Fire rated sealant near Gosford

How we handle fire rated sealant in Gosford

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on flats & HMOs, service penetrations and pipe & cable gaps, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and unsealed gaps where pipes and cables go through a wall.

Somewhere as small as Gosford, 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.

Big or small, it’s backed by our 12-month guarantee in Gosford and across Oxfordshire.

Why act early in Gosford

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own. Older cottages and farmhouses around Gosford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Why us?

  • One-year guarantee on every job
  • Anti-fungal silicone where joints get wet
  • Rated 4.9 stars on Google
  • Quality sealants from Arbo and Everbuild

What affects the cost of fire rated sealant

We do not publish a price list, because jobs vary so much. What we look at:

  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • Which sealant suits the joint

What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Roughly how big the job is
  • Where the property is
  • A few photos by email, if you can
  • If someone has resealed it before

For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll give you a clear price before any work starts.

Fire rated sealant in Gosford: local notes

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

If you look after a church, hall or community building such as Saint John the Baptist Hall Church, service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Edward Feild Primary School? Then fire-stopping around service openings should be restored whenever new services go in. Rented homes near Oxford Parkway station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Work for landlords, hotels and businesses

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

Different surfaces, different methods

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment.

How it works

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are from start to finish. In a small place like Gosford, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Before we arrive

  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work
  • Mention if the joints have been sealed before

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

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

How long does fire rated sealant take?

Do you have insurance?

Yes. We are fully insured for domestic and commercial work.

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

No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service.

Can you work in occupied buildings?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged if that suits the building.

Can you give us a record of the work?

Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.

How to look after the new joints

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

  • Ask which product was used before you paint
  • Keep the record of products and locations with your fire safety documents
  • Ask every contractor to reseal any fire stopping they disturb
  • Include hidden areas like risers in routine checks

Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.
