Mould Removal
Our mould removal service tackles infestations at their source using advanced, non-invasive techniques. We employ Goldmorr-certified products to eliminate mould without damaging surfaces, often avoiding the need for repainting. The process includes forensic inspection, spore fogging, and detailed reporting to ensure complete remediation and prevent recurrence.
Air Quality Improvement
This service enhances indoor air quality through comprehensive mould spore elimination and pollutant reduction. Using GM2000 fogging technology, we neutralise airborne contaminants while providing WHO-standard compliance reports. The treatment addresses hidden biofilm in HVAC systems and reduces asthma triggers and allergens for improved respiratory health.
Bio Clean
Specialised biofluid decontamination for vehicles and facilities using non-toxic, biodegradable solutions. Our technicians eliminate pathogens like Hepatitis and HIV from emergency service vehicles, employing ATP swab testing to verify 99.9% bacteria reduction. The process includes on-site sanitation facilities for client convenience.
Cool Room Sanitising
Industrial cool room cleaning that restores energy efficiency and food safety. We remove biofilm from evaporators, clean condensers, and apply hydrophilic coatings to reduce energy consumption by up to 20%. Comprehensive reports document temperature improvements and airflow metrics, with annual maintenance plans available.
HVAC Room Cleaning
Full HVAC system sanitisation that improves air quality and reduces energy costs. Our process includes carbon filter installation, anti-static coating application, and thorough equipment cleaning. We address environmental factors like traffic emissions affecting system efficiency, with before-and-after performance documentation.

Questions
What health risks does mould pose?
Mould releases spores that can cause respiratory issues, asthma exacerbation, and allergic reactions. Our remediation reduces these risks by eliminating spores and improving air quality.
How does your mould removal process work?
We follow a three-step process: forensic inspection to identify sources, targeted removal using Goldmorr products, and spore fogging to prevent regrowth, with detailed compliance reporting.
Can mould return after treatment?
Our fogging technology eliminates 99.9% of spores. We also provide prevention strategies like humidity control to minimise recurrence risk, backed by a limited warranty.
Do you service commercial properties?
Yes, we handle government buildings, healthcare facilities, and industrial cool rooms. Our services include compliance documentation and scheduled maintenance plans.
Are your products safe for families?
We use non-toxic, biodegradable Goldmorr solutions safe for children, pets, and immunocompromised individuals. Many clients with health conditions report symptom improvement post-treatment.
How long does treatment take?
Most residential jobs complete in one day. Commercial HVAC or cool room treatments may require additional time, with clear timelines provided during quoting.

Oct 03, 2020 Report
My tenant failed to report condensation and mould problems for over a month after first noticing them and only because we contacted them re a pura tap filter change. When they decided to report it they suddenly considered it to be incredibly dangerous and urgent. I called Barry late on Thursday afternoon. Barry agreed to rearrange his schedule to have my rental property treated the very next morning.

My tenant complained even though I couldn't determine if any of the tiny remaining spots they photograhed were actually mould. I left a message for Barry when I received their complaint on Sunday morning

I recently contacted Barry as we needed urgent help with an investment property and a difficult tenant. The service that was provided from the very first phone call was phernominal! Barry changed things in his schedule to help us out last minute and his reassuring demeanor helped more than words can say. I would recommend his services to anyone who asked! Thank you Barry!
