Frequently asked questions about fire door installation in Harpenden

What is the difference between FD30 and FD60 fire doors in Harpenden?
FD30 doors provide 30 minutes of fire resistance and are suitable for most commercial and residential applications. FD60 doors provide 60 minutes of resistance and are required in higher-risk locations such as escape stairwells. For Harpenden sites, we confirm the exact recommendation during survey because building layout, occupancy and local authority or insurer requirements can change the specification.
Can you replace fire doors in occupied buildings in Harpenden?
Yes. We regularly carry out fire door replacements in occupied offices, schools, and residential buildings with minimal disruption to your operations.
Do fire doors need to be self-closing in Harpenden?
Yes. All fire doors must be fitted with a self-closing device. The only exception is where electromagnetic hold-open devices are linked to the fire alarm system.
Do you cover the whole of Harpenden?
Yes. Our engineers cover all of Harpenden and the surrounding Hertfordshire area. We provide free site surveys and can typically attend within 24–48 hours of your enquiry.
