How we handle fire rated sealant in Cranham
We don’t assess buildings or decide what fire stopping is needed; 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. If you have fire seals that have cracked with movement and open joints along the top of partitions, we can put it right, whatever the surface.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Cranham, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
There’s a 12-month guarantee on every job, large or small.

Fire rated sealant in Cranham: local notes
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
As a London address, Cranham can be tricky for parking: let us know about parking bays, permits or a driveway. For landlords with property near Upminster station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Hall Mead School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

How to look after the new joints
Looking after new joints is easy:
- Store the list of sealed gaps with your building paperwork
- Take photos of fire stopping before ceilings or boxing go back
- Do not paint over fire sealant until it has cured
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.
The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a handful of gaps, and longer for a whole building from start to finish. For a job in Cranham, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- 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
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Related advice
Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.
When something else is needed
Before booking, it’s worth knowing the limits:
- Big openings where sealant alone isn’t the tested solution
- Doors that are not fire doors in the first place
- Assessing a building’s fire safety
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

FAQs for Cranham
Do you work for landlords with property near Upminster station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you cover Cranham for fire rated sealant?
Yes. We work across London and the South East, and Cranham is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Can ordinary silicone be used in a fire-stopping gap?
No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
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.
Will we have a record of what was sealed?
Yes. We record the locations we’ve sealed and the products used.
