Fire rated sealant in New Milton: local notes
If you run a hotel, guest house or holiday let in a coastal place like New Milton, 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. 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 work to the specification you’re given, installing the product to its tested details.
If you look after a church, hall or community building such as Parish Church of St Magdalene, gaps around pipes and cables are worth checking after any building work there. For landlords with property near New Milton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

About our fire rated sealant in New Milton
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on door frames, pipe & cable gaps and plasterboard & masonry, and people most often call us about fire seals that have cracked with movement and standard silicone or caulk in a fire-stopping gap.
In a smaller place like New Milton, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.
Big or small, it’s backed by our 12-month guarantee.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Take pictures of fire stopping before ceilings or boxing go back
- Include fire stopping when you schedule refits
- Ask which product was used before you paint
- Look in service cupboards and ceiling voids from time to time
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.

Landlords, agents and businesses in New Milton
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
What happens if it’s left?
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. Around New Milton, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear price for the lot.

Advice
What we are called out for in New Milton
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 isn’t a fire-rated seal.
These are the problems we are asked about most:
- Damaged fire sealant left by other trades
- Unsealed gaps around fire door frames
- Joints picked up in a fire-stopping survey
- New service routes left unsealed after building work
If you look after a building such as The Arnewood School, gaps opened by contractors for new cabling are a common finding in schools and offices.
What to look for in a quote
- Whether the sealant suits the joint
- How the colour is chosen
- What happens if the job turns out different
- When the joint can take water or movement
Different surfaces, different methods
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for the gap we’re sealing.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.
