Fire rated sealant in Round Bush
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. Typical jobs include gaps filled with a product that isn’t fire-rated and open holes round services passing through fire walls, on linear gaps, door frames and flats & HMOs.
Somewhere as small as Round Bush, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
There’s a 12-month guarantee on every job, whatever its size.

Why it’s worth doing now in Round Bush
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. Where a wall is exposed, as many are in small places like Round Bush, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What fire rated sealant looks like in Round Bush
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’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Fair Field Junior School, service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Radlett station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What affects the cost of fire rated sealant
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
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.

What we’re called out for in Round Bush
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
Common reasons people contact us are:
- Open joints along the top of partitions
- Fire seals that have cracked with movement
- Ordinary sealant used where a fire-rated product was needed
- New service routes left unsealed after building work
If you look after a church, hall or community building such as Church of St John the Baptist, older buildings that have had new heating or wiring often have service gaps worth checking.
What to look for in a quote
- The length of the guarantee
- Whether you can choose the colour
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared

What else we do in Round Bush
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Get damaged fire seals looked at promptly
- File the fire-stopping record where your assessor can find it
- Tell trades working in the building that fire seals must be put back
- Plan fire stopping into any work that goes through walls or floors
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Large holes that need a different fire-stopping system
- Assessing a building’s fire safety
- Fire doors that need new seals, closers or hardware
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
FAQs for Round Bush
Can you do fire rated sealant in Round Bush?
Yes. We work across London and the South East, and Round Bush is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Do you work for landlords with property near Radlett station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Do you certify the fire stopping?
That is not something we state or certify. Your specification sets the requirement, and we apply a product tested for it.
Will we have a record of what was sealed?
Yes. We record the locations we’ve sealed and the products used for your files.
