About our fire rated sealant in Rosehill
We can work through a building room by room or floor by floor. That record is useful for your files and for whoever looks at the building next. If you have gaps where walls meet ceilings or slabs and fire seals that have cracked with movement, 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 Rosehill, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
All our work is covered by a one-year guarantee, wherever you are in Greater London.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Allow for resealing whenever new services are run
- Keep the record of products and locations with your fire safety documents
- Do not paint over fire sealant until it has cured
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we will tell you which one you have.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Deciding what fire stopping a building needs
- Problems with the door itself rather than the gap around the frame
- Construction that doesn’t provide fire resistance on its own
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

- Door frames
- Pipe & cable gaps
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Linear gaps
Why deal with it now?
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

I let a flat near Sutton Common station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover Rosehill for fire rated sealant?
Yes. Our work covers London and the South East, and Rosehill is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Do you do fire sealant around door frames?
Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.
Where do you work from?
We work from Crawley. We cover Rosehill and the rest of Greater London, along with the rest of our area.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
Can you tell me how many minutes the seal will last?
We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How the visit works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job generally takes anything from a few hours to several days, depending on how many gaps there are. In a London area like Rosehill, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Mention any parking rules near the property

Quotes for fire rated sealant in Rosehill
Every job gets its own quote. This is what makes a difference:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- How much there is to do
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- Whether it’s a home or a business
- The rough size of the job
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Signs you need fire rated sealant in Rosehill
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
It’s worth asking for a quote if you see:
- Fire stopping disturbed by later work
- Door frames with gaps between frame and wall
- Ordinary sealant used where a fire-rated product was needed
- Fire seals that have cracked with movement
For site and facilities teams at buildings such as Tweeddale Primary School, fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
- How much experience the applicator has
- What preparation is included
Workplaces and buildings in Rosehill
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Community buildings like St Peter's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For landlords with property near Sutton Common station, any gap left by new services in shared walls should be closed with a fire-rated product.
