Fire rated sealant in Wokefield, done properly

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. If you have open gaps behind door architraves and open joints along the top of partitions, we can help, on door frames, linear gaps and service penetrations alike.

For a small place like Wokefield, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

Each job carries a 12-month guarantee.

Signs you need fire rated sealant in Wokefield

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

Keep an eye out for these signs:

  • Fire stopping disturbed by later work
  • Gaps left after a refit or conversion
  • Open joints along the top of partitions
  • Sealant items on a fire risk assessment action list

Managing a site like The Willink School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Our hiring checklist

Leave it or put it right?

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. Where a wall is exposed, as many are in small places like Wokefield, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What we do, step by step

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Wokefield, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

How to prepare

  • Clear items away from the joints we’re working on
  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints

DIY versus a professional finish

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.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Common questions in Wokefield

Is Wokefield within the area you cover?

Yes. Wokefield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you cover Wokefield for fire rated sealant?

Yes, Wokefield is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.

Do you carry out fire risk assessments?

No, assessment isn’t something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Does someone need to be in?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

What does intumescent mean?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.

Do you guarantee your work?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Can I use normal mastic around a pipe through a fire wall?

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

What the job involves on each surface

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified room by room.

Plasterboard walls

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

Honest limits

Before you book, it’s worth knowing the limits:

  • Issuing a fire rating or certificate for a building
  • Walls or floors that weren’t built to resist fire
  • Deciding what fire stopping a building needs

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