Fire rated sealant in Jarvis Brook

Fire rated sealant in Jarvis Brook

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. Common call-outs are for unsealed gaps around fire door frames and fire seals that have cracked with movement, on plasterboard & masonry, flats & HMOs and pipe & cable gaps.

In a village or hamlet like Jarvis Brook, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. In a small place like Jarvis Brook, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed 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

  • Let us know about parking restrictions
  • Tell us about access, such as stairs, a lift or high-level joints
  • Where the joints are inside, avoid wetting them before we arrive

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

FAQs for Jarvis Brook

Can you help a landlord with a rental near Crowborough station?

Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

Will you come out to Jarvis Brook?

Yes, Jarvis Brook is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

How long does fire rated sealant take?

Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.

Is standard sealant good enough for a fire gap?

No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Which products do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Where are you based?

Our base is Crawley. Our area covers South East England, London and Scotland.

When something else is needed

A few problems are outside what sealant work can do:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire risk assessments, which need a qualified assessor
  • Openings too large for sealant, which need batts, boards or another system

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

What we seal

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

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Allow for resealing whenever new services are run
  • Include hidden areas like risers in routine checks
  • Take pictures of fire stopping before ceilings or boxing go back
  • Report cracked or damaged seals as soon as you notice them

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

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

Do you need fire rated sealant in Jarvis Brook?

In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.

If you can see any of these, it’s time to have the joints looked at:

  • Cracked or shrunken fire-rated sealant
  • Holes left by a change of layout
  • Open holes round services passing through fire walls
  • Door frames with gaps between frame and wall

Schools such as Jarvis Brook Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
