Fire rated sealant in Ockham

Fire rated sealant in Ockham

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We work on pipe & cable gaps, service penetrations and plasterboard & masonry, and the jobs we see most are new service routes left unsealed after building work and open joints along the top of partitions.

In a village or hamlet like Ockham, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. 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’ll sort it.

Common questions in Ockham

I let a flat near Horsley station. Can you help?

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

Is Ockham in your area for fire rated sealant?

Yes. We work across London and the South East, and Ockham is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.

Do you guarantee your work?

Yes. There’s a 12-month guarantee on every job, wherever you are.

Do you offer different sealant colours?

Most of the time, yes. We’ll tell you which colours the right product comes in.

Where do you work from?

We work from Crawley. We cover Ockham and the rest of Surrey, along with the rest of our area.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Opening a window helps.

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

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

What we’re called out for in Ockham

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Look out for these signs:

  • Fire seals that have cracked with movement
  • Open joints along the top of partitions
  • Fire stopping disturbed by later work
  • Door frames with gaps between frame and wall

Rented homes near Horsley station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Choosing a sealant specialist

Looking after it afterwards

To keep the joints looking good and working properly:

  • Photograph sealed gaps before they’re covered up
  • Look in service cupboards and ceiling voids from time to time
  • Ask which product was used before you paint
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

How we quote for fire rated sealant

Jobs vary more than people expect. The main factors:

  • The number and length of the joints
  • Whether there’s mould to deal with
  • The number of rooms or windows
  • Any working-time requirements on site

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Asking for a quote

When you contact us, these details help:

  • The address or postcode of the job
  • Whether it’s a home or a business
  • Roughly how big the job is
  • Any previous sealing or DIY work

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

What the job involves on each surface

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the sealant bonds.

Can I do it myself?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How the visit works

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 from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Ockham, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Mention any tricky access
  • On commercial sites, let us know about site rules

Community buildings like All Saints' Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Ripley Court School? Then fire-stopping around service openings should be restored whenever new services go in.
