About our fire rated sealant in Greenhill

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That is the part we focus on. If you’re dealing with open holes round services passing through fire walls and holes left by a change of layout, we can put it right.

Commercial work around a smaller place like Greenhill usually means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Why act early in Greenhill

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In an older home around Greenhill, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Why us?

  • Domestic, commercial and hotel work
  • More than 20 years in sealant work
  • Quality sealants from Arbo and Everbuild
  • Fully insured

Workplaces and buildings in Greenhill

For seaside hotels, guest houses and holiday lets around Greenhill, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

Rented homes near Herne Bay station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Thornden Wood Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.

Flats and HMOs

Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance so residents know what to expect.

What happens on the day

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. Parking around Greenhill is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Let us know if you’ve seen damp or leaks
  • Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Greenhill

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Keep an eye out for any of the following:

  • Gaps filled with a product that is not fire-rated
  • Linear gaps at the head of walls
  • New service routes left unsealed after building work
  • Sealant items on a fire risk assessment action list

Community buildings like St Peter are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How to choose a mastic man

DIY sealant or a professional job?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

How long does fire rated sealant take?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer, and we will say how long yours will take.

Can you fill the gap behind a fire door frame?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.
