House Washing Wellington

Chemwash is New Zealand's leading house wash company.  Chemwash also cleans commercial building's and all exterior surfaces.  No need for high pressure water blasting, the Chemwash system uses low pressure (soft wash) and is specialised for washing & cleaning of all exterior surfaces.  We wash houses, commercial buildings, shop fronts, concrete, paths, guttering, roofs, fences, decks, outdoor furniture, outdoor structures and more.


The Chemwash system is safe for people, pets, and plants.  We never use harsh chemicals or high pressure water blasting.


We are 100% locally owned and operated. We were the first company in NZ to use the combination of detergents, low pressure and a then unique fan washing procedure.


A little about us..


26th year in business

We are a family run business run locally out of Porirua, we opened our doors in April 1990 and have been washing houses in Wellington ever since.  We would like to think our slogan "we care for your property as much as your do" sums up our company, we are small enough to take notice of those little extra things, but big enough to handle any sized project you can throw at us.


Moving with technology

Technology these days seems to move forward at a super sonic speed and we are keeping up!  We have just introduced a new online system which allows us to get your quote to you faster than ever before, sometimes you will have the quote in your email inbox before we have left your property!


Extra add-on services

Due to popular demand we started a Pest Control service a number of years ago, this has had a fantastic response over the years with our customers who have spider, insect or fly problems, a simple annual spray and problem solved.

Since then we have also added to our artillery of services a Carpet & Upholstery Cleaning service, choose our 8 stage deluxe carpet clean and you won't be disappointed.

More recently we have included a Interior Cleaning service, we can quote for on-going weekly cleans, one off spring cleans, moving out cleans or big commercial cleans.  We have just invested in steam extract cleaning technology which means no harsh chemicals are needed.



The proof is in the pudding
