Fire rated sealant in Wivelsfield, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. We work on pipe & cable gaps, service penetrations and door frames, and the jobs we see most are cracked or shrunken fire-rated sealant and gaps flagged on a fire risk assessment.

For holiday lets, converted business premises or a community building near Wivelsfield, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Our work is backed for twelve months, in Wivelsfield and everywhere else we cover.

What happens if it’s left?

Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. Around Wivelsfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What affects the cost of fire rated sealant

We quote each job individually. These are the things that affect it:

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

What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

What to tell us for a quote

To make quoting easier, let us know:

  • Photos by email, if that is easy
  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • The rough size of the job

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.

What happens on the day

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Wivelsfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  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.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Mention any tricky access
  • Where the joints are inside, avoid wetting them before we arrive

Fire rated sealant around Wivelsfield

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.

Rented homes near Wivelsfield station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Ote Hall Chapel, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Wivelsfield Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Is intumescent sealant the same as fire-rated sealant?

Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Should I try DIY first?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Do you do fire sealant around door frames?

Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.

Do you hold any approvals?

Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Honest limits

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Deciding what fire stopping a building needs
  • Issuing a fire rating or certificate for a building
  • A wall that is not a fire-resisting element to begin with

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

Joints and surfaces we work on

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

Can I do it myself?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Store the list of sealed gaps with your building paperwork
  • Allow for resealing whenever new services are run
  • Take photos of fire stopping before ceilings or boxing go back
  • Do not fill fire-stopping gaps with ordinary foam or silicone

Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
