Fire rated sealant for Wrotham homes and businesses

What affects the quote in Wrotham

We don’t publish a price list, because jobs vary so much. What we look at:

  • Whether there’s mould to deal with
  • Which sealant suits the joint
  • The amount of work
  • Working hours on commercial sites

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Helping us quote

You do not need to know the technical terms. It helps if you can tell us:

  • Whether it’s a home or a business
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved
  • Access, such as stairs, a lift or height

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or drop us an email.

Fire rated sealant for homes and businesses in Wrotham

Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you’re dealing with gaps flagged on a fire risk assessment and unsealed gaps around fire door frames, we can put it right, whatever the surface.

In a village or hamlet like Wrotham, 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.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Workplaces and buildings in Wrotham

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Letting a property close to Borough Green & Wrotham station? Then any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Church of St George, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Wrotham School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Landlord and commercial work in Wrotham

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Photograph sealed gaps before they’re covered up
  • Never patch a fire seal with standard sealant
  • File the fire-stopping record where your assessor can find it
  • Allow for resealing whenever new services are run

Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.

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.

What we do, step by step

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Wrotham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

Common questions in Wrotham

Is Wrotham in your area for fire rated sealant?

Yes. Our work covers London and the South East, and Wrotham is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Will you come out to Wrotham?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is standard sealant good enough for a fire gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.

Is the work guaranteed?

Yes, always. Each job is guaranteed for twelve months.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.

How do I get a quote for fire rated sealant in Wrotham?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us with a short description of the job.

Can I choose the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Honest limits

To be straight with you, some problems need a different trade:

  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor
  • Construction that does not provide fire resistance on its own

If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Where we work in Wrotham

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

Leave it or put it right?

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Older cottages and farmhouses around Wrotham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
