Fire rated sealant in Coldmoorholme

Coldmoorholme: your questions answered

Will you come out to Coldmoorholme?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work for landlords with property near Bourne End station?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.

Can you fill the gap behind a fire door frame?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.

Do you offer different sealant colours?

Usually, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.

Is it OK to seal over old sealant?

No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Which products do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done.

Fire rated sealant in Coldmoorholme: local notes

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Community buildings like St Mark are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Claytons Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Bourne End station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Why it’s worth doing now in Coldmoorholme

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 sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Coldmoorholme, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Combining jobs into one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.

What we do, step by step

You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere as small as Coldmoorholme, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your records.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Keep pets and children clear of the area while we work
  • Clear items away from the joints we are working on

What the job involves on each surface

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified.

Landlord and commercial work in Coldmoorholme

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

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.

Aftercare tips

Looking after new joints is easy:

  • Never patch a fire seal with standard sealant
  • Take pictures of fire stopping before ceilings or boxing go back
  • Flag any open gap you spot round a pipe or cable
  • Store the list of sealed gaps with your building paperwork

Do not 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.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Issuing a fire rating or certificate for a building
  • A wall that is not a fire-resisting element to begin with
  • Deciding what fire stopping a building needs

If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
