Fire rated sealant in Great Hallingbury

Surface by surface

Service penetrations

Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth.

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for the gap we’re sealing.

About our fire rated sealant in Great Hallingbury

Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We work on flats & HMOs, linear gaps and door frames, and the jobs we see most are seals cut through by electricians, plumbers or data installers and old fire sealant that has split or come away.

Work in a small place like Great Hallingbury is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

You get a one-year guarantee, the same in Great Hallingbury as everywhere else we work.

How it works

The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. Somewhere like Great Hallingbury needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  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. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

What happens if it’s left?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Older cottages and farmhouses around Great Hallingbury can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

What sealant work can’t fix

A few problems are outside what sealant work can do:

  • Issuing a fire rating or certificate for a building
  • A wall that is not a fire-resisting element to begin with
  • Problems with the door itself rather than the gap around the frame

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

What fire rated sealant looks like in Great Hallingbury

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.

Letting a property close to Bishops Stortford station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Thorn Grove Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of St Giles are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • Include fire stopping when you schedule refits
  • Include hidden areas like risers in routine checks
  • Take photos of fire stopping before ceilings or boxing go back
  • Report cracked or damaged seals as soon as you notice them

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.

How we quote for fire rated sealant

There’s no set price list. The quote depends on:

  • How easy the joints are to reach
  • How much there is to do
  • Whether old sealant or filler has to be cut out
  • How many areas need sealing

Rather than a set price list, 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 we need to know

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Access, such as stairs, a lift or height
  • Whether it has been sealed before
  • Photos by email, if that’s easy

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, ring 0345 464 0079 or drop us an email.

Great Hallingbury: your questions answered

Is Great Hallingbury within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you work for landlords with property near Bishops Stortford station?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.

Is it OK to seal over old sealant?

No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

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. The door leaf and its hardware need a door specialist.

Can I use normal mastic around a pipe through a fire wall?

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

Will there be a smell?

Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

Do you guarantee your work?

Yes, always. Each job is guaranteed for twelve months, wherever you are.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
