Trusted fire rated sealant in Cock Street

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

About our fire rated sealant in Cock Street

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. If you have fire seals that have cracked with movement and holes left by a change of layout, we can help, on plasterboard & masonry, pipe & cable gaps and linear gaps alike.

Work in a small place like Cock Street is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. Somewhere like Cock Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. Locations and products are noted so you have them on file.

Before we arrive

  • Clear the area around the work
  • Try not to wet indoor joints just before the visit
  • Let us know about parking restrictions

Advice

What the job involves on each surface

Door frames

Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist.

Plasterboard walls

We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.

Fire rated sealant in Cock Street: local notes

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.

Letting a property close to Bures station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Signs you need fire rated sealant in Cock Street

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

Keep an eye out for these signs:

  • Ordinary sealant used where a fire-rated product was needed
  • Door frames with gaps between frame and wall
  • Gaps flagged on a fire risk assessment
  • Fire seals that have cracked with movement

Community buildings like St Matthew's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Questions to ask before booking

  • Whether they’re fully insured
  • What the quote includes, VAT included or not
  • Whether all the old sealant comes out first
  • What guarantee comes with the work

Our hiring checklist

Leave it or put it right?

Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like Cock Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Why book with us

  • 20+ years of sealant experience
  • Full insurance on every job
  • 12-month guarantee on every job
  • An ARBOMaster approved applicator

Questions from Cock Street

Do you cover Cock Street for fire rated sealant?

Yes. We work across London and the South East, and Cock Street is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.

Do you cover smaller places like Cock Street?

Can new sealant go over the old?

No, because it fails. The old sealant always comes out first.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Will you assess my building’s fire safety?

No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and let us know what needs doing and where.

What sealant work cannot fix

We’d rather tell you now than do work that won’t last, so these are the limits:

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

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

Where we work in Cock Street

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

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Flag any open gap you spot round a pipe or cable
  • Allow for resealing whenever new services are run
  • Keep the record of products and locations with your fire safety documents
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
