Trusted fire rated sealant in Sharnal Street

What the job involves on each surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before the sealant goes in.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.

Fire rated sealant in Sharnal Street, done properly

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We work on flats & HMOs, service penetrations and plasterboard & masonry, and common reasons people get in touch are new service routes left unsealed after building work and linear gaps at the head of walls.

In a village or hamlet like Sharnal Street, 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.

We stand behind the work with a 12-month guarantee.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Keep the record of products and locations with your fire safety documents
  • Get damaged fire seals looked at promptly
  • Ask which product was used before you paint
  • Take pictures of fire stopping before ceilings or boxing go back

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot, so ask us which we used.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.

Workplaces and buildings in Sharnal Street

For seaside hotels, guest houses and holiday lets around Sharnal Street, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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.

If you let a flat or house near Gillingham (Kent) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Margaret, service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like High Halstow Primary Academy? Then fire-stopping around service openings should be restored whenever new services go in.

FAQs for Sharnal Street

Can you help a landlord with a rental near Gillingham (Kent) station?

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Will you come out to Sharnal Street?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you take on fire stopping in schools and offices?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.

How long does fire rated sealant take?

A typical job takes a few hours for a handful of gaps, and longer for a whole building. We will confirm how long when we quote.

Do you seal gaps around fire door frames?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do I have to be there?

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

Is there a guarantee?

Yes. Every job comes with our one-year guarantee.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. Somewhere like Sharnal Street 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. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  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.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive

Quotes for fire rated sealant in Sharnal Street

We quote each job individually. This is what makes a difference:

  • Any mould that needs treating
  • The size of the job
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out

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

Asking for a quote

When you contact us, it’s useful to know:

  • Any access issues, like height or stairs
  • How many joints, rooms or windows are involved
  • If someone has resealed it before
  • What’s wrong with the joints now

Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Why act early in Sharnal Street

Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. Around Sharnal Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

  • Sanitary silicone with an anti-fungal additive in wet areas
