What fire protection for steel beams involves in Mitcham
Our fire protection for steel beams service in Mitcham covers everything from the first visit to the completion paperwork. Our coverage runs across London, so nearby villages are included too. Postcode districts we cover here include CR4, SM1, SM4, SM5 and SW16.
A bare steel beam is strong at room temperature but loses much of its load-carrying capacity once it gets hot enough in a fire. If that beam holds up a floor or the walls above, it matters to everyone in the building. Fire protection slows the rate at which the steel heats up, buying time for people to get out safely.
What to expect
- Building control treats fire protection as part of the structural approval, not an optional extra. If unprotected steel is found at inspection, the completion certificate is normally held back until the protection is in place and has been checked.
- Steel does not burn, but it loses stiffness and strength as it heats. Protection is there to keep the temperature of the beam down for a set period, so the floor or walls it carries stay up while people leave.
- Fire boarding should not be cut into casually later on. Downlights, cables and pipes pushed through the boxing can weaken it, so services are planned before boarding, and any openings are sealed with suitable fire-stopping materials.
- Damaged boxing or chipped intumescent paint should be repaired properly, not patched with ordinary filler. Small chips in a coating can usually be touched up with the same system, while a dented or holed box may need that board section replaced.
- Keep a record of what was fitted: the board type and number of layers, or the coating product, thickness readings and number of coats. Building control may ask for it, and it helps answer queries when the house is sold.
From survey to sign-off in Mitcham
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
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.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for Mitcham
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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.

Fire protection for steel beams in Mitcham: your questions
Do you also work near Mitcham?
Yes. We also cover nearby towns including Morden, Wimbledon, Streatham and Carshalton.
Can I stay at home while the work is done in Mitcham?
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 thick does intumescent paint need to be on a steel beam?
There is no single figure. The thickness depends on the steel section, how many sides are exposed and the fire period required, and the coating manufacturer's data sets the dry film thickness for each case. The applied thickness is measured with a gauge once the coats have dried and recorded for building control.
Does a steel column need fire protection as well as the beam?
Usually, if the column is part of the load path. A column carrying a beam is just as important in a fire, so it normally needs the same fire resistance. Columns are often boxed with board or coated with intumescent paint, and the engineer's design and building control confirm what applies to yours.
Does a steel beam in a house need fire protection?
Usually, yes. Where a steel beam or column holds up part of the structure, building regulations normally require it to resist fire for a set period, commonly 30 minutes in a typical house. Building control confirms what is needed for your property, and the protection is checked before the work is signed off.
Can you work on older or listed homes in Mitcham?
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.
