can clean basically anything outdoors!  As well as house washing and exterior commercial cleaning, we also clean decking, concrete, asphalt, cobblestones, bricks & paving stones. We can also treat your roof for lichen, moss and mould, or even clear out your gutters to prevent blockages.  Wooden decks come up brilliantly back from the dull grey or if they are green and slimy. Window cleaning is another one of our services, where we use our pure water machine to clean windows streak free.

House Washing

Chemwash can safely clean all types of houses. We use environmentally responsible detergents to gently emulsify surface pollutants and kill moss, mould & mildew which is rinsed off with water using our low pressure units.

What our clients are saying



Chemwash did an excellent job! The gutters are shining white and the whole area looks brilliant. Thank you for such a well-trained and pleasant person on the job. He was careful with the pressure and I didn’t need to run around the house with towels.
