Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Fire rated sealant around Butler's Cross
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’re given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Peter and St Paul, service openings in its walls need the right fire-rated sealant, as in any building. If you let a flat or house near Little Kimble station, any gap left by new services in shared walls should be closed with a fire-rated product.

- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.

Why deal with it now?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. Around Butler's Cross, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Openings too large for sealant, which need batts, boards or another system
- Assessing a building’s fire safety
- Walls or floors that weren’t built to resist fire
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Flats & HMOs
- Linear gaps

Butler's Cross: your questions answered
Do you work for landlords with property near Little Kimble station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Butler's Cross?
Yes. Butler's Cross is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you give us a record of the work?
Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.
Can you match the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What does intumescent mean?
Intumescent means it swells when heated to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Store the list of sealed gaps with your building paperwork
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Photograph sealed gaps before they’re covered up
- Include hidden areas like risers in routine checks
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.
Do you need fire rated sealant in Butler's Cross?
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 they leave doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Gaps left after a refit or conversion
- Old fire sealant that has split or come away
- Damaged fire sealant left by other trades
- Ordinary sealant used where a fire-rated product was needed
Schools such as John Colet School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
Before booking anyone
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Whether the sealant suits the joint
