Fire rated sealant in Poplar

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Fire rated sealant for homes and businesses in Poplar

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. We work on service penetrations, plasterboard & masonry and flats & HMOs, and common reasons people get in touch are sealant items on a fire risk assessment action list and open joints along the top of partitions.

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. Where a building in Poplar needs to stay open, work can be planned outside normal hours.

Our work is backed for twelve months.

What we do, step by step

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In Poplar, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Mention any parking rules near the property
  • Clear the area around the work

Advice

What we are called out for in Poplar

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

It’s worth asking for a quote if you see:

  • Unsealed gaps around fire door frames
  • New service routes left unsealed after building work
  • Gaps where walls meet ceilings or slabs
  • Gaps filled with a product that isn’t fire-rated

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

What your quote should include

  • What the quote includes, VAT included or not
  • What guarantee comes with the work
  • What happens if the job turns out different
  • Whether the sealant suits the joint

How to choose a mastic man

Fire rated sealant around Poplar

Poplar has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

If you let a flat or house near Canary Wharf station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Schools such as Tower Hamlets College are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

How the job changes by surface

Service penetrations

New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

Work for landlords, hotels and businesses

If you manage several properties in or around Poplar, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.

What affects the quote in Poplar

We don’t publish a price list, because jobs vary so much. What we look at:

  • Working hours on commercial sites
  • The old material and how stubborn it is
  • The number and length of the joints
  • Whether the work is at height

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Photos by email, if that’s easy
  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Check risers, ceiling voids and cupboards during building checks
  • File the fire-stopping record where your assessor can find it
  • Flag any open gap you spot round a pipe or cable
  • Make resealing part of every contractor’s brief

Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.

Your questions about fire rated sealant in Poplar

Can you help a landlord with a rental near Canary Wharf station?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.

Is parking an issue for fire rated sealant in Poplar?

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.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Can you fill the gap behind a fire door frame?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

How long does the job take?

Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer, and we’ll tell you how long to expect.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

Where do you work from?

We work from Crawley. We cover Poplar and the rest of Greater London, along with the rest of our area.

How much does fire rated sealant cost in Poplar?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
