Questions from Chinbrook
I let a flat near Grove Park station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you do fire rated sealant in Chinbrook?
Yes. We work across London and the South East, and Chinbrook is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Are you insured?
Yes. We’re fully insured.
About our fire rated sealant in Chinbrook
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. We are often asked to deal with new service routes left unsealed after building work and cracked or shrunken fire-rated sealant, across plasterboard & masonry, door frames and flats & HMOs.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Chinbrook, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Our work is backed for twelve months.

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.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Do you need fire rated sealant in Chinbrook?
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
If you can see any of these, it’s time to have the joints looked at:
- Gaps around pipes and cables through fire-resisting walls
- Door frames with gaps between frame and wall
- Sealant items on a fire risk assessment action list
- Seals cut through by electricians, plumbers or data installers
Chinbrook is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
What to look for in a quote
- Whether the sealant suits the joint
- Whether they’re fully insured
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
Looking after it afterwards
So the new joints stay in good condition:
- Never patch a fire seal with standard sealant
- Look in service cupboards and ceiling voids from time to time
- Include fire stopping when you schedule refits
- Get damaged fire seals looked at promptly
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we’ll tell you which one you have.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
What we can’t put right
We will always be straight with you, so here’s what sealant cannot fix:
- A wall that isn’t a fire-resisting element to begin with
- Big openings where sealant alone isn’t the tested solution
- Certifying a building or signing off its fire safety
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Fire rated sealant around Chinbrook
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.
For buildings such as Jubilee International Church, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Marvels Lane Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What you get with us
- Homes, businesses and hotels
- Trusted Arbo and Everbuild sealants
- Anti-fungal silicone where joints get wet
