Fire rated sealant in Cliffe

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. Common call-outs are for unsealed gaps around fire door frames and gaps filled with a product that isn’t fire-rated, on service penetrations, plasterboard & masonry and flats & HMOs.

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

Big or small, you get the same 12-month guarantee in Cliffe and across Medway.

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

When to call us in Cliffe

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common.

Most people get in touch after spotting something like this:

  • Gaps filled with a product that is not fire-rated
  • Fire stopping disturbed by later work
  • Gaps where walls meet ceilings or slabs
  • Unsealed gaps around fire door frames

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

Questions to ask before you book

  • Whether you can choose the colour
  • What the quote includes, VAT included or not
  • What insurance they hold
  • What the cure time is

Choosing a sealant specialist

Aftercare tips

Looking after new joints is easy, and it makes a real difference:

  • Include fire stopping when you schedule refits
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Tell trades working in the building that fire seals must be put back
  • Keep the record of products and locations with your fire safety documents

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.

What affects the quote in Cliffe

We quote each job individually. These are the things that affect it:

  • How easy the joints are to reach
  • The size of the job
  • Any working-time requirements on site
  • The product the joint needs

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Helping us quote

To make quoting easier, let us know:

  • If someone has resealed it before
  • A few photos by email, if you can
  • Access, such as stairs, a lift or height

Is there a guarantee?

Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

Do you certify the fire stopping?

Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Do you do fire sealant around door frames?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

The process

You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes from a few hours to a few days, depending on the number of gaps and the access in most cases. In a small place like Cliffe, access is usually the main thing to plan. 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. Unsuitable material such as ordinary foam or silicone is cut out.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

Preparing for the visit

  • Mention any parking rules near the property
  • Mention any tricky access
  • Try not to wet indoor joints just before the visit
