Iron Door Installation Requirements: What to Confirm
t413-33

Before ordering an iron door, confirm the exact opening size, the condition and type of the wall or frame it will fit into, and how the door will be fixed and finished on site. Checking access, floor level and the swing direction in advance prevents delays and rework during fitting.
Confirm the Opening Dimensions
The most important requirement is an accurate opening. Measurements should be taken at the actual site, not from plans, because walls are rarely perfectly square or plumb. Record the width and height at the top, middle and bottom, and note any variation.
- Clear opening width and height
- Depth of the wall or reveal
- Floor finish, including tiles or screed still to be laid
Tell the fabricator whether the final floor finish will change the height, since this affects the required clearance.
Check the Wall and Frame Condition
The structure around the door must be solid enough to carry the fixings and the weight of the leaf. Confirm that the masonry or concrete is sound, free of loose plaster, and that any existing frame is straight and secure. Damaged reveals should be repaired before the door is set, not after.
Points to check
Look for cracks, moisture, and surfaces that are out of plumb. Discuss with the installer how the frame will be anchored to the wall, and whether the work requires drilling into concrete or stone.
Plan the Swing and Clearances
Decide the swing direction, inward or outward, and whether the door opens left or right. Make sure the leaf has room to open without hitting furniture, radiators, light switches or the handrail of a staircase. Allow for the threshold and any mat or floor covering that will sit under the door.
Confirm the required gaps around the leaf with your installer, as these depend on the door type and the site. Exact tolerances are settled with the installer for your specific opening.
Confirm Site Access and Handling
A finished iron door is heavy and must be carried into the building, sometimes up stairs or through narrow corridors. Confirm the route from the street or lift to the opening and check that the door will fit through every point along it. Ask whether the building has a lift and whether any doors on the route need to be removed temporarily.
- Route width and height
- Stairs or lift size
- Parking or loading space for the delivery
Prepare Power and Hardware Needs
If the door includes an electric lock, intercom, access control or automatic closer, confirm the cabling route and power point before installation. It is much easier to run conduit while walls are still open. Check which lock cylinder and handle types are included and whether you have a preference, so that the hardware is fitted correctly the first time.
Agree on who is responsible for chasing cables and making good any plaster afterward.
Agree on Finishing and Installation Timing
Confirm the finish you want, such as galvanized and powder-coated surfaces or a specific colour, and whether it should be applied before or after fitting. Plan the installation after heavy wet trades like plastering and tiling are complete, to avoid damaging the finish. Ask the installer to confirm the sequence of steps and who will clean up and protect the door on completion.
Frequently asked questions
Do I need to measure the opening myself before ordering?
Yes, it is best to measure on site, since walls are rarely perfectly straight or square. Your fabricator can confirm the measurements during a site visit before production starts.
Should the floor be finished before the door is installed?
Ideally, yes, because the final floor level affects the door height and clearance. If the floor will change later, tell the fabricator so the leaf can be sized correctly.
What if the existing frame is damaged?
Repair or replace the frame before the door is fitted, because the door depends on a solid, true structure. Discuss the options with your installer before ordering.
Can the door be installed without drilling into the wall?
Usually fixing requires anchoring into the wall or reveal, so some drilling is normal. Confirm the method with your installer, especially if the wall is stone or thin.
Common mistakes to avoid
The most common mistake is ordering from a single rough measurement taken before the floor and wall finishes are complete. Skipping the site check of access routes and swing clearance also causes costly delays.
Our recommendation
Have the installer visit the site before production, and ask them to write down the opening sizes, swing direction, floor level and access route in one confirmed specification.
Summary
Confirming the opening, wall condition, swing, site access, hardware wiring and finishing sequence before ordering makes installation of an iron door smooth and avoids rework.
