Chemwash Southland is a locally owned exterior cleaning company in Invercargill, listed in Richmond. It uses a low-pressure system with its own detergents, which the company says were developed by an industrial chemist to be safe for the environment, pets and people. The system rinses at about 600 to 1,000 psi, well below the pressure of most water blasters, which the company says helps avoid damage to surfaces and uses less water. It cleans houses, commercial buildings, shop fronts, concrete, paths, roofs, guttering, fences, decks and outdoor furniture. Services include mould and lichen treatment, roof treatment, gutter clearing, and restoration of fences, decks and concrete. Quotes are free and carry no obligation.
The company was founded in 2017 by Gregor Morsink, whose family also runs a painting business, and it is part of the national Chemwash Cleaning network. The website says the washing helps paint last longer, and that a clean exterior also means fewer weekend jobs for the owner.
