What steel beam replacement & repair involves in Poole
We carry out steel beam replacement & repair in Poole, covering the BH12, BH13, BH14, BH15 and BH17 postcode districts. Our coverage runs across Dorset, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
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.
Key points for your project
- Many problem beams are not faulty steel at all but poor bearings. Ends resting on loose brick, timber offcuts or no padstone can crush the masonry beneath, and the beam then drops slightly and cracks the finishes above.
- 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.
- Older beams were often left with no fire protection or boxed in ordinary materials. When a beam is repaired or replaced, the fire protection is brought up to what the engineer and building control specify, commonly fire-rated plasterboard or intumescent paint.
- Beams fitted without calculations, whether decades ago or more recently without approval, may be smaller than the loads require, particularly in shop conversions and older knock-throughs. An engineer can check the existing section against the actual loads and say whether it is adequate.
- 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.
How the job runs in Poole
Free visit
A short visit to Poole 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 the local council's building control team, 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 Poole
For Poole, building control is provided by the local council's building control team, 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.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Steel beam replacement & repair in Poole: your questions
How much does steel beam replacement & repair cost in Poole?
As a guide, budget £2,050–£5,650 including VAT for steel beam replacement in Poole, 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 work on older or listed homes in Poole?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
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.
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.
How long does it take to replace a steel beam?
Anything from a day or two to around a week on site, depending on what the engineer specifies. Rebuilding a crushed bearing can be quick, while cutting out an old beam and fitting a new one in a typical room takes longer. Plastering and redecoration follow once building control has inspected the new steel.
