Fire rated sealant in Blackgang, done properly
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on flats & HMOs, service penetrations and pipe & cable gaps, and people most often call us about damaged fire sealant left by other trades and linear gaps at the head of walls.
For a small place like Blackgang, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Take photos of fire stopping before ceilings or boxing go back
- Look in service cupboards and ceiling voids from time to time
- Get damaged fire seals looked at promptly
- Store the list of sealed gaps with your building paperwork
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Blackgang, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

What sealant work can’t fix
In fairness, some problems need a different trade:
- Fire risk assessments, which need a qualified assessor
- Certifying a building or signing off its fire safety
- Doors that aren’t fire doors in the first place
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Door frames
- Flats & HMOs
- Service penetrations
- Plasterboard & masonry
- Linear gaps
- Pipe & cable gaps
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
When to call us in Blackgang
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
The problems people usually mention when they call are:
- Gaps left after a refit or conversion
- Unsealed gaps where pipes and cables go through a wall
- Cracked or shrunken fire-rated sealant
- Joints picked up in a fire-stopping survey
Schools such as Niton Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before you book
- When the joint can take water or movement
- The length of the guarantee
- Is the old sealant removed completely?
- What preparation is included
Commercial buildings in Blackgang
For seaside hotels, guest houses and holiday lets around Blackgang, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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 look after a church, hall or community building such as St Andrew's Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Yes, Blackgang is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
What guarantee comes with fire rated sealant in Blackgang?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
What does intumescent mean?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What do you need from me for a quote?
Let us know what needs doing and where, plus pictures if you have them. If we need more, we will ask.
Will we have a record of what was sealed?
Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like Blackgang, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.
