Fire rated sealant in Stansted, done properly

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. Common call-outs are for joints picked up in a fire-stopping survey and seals cut through by electricians, plumbers or data installers, on door frames, plasterboard & masonry and service penetrations.

For a small place like Stansted, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

Whatever the size of the job, you get the same 12-month guarantee in Stansted and across Kent.

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Plan fire stopping into any work that goes through walls or floors
  • Tell trades working in the building that fire seals must be put back
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Check whether a sealant can be painted before decorating over it

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

How the job changes by surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before the sealant goes in.

Flats and HMOs

Working in occupied flats needs some planning. We agree access to each flat and the common parts before any work starts to keep disruption down.

What fire rated sealant looks like in Stansted

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 look after a building such as Wrotham School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Leave it or put it right?

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. Around Stansted, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Stansted questions

Do you work for landlords with property near Borough Green & Wrotham station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Will you come out to Stansted?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can ordinary silicone be used in a fire-stopping gap?

No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Can you tell me how many minutes the seal will last?

Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.

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

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. We use whichever the specification and tested details call for.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and you’ll get one quote.

Can you work in occupied buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.

Common problems we fix in Stansted

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common.

Signs it’s time to call us include:

  • Gaps left after a refit or conversion
  • Open holes round services passing through fire walls
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps flagged on a fire risk assessment

If you let a flat or house near Borough Green & Wrotham station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What your quote should include

  • How long the guarantee is
  • What happens if they find a problem under the old sealant
  • How long to leave it before use
  • What product goes in the joint

Our hiring checklist

Can I do it myself?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. In a small place like Stansted, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

How to prepare

  • Mention if the joints have been sealed before
  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive
