Fire rated sealant near Homerton

Do you need fire rated sealant in Homerton?

In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.

If you can see any of these, it’s time to have the joints looked at:

  • Unsealed gaps where pipes and cables go through a wall
  • Sealant items on a fire risk assessment action list
  • Door frames with gaps between frame and wall
  • Ordinary sealant used where a fire-rated product was needed

Rented homes near Homerton station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions to ask before booking

  • How the surfaces are prepared before sealing
  • Is VAT in the price?
  • Which sealant they’ll use, and why
  • How long the guarantee is

Choosing a sealant specialist

About our fire rated sealant in Homerton

We often work from an action list drawn up by a fire risk assessor for buildings in Homerton. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on pipe & cable gaps, flats & HMOs and linear gaps, and people most often call us about ordinary sealant used where a fire-rated product was needed and open gaps behind door architraves.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Homerton, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What sealant work can’t fix

To be straight with you, there are a few things sealant won’t fix:

  • Large holes that need a different fire-stopping system
  • Problems with the door itself rather than the gap around the frame
  • 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 booking.

Surfaces we seal

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

How to look after the new joints

To keep the joints looking good and working properly:

  • Never patch a fire seal with standard sealant
  • Include hidden areas like risers in routine checks
  • Plan fire stopping into any work that goes through walls or floors
  • Keep the record of products and locations with your fire safety documents

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.

Why deal with it now?

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a flat in Homerton, 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.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Why book with us

  • ARBOMaster approved applicator
  • Trusted Arbo and Everbuild sealants
  • Tidy, careful work
  • Homes, businesses and hotels

Workplaces and buildings in Homerton

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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.

Community buildings like United Reformed Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as Rushmore Primary School, service openings in fire-resisting walls need checking after any refurbishment.

What we do, step by step

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. In a London area like Homerton, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Before we arrive

  • Mention any tricky access
  • Mention any leaks or damp you’ve noticed
  • Clear the area around the work

Homerton questions

Do you work for hotels and guest houses in Homerton?

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 Homerton?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Can new sealant go over the old?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status.

How long does fire rated sealant take?

Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer, and we will tell you how long to expect.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Will you leave a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Is standard sealant good enough for a fire gap?

No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.

Surface by surface

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.
