Different surfaces, different methods
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.
Fire rated sealant in West Mersea
We don’t assess buildings or decide what fire stopping is needed; 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. We work on service penetrations, plasterboard & masonry and flats & HMOs, and the jobs we see most are fire stopping disturbed by later work and gaps left after a refit or conversion.
For a pub, café, guest house or shop in or near West Mersea, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Questions from West Mersea
What guarantee comes with fire rated sealant in West Mersea?
All our work, in West Mersea and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like West Mersea?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is standard sealant good enough for a fire gap?
No. A gap that needs fire stopping needs a tested fire-rated product.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
How much does fire rated sealant cost in West Mersea?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Helping us quote
To make quoting easier, please include:
- The rough size of the job
- Photos by email, if that’s easy
- Any access issues, like height or stairs
- The address or postcode of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Common problems we fix in West Mersea
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common.
Keep an eye out for these signs:
- Door frames with gaps between frame and wall
- Holes left by a change of layout
- Gaps around pipes and cables through fire-resisting walls
- Joints picked up in a fire-stopping survey
Community buildings like Church of St Peter and St Paul are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
What your quote should include
- How hidden problems are handled
- Is VAT in the price?
- Whether the sealant suits the joint
- Whether they’re fully insured

What happens if it’s left?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. In a smaller place like West Mersea, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
How it works
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like West Mersea, 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.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Clear the area around the work
