About our fire rated sealant in Sellindge
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on plasterboard & masonry, door frames and pipe & cable gaps, and the jobs we see most are unsealed gaps where pipes and cables go through a wall and ordinary sealant used where a fire-rated product was needed.
If you have holiday lets, a converted barn used for business or a community building near Sellindge, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Our work is backed for twelve months.

Why it’s worth doing now in Sellindge
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Where a wall is exposed, as many are in small places like Sellindge, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. For a village or hamlet like Sellindge, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Advice
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Plan fire stopping into any work that goes through walls or floors
- Get damaged fire seals looked at promptly
- Do not paint over fire sealant until it has cured
- Never patch a fire seal with standard sealant
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
Common questions in Sellindge
Is Sellindge within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Sellindge in your area for fire rated sealant?
Yes, Sellindge is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Sellindge.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Landlord and commercial work in Sellindge
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
When to call us in Sellindge
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.
Keep an eye out for these signs:
- Linear gaps at the head of walls
- Damaged fire sealant left by other trades
- Gaps filled with a product that is not fire-rated
- Unsealed gaps around fire door frames
For landlords with property near Westenhanger station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

When it is not the sealant
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
- Openings too large for sealant, which need batts, boards or another system

Commercial buildings in Sellindge
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, 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.
Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Sellindge Primary School, fire-stopping around service openings should be restored whenever new services go in.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
