Fire rated sealant for Bucknell homes and businesses

What we cannot put right

To be straight with you, there are a few things sealant will not fix:

  • A wall that is not a fire-resisting element to begin with
  • Issuing a fire rating or certificate for a building
  • Problems with the door itself rather than the gap around the frame

If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

What we seal

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

Fire rated sealant for homes and businesses in Bucknell

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. We work on flats & HMOs, door frames and linear gaps, and people most often call us about cracked or shrunken fire-rated sealant and holes left by a change of layout.

Somewhere as small as Bucknell, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. 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.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What fire rated sealant looks like in Bucknell

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.

Rented homes near Bicester North station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as Gagle Brook Primary School, fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Bucknell, 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 and the gap 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.

How to prepare

  • Tell us if parking is tricky
  • For business premises, tell us about site rules or sign-in
  • For indoor joints, keep the area dry beforehand if you can

What affects the quote in Bucknell

The price is agreed before any work begins. It takes into account:

  • The old material and how stubborn it is
  • The product the joint needs
  • Any working-time requirements on site
  • How much there is to do

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What to tell us for a quote

To help us quote quickly, let us know:

  • Photos by email, if that’s easy
  • How we’d reach the joints
  • Any previous sealing or DIY work
  • The type of property

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

Why it’s worth doing now in Bucknell

Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. In a small place like Bucknell, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What you get with us

  • A 12-month guarantee on all work
  • 20+ years of sealant experience
  • Domestic, commercial and hotel work
  • Approved under the ARBOMaster scheme

Questions from Bucknell

I let a flat near Bicester North station. Can you help?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.

Is Bucknell within the area you cover?

Yes, Bucknell is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can I add another job to the visit?

Yes. More than one area can go on one quote.

Can new sealant go over the old?

No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

Can ordinary silicone be used in a fire-stopping gap?

No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Do you offer different sealant colours?

We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

What does fire rated sealant cost?

Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.

How to look after the new joints

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

  • Check whether a sealant can be painted before decorating over it
  • Include fire stopping when you schedule refits
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Tell trades working in the building that fire seals must be put back

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.

How the job changes by surface

Flats and HMOs

Conversions generally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. We follow the manufacturer’s tested detail for each and we flag any that need another system.
