About our fire rated sealant in Bassett

Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for gaps around pipes and cables through fire-resisting walls and gaps flagged on a fire risk assessment, on pipe & cable gaps, plasterboard & masonry and flats & HMOs.

Around a place like Bassett, 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.

You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Plan fire stopping into any work that goes through walls or floors
  • Ask which product was used before you paint
  • Check risers, ceiling voids and cupboards during building checks
  • Ask every contractor to reseal any fire stopping they disturb

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded so the item can be closed.

How we quote for fire rated sealant

Call for a quick quote. What matters most is:

  • How easy the joints are to reach
  • The number of rooms or windows
  • Any mould that needs treating
  • The size of the job

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

What we need to know

There’s no need for technical detail. Just tell us:

  • If someone has resealed it before
  • Access, such as stairs, a lift or height
  • A few pictures by email, if you can
  • What’s wrong with the joints now

Getting a quote is simple: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

Why deal with it now?

Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a smaller place like Bassett, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Bassett: your questions answered

Do you cover Bassett for fire rated sealant?

Yes, Bassett is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.

I let a flat near Swaythling station. Can you help?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Will it make a mess?

No. The area is protected while we work and cleaned up afterwards.

Is there any odour?

Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

Do you certify the fire stopping?

That isn’t something we state or certify. Your specification sets the requirement, and we apply a product tested for it, recording the locations and products.

Where are you based?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Is standard sealant good enough for a fire gap?

No. A gap that needs fire stopping needs a tested fire-rated product.

Can I do it myself?

It depends on the job. 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.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Issuing a fire rating or certificate for a building
  • Assessing a building’s fire safety
  • Fire doors that need new seals, closers or hardware

If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Surfaces we seal

  • Plasterboard & masonry
  • Door frames
  • Pipe & cable gaps
  • Flats & HMOs
  • Linear gaps
  • Service penetrations

What the job involves on each surface

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before the sealant goes in.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.

What fire rated sealant looks like in Bassett

For seaside hotels, guest houses and holiday lets around Bassett, 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 work to the specification you’re given, installing the product to its tested details.

For landlords with property near Swaythling station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like St Michael and All Angels Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Cantell School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

How it works

Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Bassett, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

Getting ready for the visit

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
