How to look after the new joints

After the cure time, these simple habits help:

  • Photograph sealed gaps before they’re covered up
  • Store the list of sealed gaps with your building paperwork
  • Don’t paint over fire sealant until it has cured
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

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

Can I do it myself?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Signs you need fire rated sealant in Sheffield Bottom

Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

The most common problems we see are:

  • Gaps filled with a product that is not fire-rated
  • Old fire sealant that has split or come away
  • Holes left by a change of layout
  • Damaged fire sealant left by other trades

Schools such as Theale C.E. Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Choosing a sealant specialist

Fire rated sealant around Sheffield Bottom

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.

Community buildings like Church of the Holy Trinity are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For landlords with property near Theale station, any gap left by new services in shared walls should be closed with a fire-rated product.

Surface by surface

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length leaving no stretch unsealed.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.

How it works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Sheffield Bottom needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Tell us if parking is tricky
  • Let us know about earlier repairs to the joints
  • For indoor joints, keep the area dry beforehand if you can

  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out

The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.

Asking for a quote

To make quoting easier, please include:

  • If someone has resealed it before
  • A few pictures by email, if you can

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved.

Your questions about fire rated sealant in Sheffield Bottom

I let a flat near Theale station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Is Sheffield Bottom within the area you cover?

Yes, Sheffield Bottom is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

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

No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.

Do you take out the old sealant first?

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

What do you need from me for a quote?

A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
