Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Plan fire stopping into any work that goes through walls or floors
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Take photos of fire stopping before ceilings or boxing go back
- Check risers, ceiling voids and cupboards during building checks
Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
Fire rated sealant for homes and businesses in Swanley
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. 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 plasterboard & masonry, service penetrations and linear gaps, and common reasons people get in touch are open joints along the top of partitions and old fire sealant that has split or come away.
If you run a pub, café, guest house or shop in or near Swanley, the washrooms and kitchen need the same attention as a big site.
You get a 12-month guarantee, the same in Swanley as everywhere else we work.

Workplaces and buildings in Swanley
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 work to the specification you are given, installing the product to its tested details.
For landlords with property near Swanley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like St Bartholomew's Catholic Primary School? Then fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as St Mary the Virgin, service openings in its walls need the right fire-rated sealant, as in any building.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Leave it or put it right?
For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we’ll tell you. In an older home around Swanley, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What does intumescent mean?
Intumescent means it swells when heated to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Do you certify the fire stopping?
We do not 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.

Yes. Mr Mastic is fully insured.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a job in Swanley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Keep children and pets away from the work area
How to get a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

Different surfaces, different methods
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

What sealant work cannot fix
A few problems are outside what sealant work can do:
- Walls or floors that weren’t built to resist fire
- Problems with the door itself rather than the gap around the frame
- Big openings where sealant alone is not the tested solution
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
