Fire rated sealant in Rainham

How we handle fire rated sealant in Rainham

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. Common call-outs are for open gaps behind door architraves and sealant items on a fire risk assessment action list, on flats & HMOs, service penetrations and linear gaps.

Washrooms in busy buildings wear their sealant out faster than a bathroom at home, while fire-rated sealant has to be made good whenever new pipes or cables go through. In Rainham, timings are planned around the building.

Our work is backed for twelve months, in Rainham and everywhere else we cover.

Workplaces and buildings in Rainham

For seaside hotels, guest houses and holiday lets around Rainham, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

For buildings such as Church of St Margaret, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as St Margaret's Church of England Junior School, gaps opened by contractors for new cabling are a common finding in schools and offices.

How the job changes by surface

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required.

Signs you need fire rated sealant in Rainham

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common.

People usually contact us when they notice something like this:

  • Seals cut through by electricians, plumbers or data installers
  • Joints picked up in a fire-stopping survey
  • Unsealed gaps where pipes and cables go through a wall
  • Gaps left after a refit or conversion

Rented homes near Rainham (Kent) station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Will you leave a mess?

No, assessment isn’t something we do. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.

Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.

Why act early in Rainham

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Rainham, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.

The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What we do, step by step

On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. The work generally takes a few hours for a handful of gaps, and longer for a whole building. A visit in Rainham needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.

  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 and the faces cleaned.
  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

  • Tell us if parking is tricky
  • Move anything stored near the joints
  • Mention any leaks or damp you’ve noticed

Advice

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Keep photos of seals that will be hidden
  • Include fire stopping when you schedule refits
  • Ask every contractor to reseal any fire stopping they disturb
  • Keep the record of products and locations with your fire safety documents

Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is generally a straightforward job.

DIY versus a professional finish

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

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
