Fire rated sealant for Fox homes and businesses

Fire rated sealant for homes and businesses in Fox

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on plasterboard & masonry, door frames and service penetrations, and the jobs we see most are fire seals that have cracked with movement and joints picked up in a fire-stopping survey.

Somewhere as small as Fox, 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 12-month guarantee.

For landlords and businesses

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Honest limits

We will always be straight with you, so here’s what new sealant won’t do:

  • Fire risk assessments, which need a qualified assessor
  • Problems with the door itself rather than the gap around the frame
  • Openings too large for sealant, which need batts, boards or another system

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

What we seal

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

Why it’s worth doing now in Fox

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Fox, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • We are fully insured
  • Any old sealant cut out fully, not covered over
  • Approved under the ARBOMaster scheme
  • Anti-fungal sanitary silicone in wet areas

Commercial buildings in Fox

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Amport Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

The process

A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Fox, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your files.

Getting ready for the visit

  • Move anything stored near the joints
  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in

Advice

Aftercare tips

Aftercare is simple, and it makes a real difference:

  • Ask which product was used before you paint
  • Keep the record of products and locations with your fire safety documents
  • Tell trades working in the building that fire seals must be put back
  • Take photos of fire stopping before ceilings or boxing go back

Any fire seal that’s cut or drilled needs resealing to its tested detail. 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.

When to call us in Fox

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Signs it’s time to call us include:

  • Open gaps behind door architraves
  • Old fire sealant that has split or come away
  • Ordinary sealant used where a fire-rated product was needed
  • Sealant items on a fire risk assessment action list

Letting a property close to Grateley station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Choosing a sealant specialist

Fox questions

Is Fox within the area you cover?

Yes. Fox is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is Fox in your area for fire rated sealant?

Yes, Fox is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.

Can you fill the gap behind a fire door frame?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.

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

No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.

Where do you work from?

We’re a Crawley-based firm. We work across South East England, London and Scotland.

Can you seal over the old sealant?

No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. We use whichever the specification and tested details call for.

Do you guarantee your work?

Yes, always. There’s a 12-month guarantee on every job.
