Fire rated sealant near Radclive

Fire rated sealant in Radclive, 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. We work on flats & HMOs, pipe & cable gaps and linear gaps, and common reasons people get in touch are sealant items on a fire risk assessment action list and fire stopping disturbed by later work.

In a village or hamlet like Radclive, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

There’s a 12-month guarantee on every job, large or small.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Check whether a sealant can be painted before decorating over it
  • Make resealing part of every contractor’s brief
  • Keep photos of seals that will be hidden
  • Store the list of sealed gaps with your building paperwork

Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

What the job involves on each surface

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.

Plasterboard walls

We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.

Leave it or put it right?

Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Where a wall is exposed, as many are in small places like Radclive, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What you get with us

  • One-year guarantee on every job
  • Homes, businesses and hotels
  • Anti-fungal sanitary silicone in wet areas
  • Any old sealant cut out fully, not covered over

See our cost guide or our reviews.

What we can’t put right

It helps to know what we can’t do too:

  • Big openings where sealant alone isn’t the tested solution
  • Walls or floors that weren’t built to resist fire
  • Issuing a fire rating or certificate for a building

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

What affects the quote in Radclive

Your quote is based on your job. We look at:

  • The old material and how stubborn it is
  • When we can work, for business premises
  • How many areas need sealing
  • Mould in or behind the old joints

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Helping us quote

You don’t need to know the technical terms. Just tell us:

  • The problem you’ve noticed
  • Any access issues, like height or stairs
  • Whether it’s a home or a business
  • Roughly how big the job is

There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.

For landlords and businesses

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Questions from Radclive

Do you work for hotels and guest houses in Radclive?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Do you cover Radclive for fire rated sealant?

Yes. We work across London and the South East, and Radclive is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.

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

No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.

What does fire rated sealant cost?

Size, access and the old material all affect the cost. Ask us for a quote.

Does someone need to be in?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

Can you fill the gap behind a fire door frame?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door leaf and its hardware need a door specialist.

What should I tell you?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.

Is the work guaranteed?

Yes. All our work carries a 12-month guarantee.

What happens on the day

You don’t need to clear the whole room or building before we come, just the space around the work. 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. For a village or hamlet like Radclive, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

How to prepare

  • On commercial sites, let us know about site rules
  • Tell us about any water getting in
  • Let us know about earlier repairs to the joints

Fire rated sealant in Radclive: local notes

There are hotels and other places to stay in and around Radclive. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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 work to the specification you’re given, installing the product to its tested details.

For buildings such as Church of St John, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Royal Latin School, service openings in fire-resisting walls need checking after any refurbishment.
