Fire door hold-open devices in Isleworth: what's involved
Looking for fire door hold-open devices in Isleworth? We supply and fit certified fire doors and components across Isleworth and the wider Greater London area, working from a free survey and a fixed written quote.
Buildings in and around Isleworth range from shared houses to student accommodation and clinics. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Free-swing closers suit Isleworth settings where residents or pupils find doors hard to open. Where doors in Isleworth care homes, schools or offices are being wedged open, a hold-open device is the safe fix.
Types of hold-open
Electromagnetic door holders are wall or floor magnets wired to the fire alarm. Hold-open closers combine the closer and the hold-open in one unit. Free-swing closers let the door move freely and close it on alarm. Some battery units listen for the alarm sound; these must be suitable for the alarm system and the building. The right choice depends on the door, the alarm and how people use the space.
What you get:
- Release testing with the alarm
- Electromagnetic holders to BS EN 1155
- Coordination of alarm interface
- Hold-open and free-swing closers

Questions
Is Isleworth within your coverage area?
It is. We cover Isleworth in Greater London and neighbouring towns such as Hounslow. There is no charge for the survey.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
Is it legal to wedge open a fire door?
Wedging a fire door open defeats its purpose and is likely to breach the duties under fire safety law. A hold-open device that releases on alarm is the safe alternative.
Who tests hold-open devices?
They should be tested with the fire alarm as part of the routine testing arrangements. We test them at installation and record the results.
