How to look after the new joints

A little care helps the new joints last. Our advice:

  • Get damaged fire seals looked at promptly
  • Allow for resealing whenever new services are run
  • Keep photos of seals that will be hidden
  • Keep the record of products and locations with your fire safety documents

Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

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

Fire rated sealant in Norbury, done properly

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on door frames, pipe & cable gaps and service penetrations, and the jobs we see most are seals cut through by electricians, plumbers or data installers and new service routes left unsealed after building work.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Norbury cannot close.

Big or small, it’s backed by our 12-month guarantee.

FAQs for Norbury

Do you work for landlords with property near Norbury station?

Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.

Is parking a problem for a job in Norbury?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Can new sealant go over the old?

No. The old sealant always comes out first, so the new sealant bonds properly.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Should I try DIY first?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

What does fire rated sealant cost?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email and tell us what needs doing and where.

Do you take on fire stopping in schools and offices?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.

Honest limits

New sealant cannot fix everything, and we will tell you before work begins. It will not solve:

  • Openings too large for sealant, which need batts, boards or another system
  • Issuing a fire rating or certificate for a building
  • Fire doors that need new seals, closers or hardware

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Surfaces we seal

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

Why it’s worth doing now in Norbury

Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that doesn’t depend on other work. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Norbury.

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Why book with us

  • Approved under the ARBOMaster scheme
  • Anti-fungal silicone where joints get wet
  • Experience in homes, commercial sites and hotels
  • Tidy, careful work

Fire rated sealant in Norbury: 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, 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. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.

For site and facilities teams at buildings such as Kensington Avenue Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Norbury station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. As a London address, Norbury can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Advice

How we quote for fire rated sealant

The quote reflects the job in front of us. We look at:

  • When we can work, for business premises
  • How many rooms, windows or areas are involved
  • The number and length of the joints
  • How easy the joints are to reach

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • What’s wrong with the joints now
  • Photos by email, if that’s easy
  • Any previous sealing or DIY work
  • Roughly how big the job is

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.

Can I do it myself?

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.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

How the job changes by surface

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
