About our fire rated sealant in Cudworth

Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you are dealing with gaps where walls meet ceilings or slabs and sealant items on a fire risk assessment action list, we can put it right, whatever the surface.

In a village or hamlet like Cudworth, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Your questions about fire rated sealant in Cudworth

Can you help a landlord with a rental near Holmwood station?

Yes. We work for letting agents and landlords as well as householders. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.

Will you come out to Cudworth?

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.

Will the old sealant be removed?

Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Is it OK to seal over old sealant?

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Is there a guarantee?

Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

What’s the difference between intumescent and fire-rated sealant?

An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.

How long does the job take?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll say how long yours will take.

Surface by surface

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.

Signs you need fire rated sealant in Cudworth

Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Signs it’s time to call us include:

  • Cracked or shrunken fire-rated sealant
  • Sealant items on a fire risk assessment action list
  • Ordinary sealant used where a fire-rated product was needed
  • Unsealed gaps around fire door frames

Letting a property close to Holmwood station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Choosing a sealant specialist

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

When something else is needed

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

  • Certifying a building or signing off its fire safety
  • Deciding what fire stopping a building needs
  • A wall that is not a fire-resisting element to begin with

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

Surfaces we seal

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

How the visit works

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on how many gaps there are, depending on how much there is to do. Somewhere like Cudworth 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. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can
  • Keep children and pets away from the work area

Advice

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Check risers, ceiling voids and cupboards during building checks
  • Plan fire stopping into any work that goes through walls or floors
  • Ask every contractor to reseal any fire stopping they disturb
  • Photograph sealed gaps before they’re covered up

Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Workplaces and buildings in Cudworth

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 work to the specification you are given, installing the product to its tested details.

Schools such as Newdigate CofE Endowed Aided Infant School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there.
