Trusted fire rated sealant in East End

Fire rated sealant for homes and businesses in East End

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through. If you have old fire sealant that has split or come away and open joints along the top of partitions, we can put it right, on linear gaps, plasterboard & masonry and pipe & cable gaps alike.

If you have holiday lets, a converted barn used for business or a community building near East End, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

The process

We keep the work tidy and contained to the joints we are treating. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. Somewhere as small as East End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed.
  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 records.

How to prepare

  • Let us know about earlier repairs to the joints
  • Keep pets and children clear of the area while we work
  • On commercial sites, let us know about site rules

Leave it or put it right?

A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Around East End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.

Quotes for fire rated sealant in East End

Jobs vary more than people expect. What affects the quote:

  • The product the joint needs
  • The size of the job
  • Any working-time requirements on site
  • Whether the work is at height

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

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

  • Any previous sealing or DIY work
  • A few photos by email, if you can
  • Where the property is
  • Any access issues, like height or stairs

Honest limits

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Walls or floors that weren’t built to resist fire
  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor

If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Surfaces we seal

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

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Landlords and agents in East End can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’ve already had a go yourself, that is fine. We cut it out and start again.

Fire rated sealant around East End

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For buildings such as St Margaret's Church, gaps around pipes and cables are worth checking after any building work there. Around East End, as everywhere, fire rated sealant is only as good as the preparation behind it.

How to look after the new joints

So the new joints stay in good condition:

  • Include hidden areas like risers in routine checks
  • Tell trades working in the building that fire seals must be put back
  • Never patch a fire seal with standard sealant
  • Plan fire stopping into any work that goes through walls or floors

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.
