About our fire rated sealant in Tooting Bec

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. Common call-outs are for damaged fire sealant left by other trades and open holes round services passing through fire walls, across flats & HMOs, linear gaps and plasterboard & masonry.

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 Tooting Bec can’t close.

Big or small, it’s backed by our 12-month guarantee in Tooting Bec and across Greater London.

Questions from Tooting Bec

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

Yes, landlords and agents are among the people we work for. 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.

Can parking be tricky for a visit in Tooting Bec?

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.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Is the work guaranteed?

Yes. Each job is guaranteed for twelve months, large or small.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

Do you come to Tooting Bec?

Yes, we do. Our applicators work in Tooting Bec.

Where are you based?

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

What sealant do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What we can’t put right

New sealant can’t fix everything, and we will tell you before any work starts. It won’t solve:

  • A wall that isn’t a fire-resisting element to begin with
  • Sign-off of the building, which sits with building control or your assessor
  • Big openings where sealant alone isn’t the tested solution

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Joints and surfaces we work on

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

How to look after the new joints

A little care helps the new joints last. Our advice:

  • Include fire stopping when you schedule refits
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • File the fire-stopping record where your assessor can find it
  • Keep pictures of seals that will be hidden

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.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

Fire rated sealant around Tooting Bec

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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

Managing a site like St Boniface RC Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Tooting Bec is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as St Augustine, gaps around pipes and cables are worth checking after any building work there.

What the job involves on each surface

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail and we’ll flag it.

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and the locations noted.

What affects the quote in Tooting Bec

We don’t publish a price list, because no two jobs are the same. The quote depends on:

  • Access and height
  • The size of the job
  • Whether there’s mould to deal with
  • How many areas need sealing

What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Asking for a quote

When you call or email, these details help:

  • Whether it’s a home or a business
  • Where the job is, and your postcode
  • How many joints, rooms or windows are involved
  • How we’d reach the joints

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes a few hours for a handful of gaps, and longer for a whole building. In Tooting Bec, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  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. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • Tell us about any previous sealing or DIY attempts
  • Clear the area around the work
