Professional House Washing in Hamilton & Waikato
Hamilton's climate, warm summers and wet winters, creates ideal conditions for mould, algae, and lichen to take hold on your home's exterior. Left untreated, this buildup doesn't just look bad — it works into your cladding and paintwork over time, causing damage that's expensive to fix. We use soft washing to remove it properly and protect your home in the process.

Everything That's Included in a Professional House Wash in Hamilton
Why Soft Washing Beats High-Pressure Cleaning
High-pressure washing forces water behind cladding, strips paint, and cracks plaster, especially on older Hamilton homes. Soft washing uses low pressure combined with a professional-grade cleaning solution that breaks down mould, algae, and grime at the surface level. The result is a deeper clean that actually treats the problem rather than just blasting the visible layer off.
What We're Actually Removing From Your Home
The green and black growth you see on exterior walls isn't just dirt, it's typically a combination of algae, mould, lichen, and sometimes moss. Each type bonds to your surface differently and needs to be treated correctly to be fully removed. Left long enough, these organisms break down paint coatings and work into porous surfaces like plaster and timber, leading to costly repairs. Catching it early and cleaning it properly is significantly cheaper than replastering or repainting.
What Happens on the Day of Your House Wash
We start by assessing your cladding type and the condition of the exterior before applying anything. Different surfaces, weatherboard, plaster, brick, cedar, respond differently, so we adjust our solution strength and pressure accordingly. The cleaning solution is applied and given time to work before being rinsed off at low pressure. We cover windows, outdoor furniture, and garden beds to protect them during the process. Most standard Hamilton homes are completed within a few hours.
Hamilton's Trusted House Washing Team
MJ Exterior Cleaning is owned and operated by Max and Josiah, two Hamilton locals who built this business on doing quality work and treating every property with care. You deal directly with us from quote through to completion.
Our gear is fitted out specifically for exterior soft washing, we use wide-fan, low-pressure nozzles that apply an even rinse across walls and eaves without blasting or leaving patchy marks. We also pre-soak dry surfaces to help avoid streaking, and tape off power outlets, locks, or anything that shouldn't get wet. It's a bit more work, but it makes a difference in the end result. Our team shows up ready, cleans with care, and doesn’t rush through just to move onto the next job. Whether we’re working on a weatherboard rental, a rendered two-storey, or a small commercial space, you can expect a solid result that lasts longer, and a house that actually looks looked after when we’re done.
