How we handle fire rated sealant in Blackbrook
We can work through a building room by room or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. If you have gaps where walls meet ceilings or slabs and unsealed gaps around fire door frames, we can help, on door frames, pipe & cable gaps and linear gaps alike.
If you have holiday lets, a converted barn used for business or a community building near Blackbrook, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You get a 12-month guarantee, the same in Blackbrook as everywhere else we work.

Questions from Blackbrook
Do you cover smaller places like Blackbrook?
Yes. Blackbrook is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Holmwood station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you do fire sealant around door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant, to the product’s details. The door leaf and its hardware need a door specialist.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Allow for resealing whenever new services are run
- Make resealing part of every contractor’s brief
- Do not paint over fire sealant until it has cured
- Keep the record of products and locations with your fire safety documents
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Common problems we fix in Blackbrook
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
Look out for these signs:
- Open joints along the top of partitions
- Ordinary sealant used where a fire-rated product was needed
- Door frames with gaps between frame and wall
- Seals cut through by electricians, plumbers or data installers
Schools such as St John's Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Blackbrook, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Certifying a building or signing off its fire safety
- A wall that is not a fire-resisting element to begin with
- 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.
Surfaces we seal
- Door frames
- Plasterboard & masonry
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
- Linear gaps
Why act early in Blackbrook
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a small place like Blackbrook, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost 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 we start, so you know where you stand.
Why book with us
- Over 20 years’ experience
- Any old sealant cut out fully, not covered over
- Homes, businesses and hotels
- Approved under the ARBOMaster scheme

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, 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
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before we start to keep disruption down.
Fire rated sealant in Blackbrook: local notes
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Holmwood station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Church of St John the Evangelist, older buildings that have had new heating or wiring often have service gaps worth checking.
