Traditional water blasting results in splintering, but our processes protect & restore the wood, reducing slip and ensuring your deck remains in the best condition possible.

Gutter Cleaning

Open-flowing gutters and spouting prevent water from collecting, and leaking along the walls of your property, which can result in damaged exteriors. For this reason, it is recommended you have your gutters cleaned at least once per year to reduce longer-term risk and costs. If not properly maintained, overflowing gutters can lead to leaking and damage your home’s siding, roof or foundations. Full gutters can also be a favourite place of residence for rodents and other pests, so keeping on top of it is crucial. Chemwash Manawatu can handle your gutter cleaning so you don't need to worry about it. Get in touch for a free, no-obligation quote!
