About our fire rated sealant in North Ockendon

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Typical jobs include gaps around pipes and cables through fire-resisting walls and gaps left after a refit or conversion, across pipe & cable gaps, flats & HMOs and plasterboard & masonry.

Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in North Ockendon, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.

Our work is backed for twelve months.

Do you need fire rated sealant in North Ockendon?

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

Signs it’s time to call us include:

  • Unsealed gaps where pipes and cables go through a wall
  • Holes left by a change of layout
  • Damaged fire sealant left by other trades
  • Old fire sealant that has split or come away

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

Our hiring checklist

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

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.

What we cannot put right

We will not take on work that won’t last, so here’s what sealant can’t put right:

  • Doors that are not fire doors in the first place
  • Fire risk assessments, which need a qualified assessor
  • Certifying a building or signing off its fire safety

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

What we seal

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

Looking after it afterwards

After the cure time, these simple habits help:

  • Photograph sealed gaps before they’re covered up
  • Ask which product was used before you paint
  • Plan fire stopping into any work that goes through walls or floors
  • Never patch a fire seal with standard sealant

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

For landlords and businesses

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

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

Workplaces and buildings in North Ockendon

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.

If you let a flat or house near Ockendon station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as The James Oglethorpe Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Surface by surface

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.

Flats and HMOs

Conversions usually leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and record where they are.

How it works

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. For a job in North Ockendon, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your files.

Before we arrive

  • Mention any tricky access
  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we’re working on
