Steel beam replacement & repair in Falmouth: how it works
For homes in Falmouth and the TR10 and TR11 districts, we handle steel beam replacement & repair from survey to sign-off. We also cover the surrounding towns and villages in Cornwall. The beam is sized by a structural engineer and inspected before it is boxed in.
Not every steel beam was put in properly. Some were fitted decades ago without calculations, some sit on crumbling brick or timber packing, and some have rusted where water reached them through a leaking roof, a shopfront or a damp wall. Cracks in the plaster above, doors that stick or a visible dip are common warning signs.
What to expect
- Signs that a beam is struggling include diagonal cracks running up from its ends, a visible dip along its length, doors above that start binding, and rust staining through paint or plaster. Any one of these is worth an engineer's look.
- A repair only lasts if the cause is dealt with too. A leaking roof, blocked gutter or bridged damp-proof course that rusted the beam needs fixing first, otherwise new protective coatings will break down in the same way.
- Whether to strengthen or replace is the engineer's decision. Plating, where steel plates are fixed to the flanges, can add capacity without removing the beam, but it is not suitable for every section, connection or level of damage.
- Shop beams over old shopfronts are a common repair job. They often carry the whole front wall of the upper floors, sit behind fascias where rain gets in, and may have been cut or altered when shopfronts were replaced in the past.
- Like-for-like repainting needs no approval, but strengthening, rebuilding bearings or replacing a beam is structural work that falls under building control. Where an earlier beam went in without approval, a regularisation application in England and Wales can be used to seek retrospective sign-off.
From survey to sign-off in Falmouth
Free visit
A short visit to Falmouth to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to Cornwall Council, so approval is in place before the wall is touched.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Falmouth
For Falmouth, building control is provided by Cornwall Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Steel beam replacement & repair in Falmouth: your questions
Can I stay at home while the work is done in Falmouth?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
How much does steel beam replacement & repair cost in Falmouth?
As a guide, budget £2,050–£5,650 including VAT for steel beam replacement in Falmouth, based on published UK cost guides adjusted for prices in the South West (+3%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Can you replace a steel beam without taking the ceiling down?
Usually only part of the ceiling needs to come down. The boxing and a strip of ceiling either side of the beam are removed so props can go in and the old steel can come out. The rest of the room is protected, and the disturbed area is replastered to blend with the existing finish.
What does it mean to plate a steel beam?
Plating means fixing extra steel plates to the beam, usually along the flanges, to increase its strength or stiffness without taking it out. The plates are bolted or welded according to the engineer's design. It suits some beams well, but not all, and the engineer checks the connections and bearings before specifying it.
Why has my steel beam sagged?
A beam usually sags because it is too small for the load, the load has increased since it was fitted, or its bearings have crushed or moved. Every beam bends slightly within design limits, but a visible dip or new cracking suggests something has changed. An engineer can measure it and identify the cause.
Do I need a party wall agreement for steel beam replacement & repair in Falmouth?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
