Fire-rated sealant in Horton, Surrey
Fire rated sealant across Horton and nearby, with old sealant always removed completely and a one-year guarantee.
- Open gaps behind door architraves
- Sealant items on a fire risk assessment action list
- Cracked or shrunken fire-rated sealant
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
Fire rated sealant in Horton
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We are often asked to deal with cracked or shrunken fire-rated sealant and open holes round services passing through fire walls, on door frames, pipe & cable gaps and flats & HMOs.
In a village or hamlet like Horton, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Older cottages and farmhouses around Horton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear price before any work starts.

Questions from Horton
I let a flat near Chessington South station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Horton?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient.
Do you seal gaps around fire door frames?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- File the fire-stopping record where your assessor can find it
- Flag any open gap you spot round a pipe or cable
- Look in service cupboards and ceiling voids from time to time
- Make resealing part of every contractor’s brief
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
How it works
At the end, we look at the finished work together. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. For a village or hamlet like Horton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

Advice
Honest limits
It helps to know what we cannot do:
- Issuing a fire rating or certificate for a building
- Large holes that need a different fire-stopping system
- Construction that does not provide fire resistance on its own
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on
- Linear gaps
- Plasterboard & masonry
- Door frames
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
Different surfaces, different methods
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.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Commercial buildings in Horton
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Letting a property close to Chessington South station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Church of St Mary the Virgin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Do you need fire rated sealant in Horton?
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Look out for these signs:
- New service routes left unsealed after building work
- Damaged fire sealant left by other trades
- Open holes round services passing through fire walls
- Linear gaps at the head of walls
For site and facilities teams at buildings such as St Mary's CofE (Aided) Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
