Fire rated sealant in Brighton

How we handle fire rated sealant in Brighton

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We are often asked to deal with fire stopping disturbed by later work and open holes round services passing through fire walls, across linear gaps, door frames and plasterboard & masonry.

Brighton has offices, shops, places to stay and schools as well as homes, all with washrooms, kitchens and service openings that need the right sealant. Our work covers washroom and kitchen sealant as well as fire-rated sealant, fitted to the product’s tested details.

All our work is covered by our one-year guarantee.

Questions from Brighton

Do you cover Brighton for fire rated sealant?

Yes, Brighton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.

Do you take on hotel work around Brighton?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

I’m a tenant. Can you help?

We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame.

Which products do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Will there be a smell?

There can be a smell while the sealant cures. Opening a window helps.

Why it’s worth doing now in Brighton

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In flats, shops and offices in Brighton, a failed joint can let water into the unit below or behind a wall, where it can go unnoticed until the damage is done.

Rather than a set price list, 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

The quote reflects the job in front of us. We take into account:

  • How many rooms, windows or areas are involved
  • Any working-time requirements on site
  • Whether old sealant or filler has to be cut out
  • The number and length of the joints

Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • What’s wrong with the joints now
  • Any access issues, like height or stairs
  • Roughly how big the job is
  • Whether it has been sealed before

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.

DIY versus a professional finish

If you’ve already had a go yourself, that is fine. We cut it out and start again.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What we do, step by step

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. For homes and businesses in busier parts of Brighton, parking needs a little planning. For flats, mention stairs, lifts and shared entrances as well.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in
  • Mention if the joints have been sealed before

Advice

How the job changes by surface

Service penetrations

New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first.

When something else is needed

It helps to know what we can’t do:

  • Assessing a building’s fire safety
  • Big openings where sealant alone is not the tested solution
  • Sign-off of the building, which sits with building control or your assessor

Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Workplaces and buildings in Brighton

If you run a hotel, guest house or holiday let in a coastal place like Brighton, 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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Schools such as Fairlight Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as St Martin's Church, gaps around pipes and cables are worth checking after any building work there. For landlords with property near London Road (Brighton) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Check whether a sealant can be painted before decorating over it
  • Make resealing part of every contractor’s brief
  • Photograph sealed gaps before they’re covered up
  • Keep general-purpose foam and caulk away from fire-stopping gaps

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.
