Fire rated sealant for homes and businesses in Langley Heath

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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 door frames with gaps between frame and wall and holes left by a change of layout, across flats & HMOs, linear gaps and pipe & cable gaps.

In a village or hamlet like Langley Heath, 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.

All our work comes with our 12-month guarantee, wherever you are in Kent.

What happens on the day

We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Langley Heath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Mention any parking rules near the property
  • Tell us about access, such as stairs, a lift or high-level joints

Surface by surface

Door frames

Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first.

Aftercare tips

So the new joints stay in good condition:

  • Check risers, ceiling voids and cupboards during building checks
  • Never patch a fire seal with standard sealant
  • Take pictures of fire stopping before ceilings or boxing go back
  • Keep the record of products and locations with your fire safety documents

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Common questions in Langley Heath

Do you cover Langley Heath for fire rated sealant?

Yes, Langley Heath is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.

Will you come out to Langley Heath?

Yes. Langley Heath is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you remove the old sealant?

Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

Where are you based?

Our base is in Crawley, and we work across South East England, London and Scotland.

Is it OK to seal over old sealant?

No. We remove every bit of old sealant first.

Do I have to be there?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

What does intumescent mean?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

Will you assess my building’s fire safety?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

What affects the cost of fire rated sealant

You’ll get a clear quote before any work starts. It takes into account:

  • The amount of work
  • When we can work, for business premises
  • Any mould that needs treating
  • Whether old sealant or filler has to be cut out

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • Access, such as stairs, a lift or height
  • The address or postcode of the job
  • Roughly how big the job is
  • If someone has resealed it before

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

Landlords, agents and businesses in Langley Heath

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Fire rated sealant around Langley Heath

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.

Schools such as Senacre Technology College are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Common problems we fix in Langley Heath

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 looks sealed, but it isn’t fire-rated.

The most common problems we see are:

  • Old fire sealant that has split or come away
  • Sealant items on a fire risk assessment action list
  • Gaps filled with a product that isn’t fire-rated
  • New service routes left unsealed after building work

For landlords with property near Hollingbourne station, any gap left by new services in shared walls should be closed with a fire-rated product.
