About our fire rated sealant in Swallows Cross
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We’re often asked to deal with seals cut through by electricians, plumbers or data installers and fire seals that have cracked with movement, on service penetrations, door frames and linear gaps.
If you have holiday lets, a converted barn used for business or a community building near Swallows Cross, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

When to call us in Swallows Cross
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
The problems people normally mention when they call include:
- Gaps around pipes and cables through fire-resisting walls
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Linear gaps at the head of walls
Letting a property close to Ingatestone station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Your questions about fire rated sealant in Swallows Cross
Will you come out to Swallows Cross?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Ingatestone station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you give us a record of the work?
Yes. Every gap we seal is listed with the product used.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Do you take on fire stopping in schools and offices?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we will plan the work to suit.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Swallows Cross and across Essex. We can quote a run of properties together.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. 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.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What affects the cost of fire rated sealant
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- Working hours on commercial sites
- Which sealant suits the joint
- The number and length of the joints
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

What else we do in Swallows Cross
What happens if it’s left?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. Where a wall is exposed, as many are in small places like Swallows Cross, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

What fire rated sealant looks like in Swallows Cross
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 Shenfield High School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
