Fire rated sealant in St Helens
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. Common call-outs are for cracked or shrunken fire-rated sealant and seals cut through by electricians, plumbers or data installers, on service penetrations, linear gaps and plasterboard & masonry.
For a small place like St Helens, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When to call us in St Helens
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
Signs it’s time to call us include:
- Fire seals that have cracked with movement
- Gaps where walls meet ceilings or slabs
- Seals cut through by electricians, plumbers or data installers
- Gaps around pipes and cables through fire-resisting walls
For buildings such as St Catherine-by-the-Green, older buildings that have had new heating or wiring often have service gaps worth checking.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. In a small place like St Helens, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on
- Mention any parking rules near the property
How to get a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

What else we do in St Helens
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in St Helens
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like St Helens, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Don’t paint over fire sealant until it has cured
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Allow for resealing whenever new services are run
- Get damaged fire seals looked at promptly
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
Commercial buildings in St Helens
For seaside hotels, guest houses and holiday lets around St Helens, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Brading station, any gap left by new services in shared walls should be closed with a fire-rated product. Managing a site like St Helens Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Questions from St Helens
Can you do fire rated sealant in St Helens?
Yes, St Helens is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Will you come out to St Helens?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Do you certify the fire stopping?
That is not something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
