Fire rated sealant in Bullsmoor

Looking after it afterwards

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

  • Don’t paint over fire sealant until it has cured
  • Take pictures of fire stopping before ceilings or boxing go back
  • Look in service cupboards and ceiling voids from time to time
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.

About our fire rated sealant in Bullsmoor

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. We work on service penetrations, plasterboard & masonry and door frames, and common reasons people get in touch are joints picked up in a fire-stopping survey and open gaps behind door architraves.

For a pub, café, guest house or shop in or near Bullsmoor, its washrooms and kitchen need the same sealant care as any big building.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Problems with the door itself rather than the gap around the frame
  • Sign-off of the building, which sits with building control or your assessor
  • Big openings where sealant alone isn’t the tested solution

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What we seal

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

Commercial buildings in Bullsmoor

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 work to the specification you are given, installing the product to its tested details.

Schools such as Honilands Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Community buildings like St George's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How the job changes by surface

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.

DIY versus a professional finish

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.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How the visit works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. Parking around Bullsmoor is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

Before we arrive

  • Keep children and pets away from the work area
  • Let us know about stairs, lifts or work at height
  • Tell us about any water getting in

What we’re called out for in Bullsmoor

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.

Look out for these signs:

  • Open holes round services passing through fire walls
  • Damaged fire sealant left by other trades
  • Gaps left after a refit or conversion
  • Fire seals that have cracked with movement

If you let a flat or house near Turkey Street station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
