Why deal with it now?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. Around Worlds End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Fire rated sealant in Worlds End
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. Typical jobs include open holes round services passing through fire walls and new service routes left unsealed after building work, across flats & HMOs, plasterboard & masonry and door frames.
For a small place like Worlds End, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
Each job carries a 12-month guarantee.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Check whether a sealant can be painted before decorating over it
- Store the list of sealed gaps with your building paperwork
- Tell trades working in the building that fire seals must be put back
- Allow for resealing whenever new services are run
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
What fire rated sealant looks like in Worlds End
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.
If you let a flat or house near Portchester station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Around Worlds End, as everywhere, fire rated sealant is only as good as the preparation behind it.

Questions from Worlds End
Do you cover smaller places like Worlds End?
Yes, Worlds End is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Do you seal gaps around fire door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
Is standard sealant good enough for a fire gap?
No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Are you insured?
Yes. Full insurance covers our work.

Surface by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall.
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.
