Ivi Sims is one of Australia’s leading experts in timber and wood floor drying and an IICRC Triple Master Restorer, recognised internationally for her expertise in advanced structural drying and moisture management in buildings.

With over 26 years in the restoration industry and more than 15 years specialising in wood floor recovery and Class 4 structural drying, Ivi has become a trusted educator, consultant, and technical authority for restoration professionals, insurers, and flooring specialists.

Ivi holds multiple advanced certifications from both the IICRC and the Restoration Industry Association (RIA), including:

• Water Loss Specialist (WLS)
• Contents Loss Specialist (CLS)
• Certified Mold Professional (CMP)
• Master Fire & Smoke (MSR)
• Master Water Restorer (MWR)
• Master Textile Cleaner (MTC)

In addition to her restoration credentials, Ivi Sims is a recognised Building Scientist with advanced expertise in hygrothermal performance, indoor environmental quality, and building envelope diagnostics. She has completed extensive training through AIRAH (Australian Institute of Refrigeration, Air Conditioning and Heating) in Building Physics and Psychometrics, including advanced studies on airflow, vapour diffusion, and pressure management as they relate to mould and moisture control. Ivi is highly proficient in the interpretation and practical application of the National Construction Code (NCC 2022), Section J and Condensation Management provisions, with a focus on mitigating interstitial condensation, ensuring compliance, and supporting long-term building durability.

Her building science background includes specialised study under Dr. Joseph Lstiburek (Building Science Corporation, USA) and advanced modelling using WUFI hygrothermal software to assess moisture transfer through wall, roof, and timber floor systems in various Australian climate zones. She actively integrates Australian Standards such as AS 1884 (Flooring Installation), AS 1668 (Ventilation in Buildings), and AS 3959 (Construction in Bushfire-Prone Areas) in her consulting and training practice. This deep technical foundation allows Ivi to bridge building design, on-site diagnostics, and restoration frameworks—ensuring that drying, remediation, and moisture management solutions are not only effective but scientifically validated, compliant with Australian regulations, and aligned with international best practice.

Her passion for continual advancement has taken her across the globe, particularly to the United States, where she has trained in the latest drying technologies and presented at industry conferences.

Leadership & Standards Development

Sitting as a board of director Indoor Air Quality Association since 2024 as a active member since 2008 ivi is passionate about Indoor Air quality.

Ivi actively contributes to the development of international restoration standards. She currently serves on:

• IICRC Standards Committees: BSR/IICRC S230 Standard for Professional Inspection of flooring subfloor and substrates, ANSI/IICRC S220 Standard for Professional Inspection of Hard Surface Floor Covering, Field Guides (Health & Safety for Cleaning & Restoration), and Building Moisture Inspection (BMI)
• Australian Standards Committee ME-094: focusing on water damage and mould remediation
• Representative for ATFA: advocating for best practices in timber flooring preservation and restoration

Industry Impact

Passionate about education and sustainability, Ivi champions the importance of wood species identification, correct drying methodologies, and salvaging timber flooring wherever possible. Her work is transforming industry practices by promoting restoration over replacement, reducing waste, costs, and environmental impact.

Ivi is widely respected as a technical leader who continues to drive excellence, innovation, and professional standards in the restoration and timber flooring sectors.
