About our fire rated sealant in Old Town

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you’re dealing with open holes round services passing through fire walls and standard silicone or caulk in a fire-stopping gap, we can help, whatever the surface.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Old Town cannot close.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

The process

You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. In Old Town, as in most of London, parking needs a little planning. 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. Each gap is measured and its substrate and service noted.
  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. Every location is recorded with the product used.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks

Different surfaces, different methods

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

FAQs for Old Town

I let a flat near West Croydon station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.

Do you work for hotels and guest houses in Old Town?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

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. We use whichever the specification and tested details call for.

Do you work in Old Town?

We do. Old Town is part of the area we cover.

Can you tell me which gaps need fire stopping?

No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

What should I tell you?

A short description and the location, with pictures by email if possible. We will ask anything else we need to know.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

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.

Commercial buildings in Old Town

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 are given, installing the product to its tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.

Rented homes near West Croydon station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Old Town is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Ask every contractor to reseal any fire stopping they disturb
  • Get damaged fire seals looked at promptly
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Plan fire stopping into any work that goes through walls or floors

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.

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

  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out

What to tell us for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • What’s wrong with the joints now
  • How we’d reach the joints
  • The type of property
  • Photos by email, if that is easy

Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved and give you a clear price.

Do you need fire rated sealant in Old Town?

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

It’s worth asking for a quote if you see:

  • Damaged fire sealant left by other trades
  • Gaps filled with a product that is not fire-rated
  • Gaps left after a refit or conversion
  • Unsealed gaps around fire door frames

If you look after a building such as The Minster Nursery and Infant School, fire-stopping around service openings should be restored whenever new services go in.

What your quote should include

  • What happens if they find a problem under the old sealant
  • Whether all the old sealant comes out first
  • Who does the work, and how experienced they are
  • Whether you can choose the colour

Choosing a sealant specialist

Should I try it myself first?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
