Fire rated sealant for Petworth homes and businesses

Fire rated sealant for homes and businesses in Petworth

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t 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 pipe & cable gaps, plasterboard & masonry and door frames, and the jobs we see most are open gaps behind door architraves and fire seals that have cracked with movement.

Somewhere as small as Petworth, 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.

Whatever the size of the job, you get the same one-year guarantee.

Is there any odour?

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

How long does the job take?

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.

What we cannot put right

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Large holes that need a different fire-stopping system
  • Sign-off of the building, which sits with building control or your assessor
  • A wall that isn’t a fire-resisting element to begin with

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

What we seal

  • Plasterboard & masonry

Fire rated sealant around Petworth

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. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For landlords with property near Pulborough station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Petworth Cof E Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

When to call us in Petworth

Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

Common reasons people contact us include:

  • Fire stopping disturbed by later work
  • Gaps left after a refit or conversion
  • Fire seals that have cracked with movement
  • Linear gaps at the head of walls

Community buildings like Sacred Heart Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Questions to ask before you book

  • Which colour the sealant will be
  • Is VAT in the price?
  • How the surfaces are prepared before sealing
  • What product goes in the joint

Choosing a sealant specialist

What we do, step by step

On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. The work normally takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Petworth, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

Preparing for the visit

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks

How to get a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.

Keeping the joints in good condition

Aftercare is simple:

  • Report cracked or damaged seals as soon as you notice them
  • Check risers, ceiling voids and cupboards during building checks
  • File the fire-stopping record where your assessor can find it
  • Check whether a sealant can be painted before decorating over it

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
