Fire rated sealant for Barking Riverside homes and businesses

What affects the cost of fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • The type of sealant required
  • The number of rooms or windows
  • How easy the joints are to reach
  • Any mould that needs treating

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 to tell us for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • Access, such as stairs, a lift or height
  • Whether it has been sealed before
  • A few photos by email, if you can
  • The problem you’ve noticed

Every job is quoted individually. Just call 0345 464 0079 or send us an email with the details.

Fire rated sealant in Barking Riverside, done properly

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. If you have sealant items on a fire risk assessment action list and gaps where walls meet ceilings or slabs, we can put it right, whatever the surface.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Where a building in Barking Riverside needs to stay open, work can be planned outside normal hours.

Our work is backed for twelve months.

Common questions in Barking Riverside

Do you cover Barking Riverside for fire rated sealant?

Yes, Barking Riverside is within the area we cover. We work across London and the South East. You can phone 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 Barking Riverside station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Do you guarantee your work?

Yes. There’s a 12-month guarantee on every job, large or small.

Which products do you use?

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

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

What does fire rated sealant cost?

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

What information do you need?

Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.

Aftercare tips

After the cure time, these simple habits help:

  • File the fire-stopping record where your assessor can find it
  • Flag any open gap you spot round a pipe or cable
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Photograph sealed gaps before they’re covered up

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.

Do you need fire rated sealant in Barking Riverside?

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

Look out for these signs:

  • Open holes round services passing through fire walls
  • Sealant items on a fire risk assessment action list
  • Cracked or shrunken fire-rated sealant
  • Open gaps behind door architraves

Barking Riverside is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Questions to ask before you book

  • How long to leave it before use
  • Whether they seal over old material or remove it
  • Is VAT in the price?
  • What happens if they find a problem under the old sealant

Choosing a sealant specialist

What the job involves on each surface

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.

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.

Can I do it myself?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What sealant work can’t fix

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Construction that does not provide fire resistance on its own
  • Assessing a building’s fire safety
  • Fire doors that need new seals, closers or hardware

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

Surfaces we seal

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

What we do, step by step

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

How to prepare

  • Clear items away from the joints we’re working on
  • Try not to wet indoor joints just before the visit
  • Mention any sign-in or site rules at work premises

Workplaces and buildings in Barking Riverside

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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.

Schools such as George Carey Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Christ Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
