Fire rated sealant for Tooting homes and businesses

What the job involves on each surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.

How we handle fire rated sealant in Tooting

We often work from an action list drawn up by a fire risk assessor for buildings in Tooting. If you share the list, we can quote for the gaps that need fire-rated sealant. If you have gaps around pipes and cables through fire-resisting walls and old fire sealant that has split or come away, we can help.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Tooting, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

All of our work is guaranteed for twelve months.

FAQs for Tooting

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

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.

Do you cover Tooting for fire rated sealant?

Yes. Our work covers London and the South East, and Tooting is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.

Is standard sealant good enough for a fire gap?

No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.

Can you tell me how many minutes the seal will last?

We don’t give ratings or certificates for our work. Your specification sets the requirement, and we fit a product whose tested details meet it, recording the locations and products.

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

What do you need from me for a quote?

A short description and the location. We’ll ask anything else we need to know.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame and we will tell you if we spot problems with the door.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.

Honest limits

To be straight with you, there are a few things sealant won’t fix:

  • Fire risk assessments, which need a qualified assessor
  • Openings too large for sealant, which need batts, boards or another system
  • Issuing a fire rating or certificate for a building

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

What fire rated sealant looks like in Tooting

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

As a London address, Tooting can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like St Boniface RC Primary School? Then fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Tooting station, any gap left by new services in shared walls should be closed with a fire-rated product.

What affects the cost of fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • Whether there’s mould to deal with
  • Working hours on commercial sites
  • How much there is to do
  • The number of rooms or windows

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

What we need to know

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

  • The address or postcode of the job
  • The type of property
  • Any previous sealing or DIY work
  • Any access issues, like height or stairs

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or send us an email.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Plan fire stopping into any work that goes through walls or floors
  • Do not paint over fire sealant until it has cured
  • Get damaged fire seals looked at promptly
  • Store the list of sealed gaps with your building paperwork

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What we do, step by step

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any parking rules near the property
  • Tell us about any previous sealing or DIY attempts

What happens if it’s left?

A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before we start.
