Vacant buildings are easy targets for vandals, squatters, and thieves. Steel security for doors and windows provides an immediate, visible deterrence and robust protection for unoccupied premises. At Marpol Security, we install high-strength steel solutions to secure entry points and safeguard vacant properties from intrusion, damage, and liability.
All our boarding is steel as standard, offering superior strength and durability compared to timber or plastic alternatives.

Unprotected doors and windows are often the first point of entry for break-ins. Once access is gained, the risks escalate quickly — from vandalism and arson to theft and illegal occupation.
Steel security solutions are a fast, effective way to:
Block unauthorised access
Deter opportunistic damage or occupation
Secure a site after an eviction or break-in
Maintain insurance compliance for vacant buildings
Minimise repair costs and downtime
