Fire rated sealant in Chalkwell
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you have gaps where walls meet ceilings or slabs and open gaps behind door architraves, we can put it right.
Around a place like Chalkwell, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.
Big or small, it’s backed by our one-year guarantee in Chalkwell and across Southend-on-Sea.

Do you need fire rated sealant in Chalkwell?
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
The most common problems we see are:
- Open joints along the top of partitions
- Unsealed gaps around fire door frames
- Gaps left after a refit or conversion
- Gaps flagged on a fire risk assessment
If you look after a church, hall or community building such as St Michael and All Angels, gaps around pipes and cables are worth checking after any building work there.
What your quote should include
- Is the old sealant removed completely?
- Whether VAT is included
- When the joint can take water or movement
- The length of the guarantee
Keeping the joints in good condition
Aftercare is simple:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Tell trades working in the building that fire seals must be put back
- Get damaged fire seals looked at promptly
- File the fire-stopping record where your assessor can find it
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Surface by surface
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before work begins to keep disruption down.
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth with backing where the detail needs it.

What fire rated sealant looks like in Chalkwell
If you run a hotel, guest house or holiday let in a coastal place like Chalkwell, 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. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
Schools such as Chalkwell Hall Junior School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Chalkwell station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Assessing a building’s fire safety
- Problems with the door itself rather than the gap around the frame
- Openings too large for sealant, which need batts, boards or another system
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
Surfaces we seal
- Pipe & cable gaps

Why act early in Chalkwell
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own. Around Chalkwell, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Your questions about fire rated sealant in Chalkwell
Can you help a landlord with a rental near Chalkwell station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is Chalkwell within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
What we do, step by step
We keep the work tidy and contained to the area we’re working on. The job normally takes anything from a few hours to several days, depending on how many gaps there are. In a smaller place like Chalkwell, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
