What is involved in installing a fire door?

With all of the tools that we have at our disposal to reduce the dangerous results of a fire, the installation of any fire door is a serious matter. A legal requirement in most commercial or accommodation premises and some larger homes – hanging a fire door is a job that must be done in order to stop fires spreading and keep multiple people and buildings safe. Not only you and yours, but the people and buildings that surround too.

What should you expect if you are planning to install a fire door? Fire doors are specially created to prevent fires spreading, so they must be fitted carefully and precisely to ensure that they perform at the optimum level in the event of a fire. Make sure that your fire door is certified and any ironmongery is compatible. You should receive documentation along with your fire door that includes fitting instructions.

How are fire doors fitted?

The fitting of your fire door will involve the attachment of the door frame and door, which must be checked to ensure that the levels and clearance meet the exacting requirements for the door and that the fire door fits within the frame properly. Next the door header will be secured and the gaps around the frame tightly packed with insulating material on every side. Finally the trims will be attached. Once hanging, a fire door safety check need to be carried out, to check that the door closes firmly onto the latch from any angle, all hinges are fitted robustly, there are no bits missing from the door etc.

This is more than the replacement of a standard door. This is distinctly a health and safety measure that could mean life or death, where your fire door will need to pass a fire door safety check. Therefore, you must ensure that the door is installed by an experienced tradesman that has done this many times before and has the documentation to prove it. Please see the FAQs below for further information.

During the fitting of your fire door, it is useful to be aware where additional costs could arise from; further work to the door frame to ensure that your fire door fits properly, any new door frames that may be required, additional tradespeople if necessary to enable the transportation of heavier, wooden fire doors or to physically lift and hang the fire door or the clean-up costs to remove the mess created during the installation. Clearly any additional work and changes will cause your final cost of fitting a fire door to rise, so it is useful to include these possible extras as considerations in your budgets and plans.
