Fire rated sealant in Cheriton
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, so we work to the manufacturer’s details. Typical jobs include unsealed gaps around fire door frames and standard silicone or caulk in a fire-stopping gap, across linear gaps, service penetrations and door frames.
If you have holiday lets, a converted barn used for business or a community building near Cheriton, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

How the job changes by surface
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.

Cheriton: your questions answered
Do you cover Cheriton for fire rated sealant?
Yes. We work across London and the South East, and Cheriton is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Is fire rated sealant in Cheriton guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you tell me which gaps need fire stopping?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you do fire sealant around door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
Leave it or put it right?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. In a small place like Cheriton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask every contractor to reseal any fire stopping they disturb
- Flag any open gap you spot round a pipe or cable
- Keep the record of products and locations with your fire safety documents
Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Fire rated sealant around Cheriton
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.
Managing a site like Cheriton Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Honest limits
A few problems are outside what sealant work can do:
- Certifying a building or signing off its fire safety
- Deciding what fire stopping a building needs
- Openings too large for sealant, which need batts, boards or another system

What we’re called out for in Cheriton
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
The most common problems we see are:
- Standard silicone or caulk in a fire-stopping gap
- Seals cut through by electricians, plumbers or data installers
- Open joints along the top of partitions
- Fire seals that have cracked with movement
For buildings such as Church of St Michael, older buildings that have had new heating or wiring often have service gaps worth checking.
Questions to ask before you book
- Who turns up on the day
- What insurance they hold
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
