About our fire rated sealant in Langstone
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We’re often asked to deal with unsealed gaps around fire door frames and unsealed gaps where pipes and cables go through a wall, on door frames, pipe & cable gaps and linear gaps.
Somewhere as small as Langstone, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Honest limits
It helps to know what we cannot do:
- Problems with the door itself rather than the gap around the frame

What the job involves on each surface
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.

Leave it or put it right?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Langstone, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What affects the cost of fire rated sealant
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The size of the job
- The type of sealant required
- How many rooms, windows or areas are involved
- Any mould that needs treating
What you pay reflects the work, not guesswork. That is why we ask about the job first.

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere like Langstone needs a little journey planning: let us know about lanes, gates and parking. 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.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.

Fire rated sealant in Langstone: local notes
For seaside hotels, guest houses and holiday lets around Langstone, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.
Managing a site like Bosmere Junior School? Then fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Havant station? Then any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Saint Nicholas' Chapel, gaps around pipes and cables are worth checking after any building work there.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Check risers, ceiling voids and cupboards during building checks
- Plan fire stopping into any work that goes through walls or floors
- Photograph sealed gaps before they’re covered up
- Tell trades working in the building that fire seals must be put back
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded so you can show it was dealt with.
