About our fire rated sealant in Selsdon
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. Typical jobs include gaps flagged on a fire risk assessment and open joints along the top of partitions, on door frames, linear gaps and plasterboard & masonry. Some people call us the mastic man, others the silicone man or the sealant specialist; in Selsdon, the job is the same: old material out, joints prepared and the right product used.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Selsdon, and room-by-room programmes can be planned where needed.
You get a one-year guarantee, the same in Selsdon as everywhere else we work.

Your questions about fire rated sealant in Selsdon
Is Selsdon in your area for fire rated sealant?
Yes, Selsdon is within the area we cover. Our work covers London and the South East. Just call 07833 053749 or send us an email with a few details of the job, and we’ll send you a clear quote.
Is parking a problem for a job in Selsdon?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is standard sealant good enough for a fire gap?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed.
Do you do fire sealant around door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door leaf and its hardware need a door specialist.
What fire rating will the seal have?
Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the amount of work. In Selsdon, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

Advice
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Aftercare tips
After the cure time, these simple habits help:
- Check risers, ceiling voids and cupboards during building checks
- Get damaged fire seals looked at promptly
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Take photos of fire stopping before ceilings or boxing go back
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Leave it or put it right?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Selsdon, the repair is bigger than a sealant job.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Workplaces and buildings in Selsdon
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.
If you look after a building such as Selsdon Primary and Nursery School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as St Francis, older buildings that have had new heating or wiring often have service gaps worth checking.
