About our fire rated sealant in Westbourne Green

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. We work on service penetrations, pipe & cable gaps and linear gaps, and the jobs we see most are holes left by a change of layout and standard silicone or caulk in a fire-stopping gap.

In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Westbourne Green, we agree timings and access before anything starts.

Each job carries a 12-month guarantee, large or small.

Westbourne Green questions

Do you work for hotels and guest houses in Westbourne Green?

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.

Can parking be tricky for a visit in Westbourne Green?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Do you guarantee your work?

Yes. All our work carries a 12-month guarantee.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.

Are you insured?

Yes. We’re fully insured, with over 20 years’ experience in sealant work.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can I choose the sealant colour?

Generally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.

Where is Mr Mastic based?

Mr Mastic is based in Crawley. Our applicators cover Westbourne Green, along with the rest of our area.

Aftercare tips

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

  • Make resealing part of every contractor’s brief
  • Get damaged fire seals looked at promptly
  • Photograph sealed gaps before they’re covered up
  • Never patch a fire seal with standard sealant

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we will tell you which one you have.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What happens if it’s left?

For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. In a flat in Westbourne Green, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Fire rated sealant around Westbourne Green

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

If you look after a church, hall or community building such as St Mary Magdalene, gaps around pipes and cables are worth checking after any building work there. Rented homes near London Paddington station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. Westbourne Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

  • Large holes that need a different fire-stopping system
  • Walls or floors that weren’t built to resist fire

What happens on the day

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. In a London area like Westbourne Green, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts
  • Clear items away from the joints we’re working on

Advice

How the job changes by surface

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service to make sure it suits the product.
