Fire rated sealant in North End
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you have damaged fire sealant left by other trades and old fire sealant that has split or come away, we can put it right, whatever the surface.
Around a place like North End, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
FAQs for North End
I let a flat near Hilsea station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover North End for fire rated sealant?
Yes, North End is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- File the fire-stopping record where your assessor can find it
- Ask which product was used before you paint
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Check risers, ceiling voids and cupboards during building checks
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
What affects the quote in North End
Every job gets its own quote. This is what makes a difference:
- When we can work, for business premises
- Mould in or behind the old joints
- The number of rooms or windows
- Whether the work is at height
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or drop us an email.
Fire rated sealant in North End: local notes
For seaside hotels, guest houses and holiday lets around North End, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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, 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.
Letting a property close to Hilsea station? Then any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as St. Mark’s, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Corpus Christi Catholic Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
North End is about 1 mile north of Portsmouth, in Portsmouth. From the centre of North End to the outskirts, fire rated sealant is available for homes and businesses alike, from flats and houses to offices and hotels. North End is one of 19 towns and villages in Portsmouth we cover for fire rated sealant.

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. A visit to North End is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before

What the job involves on each surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Doors that aren’t fire doors in the first place
- A wall that is not a fire-resisting element to begin with
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
