3 Reasons DIY Water Blasting Can’t Compete with Chemwash

Published on: February 20th, 2024

Wash your home safely and efficiently without risking damage.

Across New Zealand, we love to embrace the DIY spirit, whether tackling a tricky ladder, using a water blaster, or sacrificing a precious weekend. However, when it comes to your property – a long-term investment – cutting corners with exterior cleaning can lead to unforeseen consequences.

At Chemwash Wellington, your property is our priority. We are committed to delivering excellent results and providing an unmatched service experience. Let us help you avoid potential issues and ensure you have a magical summer!

Risk of Surface Damage

DIY water blasting uses high-pressure water, often removing mould, grit, and dirt, but it can also strip away protective coatings and force water into cracks, potentially causing damage, reducing the life of your paint, and risking water damage behind your home’s cladding.

Chemwash uses specialised low-pressure equipment, reducing water usage by 50% compared to DIY high-pressure water blasting. Instead of relying on pressure, our tested pet-friendly detergents do the heavy lifting.

Height Safety

Cleaning high and hard-to-reach surfaces can be dangerous, especially when using ladders and dealing with slippery surfaces. WorkSafe reports that around 70% of all falls in New Zealand occur from ladders and roofs, most of which happen at residential properties. More than half of these falls occur from a height of less than three metres.

Our exterior cleaning experts have the necessary skills, tools, and approved safety equipment for a secure process.

Our experienced team takes pride in being members of the Exterior Cleaning Industry Association, ensuring top standards and industry credibility. We regularly update our health and safety protocols to ensure the safest possible working conditions for our team and your property.

Time Efficiency

High-pressure washing your property is time-consuming, often taking up your entire weekend. However, when you work with Chemwash, you’re opting for specialised equipment and our efficient, eco-friendly processes, allowing you to free up your schedule for other, more enjoyable activities.

Our soft wash cleaning methods ensure even results without damage, saving you from costly repairs and confidence that the job is done right the first time.
