How we handle fire rated sealant in Haultwick

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. Common call-outs are for sealant items on a fire risk assessment action list and cracked or shrunken fire-rated sealant, on flats & HMOs, plasterboard & masonry and pipe & cable gaps.

Somewhere as small as Haultwick, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

All our work comes with a 12-month guarantee, wherever you are in Hertfordshire.

When to call us in Haultwick

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.

The problems people generally mention when they call include:

  • Joints picked up in a fire-stopping survey
  • Gaps filled with a product that isn’t fire-rated
  • Fire stopping disturbed by later work
  • Holes left by a change of layout

If you look after a church, hall or community building such as Parish Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

What to look for in a quote

  • How the surfaces are prepared before sealing
  • Whether all the old sealant comes out first
  • What guarantee comes with the work
  • Whether they’re fully insured

10 questions to ask before you book

How to look after the new joints

So the new joints stay in good condition:

  • Never patch a fire seal with standard sealant
  • Flag any open gap you spot round a pipe or cable
  • Ask every contractor to reseal any fire stopping they disturb
  • Keep photos of seals that will be hidden

Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Haultwick needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Keep pets and children clear of the area while we work
  • Where the joints are inside, avoid wetting them before we arrive

How the job changes by surface

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail and we’ll flag it.

Flats and HMOs

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

How we quote for fire rated sealant

The price is agreed before any work begins. It takes into account:

  • Whether old sealant or filler has to be cut out
  • How easy the joints are to reach
  • When we can work, for business premises
  • The size of the job

What you pay reflects the work, not guesswork. That is why we ask about the job first.

What we need to know

To make quoting easier, please include:

  • Any access issues, like height or stairs
  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • Any previous sealing or DIY work

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.

What fire rated sealant looks like in Haultwick

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’re given, installing the product to its tested details.

Rented homes near Watton-At-Stone station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Munden Church of England Voluntary Controlled Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

  • Openings too large for sealant, which need batts, boards or another system
