Fire rated sealant in Elmstead

Fire rated sealant in Elmstead

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. Typical jobs include unsealed gaps around fire door frames and gaps left after a refit or conversion, on flats & HMOs, door frames and plasterboard & masonry.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Elmstead can’t close.

What affects the cost of fire rated sealant

The quote reflects the job in front of us. We take into account:

  • When we can work, for business premises
  • The number and length of the joints
  • The product the joint needs
  • Any mould that needs treating

What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What we need to know

To help us quote quickly, let us know:

  • A few photos by email, if you can
  • Where the property is
  • Any previous sealing or DIY work
  • How we’d reach the joints

If you are in Elmstead and need fire rated sealant, call 0345 464 0079 or send us an email. Tell us what the problem is and where, and you’ll get a clear quote before any work starts.

Workplaces and buildings in Elmstead

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, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

If you look after a church, hall or community building such as Christ Church, older buildings that have had new heating or wiring often have service gaps worth checking. Elmstead is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Work for landlords, hotels and businesses

Letting agents and landlords in Elmstead can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.

Leave it or put it right?

Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Elmstead.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Why book with us

  • Anti-fungal sanitary silicone in wet areas
  • 20+ years of sealant experience
  • Quality sealants from Arbo and Everbuild
  • Full insurance on every job

Do you need fire rated sealant in Elmstead?

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

Keep an eye out for any of the following:

  • Gaps where walls meet ceilings or slabs
  • Gaps left after a refit or conversion
  • Unsealed gaps around fire door frames
  • Seals cut through by electricians, plumbers or data installers

If you look after a building such as Bullers Wood School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What to look for in a quote

  • Whether they seal over old material or remove it
  • Are they insured?

Our hiring checklist

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Flag any open gap you spot round a pipe or cable
  • Photograph sealed gaps before they’re covered up
  • Allow for resealing whenever new services are run
  • Check whether a sealant can be painted before decorating over it

Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so the item can be closed.

Elmstead: your questions answered

Do you work for landlords with property near Elmstead Woods station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.

Can you do fire rated sealant in Elmstead?

Yes, Elmstead is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.

Where are you based?

We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Do you certify the fire stopping?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.

Do you do fire sealant around door frames?

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

What do you need from me for a quote?

Let us know what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.

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

No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.

Is there any odour?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

The process

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Elmstead. It helps if you can point us to a visitor permit or a bay close to the door.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your files.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height
