Honest limits

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Fire risk assessments, which need a qualified assessor
  • A wall that isn’t a fire-resisting element to begin with
  • 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.

Joints and surfaces we work on

  • Plasterboard & masonry

Fire rated sealant in Titmore Green

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. Common call-outs are for new service routes left unsealed after building work and old fire sealant that has split or come away, across linear gaps, service penetrations and door frames.

For holiday lets, converted business premises or a community building near Titmore Green, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Why deal with it now?

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. In a small place like Titmore Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What fire rated sealant looks like in Titmore Green

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.

Rented homes near Stevenage station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of St Mary the Virgin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Titmore Green 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. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Do you need fire rated sealant in Titmore Green?

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

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

  • Joints picked up in a fire-stopping survey
  • Ordinary sealant used where a fire-rated product was needed
  • Open joints along the top of partitions
  • Fire stopping disturbed by later work

For site and facilities teams at buildings such as Wymondley Junior Mixed and Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What your quote should include

  • Who does the work, and how experienced they are
  • What preparation is included
  • What happens if they find a problem under the old sealant
  • Whether they seal over old material or remove it

Choosing a sealant specialist

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Tell trades working in the building that fire seals must be put back
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Ask which product was used before you paint
  • Include hidden areas like risers in routine checks

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.
