Fire rated sealant in North Street

What affects the cost of fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • Whether old sealant or filler has to be cut out
  • When we can work, for business premises
  • Whether the work is at height
  • How much there is to do

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • How we’d reach the joints
  • Roughly how big the job is
  • A few photos by email, if you can
  • Whether it has been sealed before

We quote each job on its own. Simply phone 0345 464 0079 or email us and describe the job, and photos are welcome.

Fire rated sealant in North Street

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. If you have fire stopping disturbed by later work and gaps left after a refit or conversion, we can help.

Somewhere as small as North Street, 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.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Landlords, agents and businesses in North Street

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

We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

North Street: your questions answered

Is North Street within the area you cover?

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

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

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Will we have a record of what was sealed?

Yes. You get a list of where we worked and what we used to keep with your fire safety documents.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Are you an approved applicator?

Yes. We’re approved under the ARBOMaster scheme.

What should I tell you?

Let us know what needs doing and where. We will ask anything else we need to know.

Do you guarantee your work?

Yes. All our work carries our one-year guarantee.

What happens if it’s left?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a small place like North Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before we start.

What you get with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • An ARBOMaster approved applicator
  • Domestic, commercial and hotel work
  • Any old sealant cut out fully, not covered over

Different surfaces, different methods

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.

When it is not the sealant

It helps to know what we cannot do:

  • Doors that aren’t fire doors in the first place
  • Construction that doesn’t provide fire resistance on its own
  • Fire risk assessments, which need a qualified assessor

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

Surfaces we seal

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

How to look after the new joints

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

  • Make resealing part of every contractor’s brief
  • Ask which product was used before you paint
  • Take pictures of fire stopping before ceilings or boxing go back
  • Get damaged fire seals looked at promptly

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

How it works

We keep the work tidy and contained to the joints we’re treating. The job generally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like North Street, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules
  • Mention any leaks or damp you’ve noticed

How to get a quote

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.
