Fire rated sealant in Gosport, done properly
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, gap by gap. We work on pipe & cable gaps, door frames and linear gaps, and common reasons people get in touch are damaged fire sealant left by other trades and open holes round services passing through fire walls.
For a small place like Gosport, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
Whatever the size of the job, it’s backed by our 12-month guarantee in Gosport and across Hampshire.

Landlord and commercial work in Gosport
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant won’t do:
- Big openings where sealant alone is not the tested solution
- Deciding what fire stopping a building needs
- Doors that aren’t fire doors in the first place
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Where we work in Gosport
- Door frames
- Service penetrations

Fire rated sealant in Gosport: 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, 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.
For site and facilities teams at buildings such as Ampfield Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in. For buildings such as Church of St Mark, gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Chandlers Ford station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What happens if it’s left?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Around Gosport, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Questions from Gosport
Do you cover smaller places like Gosport?
Yes, Gosport is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Gosport for fire rated sealant?
Yes, Gosport is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What does intumescent mean?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Surface by surface
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach and we’ll flag it.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. Somewhere like Gosport needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
How to prepare
- Keep children and pets away from the work area
- Mention any tricky access
