Fire rated sealant across Essendon and nearby, with old sealant always removed completely and a one-year guarantee.
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
- Gaps flagged on a fire risk assessment
How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Essendon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
Fire rated sealant in Essendon, done properly
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Typical jobs include ordinary sealant used where a fire-rated product was needed and unsealed gaps around fire door frames, across linear gaps, pipe & cable gaps and plasterboard & masonry.
For a small place like Essendon, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
All of our work is guaranteed for twelve months, in Essendon and everywhere else we cover.

Different surfaces, different methods
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Your questions about fire rated sealant in Essendon
Will you come out to Essendon?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Bayford station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Can you give us a record of the work?
Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Will you assess my building’s fire safety?
No. We work from the specification you give us.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What affects the quote in Essendon
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- Which sealant suits the joint
- How much there is to do
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
When you call or email, these details help:
- Access, such as stairs, a lift or height

- The address or postcode of the job

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Include fire stopping when you schedule refits
- Tell trades working in the building that fire seals must be put back
- Store the list of sealed gaps with your building paperwork
- Do not fill fire-stopping gaps with ordinary foam or silicone
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What fire rated sealant looks like in Essendon
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.
Schools such as Essendon CofE (VC) Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of St Mary the Virgin are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Bayford station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Walls or floors that weren’t built to resist fire
- Issuing a fire rating or certificate for a building
- Deciding what fire stopping a building needs
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
