Fire rated sealant around Burnt Oak

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.

For site and facilities teams at buildings such as The Annunciation RC Junior School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like John Keble Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Fire rated sealant in Burnt Oak

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on door frames, service penetrations and pipe & cable gaps, and the jobs we see most are gaps left after a refit or conversion and ordinary sealant used where a fire-rated product was needed.

In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Burnt Oak.

All our work comes with our 12-month guarantee, wherever you are in Greater London.

What affects the quote in Burnt Oak

You will get a clear quote before any work starts. It’s based on:

  • The product the joint needs
  • When we can work, for business premises
  • The size of the job
  • Whether there’s mould to deal with

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What to tell us for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • A few pictures by email, if you can
  • Roughly how big the job is
  • The type of property
  • What’s wrong with the joints now

For fire rated sealant in Burnt Oak, call 0345 464 0079 or send us an email. Tell us what the problem is and where, and we will agree the price before any work begins.

Leave it or put it right?

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Burnt Oak, the repair is bigger than the sealant job would have been.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Aftercare tips

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

  • Never patch a fire seal with standard sealant
  • Don’t paint over fire sealant until it has cured
  • Allow for resealing whenever new services are run
  • Store the list of sealed gaps with your building paperwork

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

Different surfaces, different methods

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail.

Masonry and concrete

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

Common questions in Burnt Oak

Do you cover Burnt Oak for fire rated sealant?

Yes, Burnt Oak is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.

Can parking be tricky for a visit in Burnt Oak?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Can you quote for more than one area?

Of course. Doing several areas at once is usually more efficient.

Are you an approved applicator?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can you seal over the old sealant?

No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Are you insured?

Yes. Full insurance covers our work.

Do you certify the fire stopping?

We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.

Does someone need to be in?

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

What we are called out for in Burnt Oak

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

These are the problems we are asked about most:

  • Gaps filled with a product that isn’t fire-rated
  • Cracked or shrunken fire-rated sealant
  • Linear gaps at the head of walls
  • Fire stopping disturbed by later work

As a London address, Burnt Oak can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What to look for in a quote

  • Whether the sealant suits the joint
  • What happens if the job turns out different
  • Whether they seal over old material or remove it
  • Is VAT in the price?

10 questions to ask before booking

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works.

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

How the visit works

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours for a handful of gaps, and longer for a whole building, depending on the amount of work. For a job in Burnt Oak, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Let us know about earlier repairs to the joints
  • Tell us about any water getting in
  • Clear items away from the joints we are working on
