About our fire protection for steel beams service in Salisbury
Need fire protection for steel beams in Salisbury? The wider Wiltshire area is covered as well. We survey the property, arrange the engineer's design, deal with Wiltshire Council, fit the steel and make good, all under one quote for SP1 and SP2 addresses.
We fit fire protection alongside new steelwork, and as a standalone job where steel was installed without it or building control has asked for more. That covers boxing with fire-rated plasterboard, intumescent coatings for steel left on show, and the records building control needs to see before signing the work off.
Worth knowing before you start
- 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.
- Older homes sometimes have steel fitted decades ago with no protection at all, or boxed in ordinary timber and hardboard. When this turns up during other work, we can check what is there and price protection to suit today's requirements.
- 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.
- Intumescent paint looks like an ordinary coating but swells into a thick insulating char when heated. How well it performs depends on the dry film thickness, which varies with the steel section and fire period, so it is applied to a written specification.
- 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.
How the job runs in Salisbury
Free visit
A short visit to Salisbury to see the job, agree what you want and check the bearings, floors and services that affect the design.

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 Wiltshire 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 rules for Salisbury
Structural openings in English homes need building regulations approval before work starts. Wiltshire Council 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.

Local questions answered
Do I need a party wall agreement for fire protection for steel beams in Salisbury?
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.
Do you also work near Salisbury?
Yes. We also cover nearby towns including Andover, Totton, Southampton and Eastleigh.
My steel beam was fitted years ago without fire protection. What should I do?
Have it looked at and protected to current requirements. Unprotected steel can raise questions when you sell, and if the original work was never approved, a regularisation application to building control may be needed in England and Wales. We can survey the steel and price both the protection and the paperwork route.
Can I box in a steel beam with normal plasterboard?
Not where fire protection is required. Standard plasterboard is not designed to protect steel for a set period in a fire. Fire-rated plasterboard is used instead, fixed in the number of layers and with the fixings the system specifies, so the boxing performs as intended and passes when building control checks it.
What is intumescent paint for steel beams?
Intumescent paint is a fire-protective coating that swells when heated, forming a thick insulating layer that slows the steel heating up. It lets you leave a beam on show while still meeting fire requirements. It must be applied at a specified thickness over a compatible primer, so it goes on to a written specification rather than like ordinary paint.
Can you work on older or listed homes in Salisbury?
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.
