Chemwash Top of the South

New Zealand's leading building and house wash
exterior cleaning company.

We Clean Buildings & More

Locally owned and operated, Chemwash was the first company in New Zealand to utilise the combination of formulated detergents and a low pressure, unique fan washing procedure to rinse away dirt, grime and build-up. Our low-pressure system is specialised for washing and cleaning of all exterior surfaces. We effectively clean houses, commercial buildings, shop fronts, concrete, paths, guttering, roofs, fences, wooden decking, outdoor structures and more.

We live in a remarkable environment that thrives in the growth of microscopic organisms. Having the exterior of your property Chemwashed removes those unsightly growths, and inhibits them from re-establishing. While extending the life of the surfaces, we also prevent them from becoming compromised, by coating and eliminating the spores which can impact your health.

What our clients are saying

Cheryl

Riverlands, Blenheim

Just wanted to send you a big thank you for the wonderful job you did at our place today. The windows have been a bit of a worry as I haven't been able to do then for some time. The gutters had an amazing clean-out as Graham may not be able to do jobs like that again and the house walls look great.
