Fire rated sealant near The Burroughs

Fire rated sealant in The Burroughs, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. Typical jobs include joints picked up in a fire-stopping survey and seals cut through by electricians, plumbers or data installers, across door frames, linear gaps and flats & HMOs.

In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in The Burroughs.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

How we quote for fire rated sealant

Your quote is based on your job. We take into account:

  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove
  • Whether there’s mould to deal with
  • Any working-time requirements on site

What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The rough size of the job
  • The problem you’ve noticed
  • A few pictures by email, if you can
  • Any previous sealing or DIY work

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

What fire rated sealant looks like in The Burroughs

The Burroughs has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.

If you let a flat or house near Hendon station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as St Joseph's Catholic Primary School, fire-stopping around service openings should be restored whenever new services go in.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

The Burroughs questions

Do you take on hotel work around The Burroughs?

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.

Is parking a problem for a job in The Burroughs?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

How much does fire rated sealant cost in The Burroughs?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Do you certify the fire stopping?

That is not something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint.

Can you tell me which gaps need fire stopping?

No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Can I use normal mastic around a pipe through a fire wall?

No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service.

Can you give us a record of the work?

Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

How it works

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on how many gaps there are from start to finish. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in The Burroughs. 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. We take out any damaged or unsuitable sealant.
  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.

How to prepare

  • Clear items away from the joints we’re working on
  • For business premises, tell us about site rules or sign-in
  • Keep children and pets away from the work area

When to call us in The Burroughs

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Look out for any of the following:

  • Seals cut through by electricians, plumbers or data installers
  • New service routes left unsealed after building work
  • Open gaps behind door architraves
  • Standard silicone or caulk in a fire-stopping gap

For buildings such as St Mary's Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Before booking anyone

  • Whether they’re fully insured
  • What happens if the job turns out different
  • What the quote includes, VAT included or not
  • Is the old sealant removed completely?

10 questions to ask before booking

How to look after the new joints

So the new joints stay in good condition:

  • Include hidden areas like risers in routine checks
  • Plan fire stopping into any work that goes through walls or floors
  • Ask every contractor to reseal any fire stopping they disturb
  • 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.

Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

What we can’t put right

New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant won’t put right:

  • Assessing a building’s fire safety
  • Certifying a building or signing off its fire safety
  • Walls or floors that weren’t built to resist fire

If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
