Trusted fire rated sealant in Newton Longville

What we can’t put right

Before you book, it’s worth knowing the limits too:

  • Certifying a building or signing off its fire safety
  • Openings too large for sealant, which need batts, boards or another system
  • Construction that does not provide fire resistance on its own

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

What we seal

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

Fire rated sealant in Newton Longville

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. If you’re dealing with fire seals that have cracked with movement and linear gaps at the head of walls, we can put it right, on linear gaps, door frames and pipe & cable gaps alike.

Somewhere as small as Newton Longville, 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.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we’re called out for in Newton Longville

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.

It’s worth asking for a quote if you see:

  • Damaged fire sealant left by other trades
  • Ordinary sealant used where a fire-rated product was needed
  • Sealant items on a fire risk assessment action list
  • Unsealed gaps where pipes and cables go through a wall

For buildings such as Church of St Faith, gaps around pipes and cables are worth checking after any building work there.

Choosing a sealant specialist

What affects the cost of fire rated sealant

You will get a clear quote before work begins. It takes into account:

  • The number of rooms or windows
  • The old material and how stubborn it is
  • When we can work, for business premises
  • Access and height

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • Roughly how big the job is
  • The address or postcode of the job
  • If it’s domestic, commercial or a hotel
  • How we’d reach the joints

For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved.

How the visit works

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Newton Longville, access is normally the main thing to plan. 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.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions
  • For business premises, tell us about site rules or sign-in

How to get a quote

We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or email us with the details, and pictures are welcome.

What happens if it’s left?

For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. In a small place like Newton Longville, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Newton Longville questions

Will you come out to Newton Longville?

Yes, we do. 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.

Can you do fire rated sealant in Newton Longville?

I rent my home. Can I book you?

Do you work in flats, HMOs and commercial buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we will plan around it.

What fire rating will the seal have?

We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
