About MDI
Passive fire protection and construction specialists, making buildings safer and helping duty holders demonstrate compliance.
Fire protection done properly
MDI Fire & Construction Ltd was built on a simple belief: passive fire protection only works when it is installed correctly and evidenced properly. Hidden behind walls, above ceilings and inside risers, it is easy to get wrong and hard to check later, which is why we take such care over the detail.
Our teams bring together specialist knowledge of fire doors, fire stopping, compartmentation, cavity barriers and fire barriers with practical construction skills. That means we can deliver the whole package, from building fire-rated partitions to sealing the services that pass through them.
We work for main contractors, housing providers, facilities managers and building owners across healthcare, education, commercial, residential and industrial buildings, on new builds, refurbishments and live occupied sites.
How we work
The principles behind every project we deliver.
Safety first
Fire protection is life-safety work. We install to tested details, every time, with no shortcuts.
Proof, not promises
Every item is photographed, located and documented so you can show exactly what has been done.
Straightforward
Clear pricing, honest advice and one point of contact from survey to handover.
Quality workmanship
Trained installers who take pride in a neat, compliant and durable finish.
Survey. Install. Evidence.
Survey & Pricing
A passive fire specialist inspects your building, including compartments, doors, voids and service penetrations, recording every defect with photographs and locations. You receive clear pricing linked to each surveyed issue.
Installation
Our trained installers carry out the agreed works, strictly following tested details and the manufacturer's instructions, with minimal disruption to your building and its users.
