How we quote for fire rated sealant

For a quick quote, just ask. The main things that affect it are:

  • Whether old sealant or filler has to be cut out
  • When we can work, for business premises
  • Which sealant suits the joint
  • The size of the job

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

What to tell us for a quote

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

  • If it’s domestic, commercial or a hotel
  • The address or postcode of the job
  • Pictures of the joints, sent by email
  • How we’d reach the joints

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.

How we handle fire rated sealant in London Fields

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We are often asked to deal with old fire sealant that has split or come away and gaps flagged on a fire risk assessment, on door frames, pipe & cable gaps and linear gaps.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in London Fields cannot close.

Every job comes with our one-year guarantee.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • File the fire-stopping record where your assessor can find it
  • Check whether a sealant can be painted before decorating over it
  • Report cracked or damaged seals as soon as you notice them

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.

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

Work for landlords, hotels and businesses

We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured for the work.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

Fire rated sealant around London Fields

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

For landlords with property near London Fields station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Church of St Michael and All Angels, gaps around pipes and cables are worth checking after any building work there.

How the visit works

You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are 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. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • For business premises, tell us about site rules or sign-in
  • Mention any leaks or damp you’ve noticed

Do you need fire rated sealant in London Fields?

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps left after a refit or conversion
  • Fire stopping disturbed by later work
  • Sealant items on a fire risk assessment action list
  • Gaps around pipes and cables through fire-resisting walls

London Fields is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Before booking anyone

  • What happens if the job turns out different
  • How long to leave it before use
  • Is the old sealant removed completely?
  • The length of the guarantee

Choosing a sealant specialist

What happens if it’s left?

Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a flat in London Fields, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why book with us

  • Fully insured
  • Over 20 years’ experience
  • Trusted Arbo and Everbuild sealants
  • Anti-fungal sanitary silicone in wet areas

See our cost guide or what customers say.

Different surfaces, different methods

Flats and HMOs

Conversions generally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.

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.

FAQs for London Fields

Do you work for landlords with property near London Fields station?

Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Is parking a problem for a job in London Fields?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Are you fully insured?

Yes. Full insurance covers our work.

Is intumescent sealant the same as fire-rated sealant?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

Do you take on fire stopping in schools and offices?

Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Out-of-hours work can be arranged if that suits the building.

Is standard sealant good enough for a fire gap?

No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures.

Is it messy?

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