Do you provide details of the products used?

Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that normally means someone at home.

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and giving you a record of where it went.

Will you assess my building’s fire safety?

No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Fire rated sealant in Dargate, done properly

Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That detail is what we take care over. If you’re dealing with open joints along the top of partitions and sealant items on a fire risk assessment action list, we can help, on flats & HMOs, door frames and service penetrations alike.

What we do, step by step

We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job normally 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 Dargate, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Any non-fire-rated filler is removed.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Try not to wet indoor joints just before the visit
  • Mention if the joints have been sealed before

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Commercial buildings in Dargate

If you run a hotel, guest house or holiday let in a coastal place like Dargate, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you’re given, installing the product to its tested details.

For buildings such as Church of St Michael, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Hernhill Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Report cracked or damaged seals as soon as you notice them
  • Tell trades working in the building that fire seals must be put back
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Check whether a sealant can be painted before decorating over it

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

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

Why it’s worth doing now in Dargate

If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In a small place like Dargate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What we can’t put right

In fairness, there are a few things sealant won’t fix:

  • Assessing a building’s fire safety
  • Problems with the door itself rather than the gap around the frame
  • Large holes that need a different fire-stopping system

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

Joints and surfaces we work on

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

What the job involves on each surface

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

Signs you need fire rated sealant in Dargate

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps where walls meet ceilings or slabs
  • Gaps left after a refit or conversion
  • Sealant items on a fire risk assessment action list
  • Unsealed gaps around fire door frames

Rented homes near Selling station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
