Fire Door Repairs in Bow

Fire Door Repairs Bow: What Most People Get Wrong First

Fire door repairs jobs in Bow come through to us every week, and more often than not, the person calling has already tried to sort it themselves - or worse, had a general handyman look at it. That's usually how a straightforward repair turns into a bigger problem.

The thing most people miss is that a fire door isn't just a door that happens to be heavy. Every part of it works together. So when something looks like a simple cosmetic issue - a bit of damage to the face, a door that's sticking slightly, a gap that's appeared at the bottom - it often means something else has shifted or failed. We've walked into conversions in Bow and Old Ford where someone's planed down a door to stop it dragging, not realising they've compromised the whole assembly in the process.

Bow's housing stock makes this worse. You've got post-war council blocks where the original doors are decades past their working life. Victorian terraces converted into flats where the door on your flat entrance was never a fire door to begin with. New builds near Bromley-by-Bow that look perfectly fine until you check the hardware properly.

What we do is look at the whole door - not just the obvious fault. We find what's actually failed, tell you what needs doing and why, then fix it to the standard it needs to meet.

Not what's quick. What's right.

Most people land on this page because a door's doing something it shouldn't - dragging on the frame, swinging back open, or sitting with a gap you could post a letter through. That's usually the starting point. But the repair that actually matters is often something you can't see: the intumescent strip.

Intumescent strips are the thing that saves lives. They sit in a routed channel along the door edge or frame, and under heat they expand to seal the gap and stop fire and gases spreading. We see them painted over in post-war council blocks across Bow constantly - whole strips buried under three decades of gloss paint, completely unable to expand. On older FD30 doors from the 1960s and 70s, they're often just missing entirely. That's not a minor defect. A fire door without a functioning intumescent strip isn't a fire door.

Most fire door repairs involve replacing damaged or missing intumescent strips and meeting stile seals at the same time - because cold smoke seals and intumescent strips work together, and there's no point doing one without the other.

In Victorian and Edwardian conversions - and there are plenty of them around Bow and Old Ford - we regularly find hollow-core doors that were never fire-rated to begin with, installed as flat entrance doors. That's a direct problem under the Fire Safety Order. Sometimes the door leaf itself can be repaired with hardwood lipping to bring gaps back within tolerance. Sometimes it can't, and we'll tell you that straight.

For timber fire doors with dropped hinges or a frame that's racked out of square, we use frame packing - non-combustible material fitted behind the lining to bring everything back into alignment before we address the gap. Excessive gap remediation done without fixing the underlying frame problem just fails again six months later. We've seen it.

Fire door gap issues on the threshold are their own category - often missed, always significant. A 10mm gap at the bottom of a flat entrance door in a converted terrace is a smoke leakage path. It needs threshold gap remediation, not a draught excluder from a hardware shop.

On the new-build side, particularly around Bromley-by-Bow, the doors themselves are usually fine - it's the ironmongery that lets them down. Non-CE-marked hinges, closers set too fast or too slow, missing cold smoke seals on the frame rebate. Incompatible hardware replacement is a straightforward job, but only if someone's actually checking for it.

If fire door repairs in Bow have come up off the back of a failed inspection, the defects list needs clearing in the right order - not just the ones that are easiest to fix first. Leave the intumescent strip until last and the door's been non-compliant the whole time you were working on it.

How We Handle Bow Fire Door Repairs

First thing we do is look at the door properly. Not a two-minute glance - an actual assessment of the leaf, the frame, the ironmongery, the gaps. Because what looks like a straightforward closer problem is often something else underneath. We've turned up to jobs where the customer thought they just needed a new closer, and the intumescent strip had been painted over, the threshold gap was sitting at 12mm, and one of the hinges had pulled away from the frame. Fix just the closer and you've fixed nothing.

Intumescent strip replacement is the most common repair we carry out - and the most frequently botched. The strip has to be the right specification for the door, seated correctly in the groove, and the groove itself has to be in decent condition. If it's been painted over - and in older council blocks around Bow this is extremely common - the strip can't expand properly in a fire. It's essentially decorative at that point. We remove the old material, check the rebate, and fit the correct grade of strip along with a cold smoke seal where one's missing or damaged.

Gaps come next. A fire door gap issues aren't always what they seem - sometimes the door has dropped on a worn hinge, sometimes the frame has moved, sometimes someone's had the door edge trimmed without understanding the limits on how much you can take off before you compromise the core. We work out the cause before we pick a fix. That might mean dropped hinge and door realignment, frame packing to square things up, or hardwood lipping applied to the edge to bring the gap back within tolerance. Getting this wrong means you're paying for the same repair twice.

Where a door has taken impact damage - common on communal corridor doors in residential blocks, especially anything with high footfall - we'll assess whether the leaf can be repaired or whether you're looking at a replacement. A cracked or delaminated face on an FD30 door isn't cosmetic. It's a structural failure of the fire-resistant assembly.

Once the remedial repair work is done, we photograph everything - before and after. If the job was flagged through an inspection report, we document the close-out against each defect line. That matters if you've got a managing agent, a fire door survey report, or a compliance requirement to satisfy.

A fire door repairs in Bow job that's done properly takes longer than a quick patch. But a quick patch on a fire door isn't a repair - it's a delay.
