How it works
When we get to you, 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. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Cranford. A visitor permit or a nearby bay makes the visit run more smoothly.
- Before starting, we go through the specification or action list with you.
- 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.
Before we arrive
- Tell us about any water getting in
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can

Advice
Fire rated sealant in Cranford, done properly
Deciding which gaps need fire stopping isn’t our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for open gaps behind door architraves and holes left by a change of layout, on flats & HMOs, door frames and pipe & cable gaps.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Cranford can’t close.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Why act early in Cranford
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Cranford, the repair is bigger than a sealant job.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
When something else is needed
New sealant can’t fix everything, and we will tell you before any work starts. It won’t solve:
- Doors that are not fire doors in the first place
- Assessing a building’s fire safety
- Big openings where sealant alone is not the tested solution
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Commercial buildings in Cranford
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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
For landlords with property near Hayes & Harlington station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Cranford Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like The Parish Church of the Good Shepherd are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Cranford: your questions answered
Is parking a problem for a job in Cranford?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for landlords with property near Hayes & Harlington station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. We use whichever the specification and tested details call for.
How much does fire rated sealant cost in Cranford?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Where do you work from?
We work from Crawley. Our applicators cover Cranford.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Surface by surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each, and tell you if sealant alone is not the right fix.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Check risers, ceiling voids and cupboards during building checks
- Report cracked or damaged seals as soon as you notice them
- Photograph sealed gaps before they’re covered up
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
