About our fire rated sealant in Cranbrook
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We work on door frames, flats & HMOs and service penetrations, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and open gaps behind door architraves.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Where a building in Cranbrook needs to stay open, work can be planned outside normal hours.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Your questions about fire rated sealant in Cranbrook
Can parking be tricky for a visit in Cranbrook?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you take on hotel work around Cranbrook?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Keep children and pets away from the work area

Related advice
Signs you need fire rated sealant in Cranbrook
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.
These are the problems we’re asked about most:
- Damaged fire sealant left by other trades
- Old fire sealant that has split or come away
- Holes left by a change of layout
- Door frames with gaps between frame and wall
Cranbrook is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before booking
- Are they insured?
- How hidden problems are handled
- Whether the sealant suits the joint
- Who turns up on the day
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Take pictures of fire stopping before ceilings or boxing go back
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
- Store the list of sealed gaps with your building paperwork
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Doors that aren’t fire doors in the first place
- Construction that does not provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- Pipe & cable gaps
- Linear gaps
- Door frames
- Flats & HMOs
- Service penetrations

Workplaces and buildings in Cranbrook
Commercial buildings in London often have strict access rules and limited loading, 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.
For buildings such as St Clement's Church, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as The Ursuline Academy Ilford, gaps opened by contractors for new cabling are a common finding in schools and offices.
