Fire rated sealant in Lydd-on-Sea
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. We work on service penetrations, linear gaps and pipe & cable gaps, and the jobs we see most are gaps flagged on a fire risk assessment and gaps around pipes and cables through fire-resisting walls.
For holiday lets, converted business premises or a community building near Lydd-on-Sea, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Big or small, you get the same one-year guarantee in Lydd-on-Sea and across Kent.

When to call us in Lydd-on-Sea
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
It’s worth asking for a quote if you see:
- Open joints along the top of partitions
- Gaps around pipes and cables through fire-resisting walls
- New service routes left unsealed after building work
- Open gaps behind door architraves
If you look after a building such as Greatstone Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before you book
- Whether all the old sealant comes out first
- What guarantee comes with the work
- Who turns up on the day
- What preparation is included
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Fire rated sealant around Lydd-on-Sea
If you run a hotel, guest house or holiday let in a coastal place like Lydd-on-Sea, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like St Peter's are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

FAQs for Lydd-on-Sea
Will you come out to Lydd-on-Sea?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do fire rated sealant in Lydd-on-Sea?
Yes, Lydd-on-Sea is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you take on fire stopping in schools and offices?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged if that suits the building.
Are you insured?
Yes, we’re fully insured for every job we do.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Openings too large for sealant, which need batts, boards or another system
- Problems with the door itself rather than the gap around the frame
- Construction that doesn’t provide fire resistance on its own
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

What affects the quote in Lydd-on-Sea
Every job gets its own quote. These are the things that affect it:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The number of rooms or windows
- Any mould that needs treating
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Where the property is
- Any access issues, like height or stairs
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or email us and describe the job, and photos are welcome.
Looking after it afterwards
To keep the joints looking good and working properly:
- Plan fire stopping into any work that goes through walls or floors
- Flag any open gap you spot round a pipe or cable
- Look in service cupboards and ceiling voids from time to time
- Ask which product was used before you paint
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.

What happens if it’s left?
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a small place like Lydd-on-Sea, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
