Trusted fire rated sealant in Cripp's Corner

How it works

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Cripp's Corner needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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. Unsuitable material such as ordinary foam or silicone is cut out.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Mention any leaks or damp you’ve noticed
  • Mention any sign-in or site rules at work premises

What fire rated sealant looks like in Cripp's Corner

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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

Community buildings like St Marks Staplecross are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Robertsbridge station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Honest limits

A few problems are outside what sealant work can do:

  • Deciding what fire stopping a building needs
  • A wall that is not a fire-resisting element to begin with
  • Large holes that need a different fire-stopping system

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

Surfaces we seal

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

Different surfaces, different methods

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

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 record where they are.

Signs you need fire rated sealant in Cripp's Corner

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Common reasons people contact us include:

  • Unsealed gaps where pipes and cables go through a wall
  • Open joints along the top of partitions
  • Gaps left after a refit or conversion
  • Door frames with gaps between frame and wall

For site and facilities teams at buildings such as Staplecross Methodist Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Questions from Cripp's Corner

What does fire rated sealant cost?

Will you leave a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Is the work guaranteed?

Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.

What’s the difference between intumescent and fire-rated sealant?

An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.

Do you remove the old sealant?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

How long does fire rated sealant take?

That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.
