Fire rated sealant in Netherton

We often work from an action list drawn up by a fire risk assessor on buildings across Netherton. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. Common call-outs are for gaps where walls meet ceilings or slabs and gaps filled with a product that isn’t fire-rated, on flats & HMOs, service penetrations and plasterboard & masonry.

Somewhere as small as Netherton, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Commercial buildings in Netherton

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

For buildings such as Church of St Nicholas, older buildings that have had new heating or wiring often have service gaps worth checking.

What the job involves on each surface

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we’ll flag it.

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product.

Quotes for fire rated sealant in Netherton

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

  • How much old sealant there is and how hard it is to remove
  • Working hours on commercial sites
  • Any mould that needs treating
  • How many rooms, windows or areas are involved

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Helping us quote

To make quoting easier, let us know:

  • What’s wrong with the joints now
  • If someone has resealed it before
  • The type of property
  • How we’d reach the joints

Need a quote? Please phone 0345 464 0079 or drop us an email with a few details. We will explain what we’d do and give you a clear price before work begins.

Honest limits

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • A wall that is not a fire-resisting element to begin with
  • Openings too large for sealant, which need batts, boards or another system
  • Assessing a building’s fire safety

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.

What we seal

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

When to call us in Netherton

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 looks sealed, but it is not fire-rated.

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

  • Gaps where walls meet ceilings or slabs
  • Gaps filled with a product that is not fire-rated
  • Fire stopping disturbed by later work
  • Old fire sealant that has split or come away

If you look after a building such as John Blandy Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Choosing a sealant specialist

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.

Common questions in Netherton

Is Netherton in your area for fire rated sealant?

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

Is Netherton within the area you cover?

Yes. Netherton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How much does fire rated sealant cost in Netherton?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

What’s the difference between intumescent and fire-rated sealant?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all and which one is used depends on the job.

Are you an approved applicator?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

I’m a tenant. Can you help?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Do you take on fire stopping in schools and offices?

Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Early starts or out-of-hours work can be arranged.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

How the visit works

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere like Netherton needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any leaks or damp you’ve noticed
  • Keep pets and children clear of the area while we work

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or send us an email.

Advice

Looking after it afterwards

Aftercare is simple:

  • Allow for resealing whenever new services are run
  • Look in service cupboards and ceiling voids from time to time
  • Report cracked or damaged seals as soon as you notice them
  • Keep pictures of seals that will be hidden

Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.
