Intumescent Coating Inspection – Passive Fire Protection You Can Trust

Thin-film intumescent coatings play a vital role in the passive fire protection of structural steelwork, offering life-saving resistance by maintaining the integrity of a structure for a specified duration during a fire. These specialist coatings are engineered to expand when exposed to high temperatures, creating an insulating barrier that slows heat transfer and helps preserve the steel’s load-bearing capacity. Designed to last for the entire life of a building, their correct application and condition are absolutely critical to both safety and regulatory compliance.

However, the performance of intumescent coatings is entirely dependent on correct selection, preparation, and application, and the consequences of poor workmanship or oversight can be catastrophic, putting lives at risk and potentially invalidating fire safety certifications and insurance.

At M.H. Inspection Ltd, we are proud to be recognised as one of the UK’s leading authorities in the inspection, testing, and verification of intumescent coating systems. With decades of experience in the protective coatings industry, we offer a range of tailored services to support clients in construction, infrastructure, and asset management:

Our Services Include:

• Full documentation review of specifications, product certification, and application procedures
• Full-time or part-time on-site inspection by qualified professionals
• Complete project oversight, including quality assurance and technical support from start to finish
• Independent verification of existing intumescent coatings through sample analysis and detailed site surveys
• Issue of a Coating Condition Certificate, confirming the coating is of the correct type, properly applied, and in fit-for-purpose condition

Having one of our experienced, certified inspectors embedded in your team ensures potential issues are identified and addressed before they escalate. Early intervention can significantly reduce delays, rework, and associated costs — all while ensuring your passive fire protection measures remain compliant and fully functional.

Where an existing intumescent system requires verification, our inspectors can attend site to carefully extract samples for laboratory testing, conduct a thorough condition survey, and provide photographic evidence of any areas requiring remedial work. Upon satisfactory analysis and completion of any necessary corrections, we will issue a Coating Condition Certificate to document the system’s compliance.
