Fire stopping for commercial buildings in Hillborough

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have unsealed joints where partitions meet the slab and builders’ foam or ordinary silicone in compartment walls, we can put it right, whatever the surface. A single leaking joint is often how a building in Hillborough first comes to us: we look at the rest while we are there and tell you what we find.

In places the size of Hillborough, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

How the quote is worked out

Before we quote, we look at:

  • The size and state of each joint
  • Induction, permit and paperwork requirements
  • How much existing material needs removing
  • Working within restricted access windows

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For a job in Hillborough, the main thing is a clear picture of the work. A fixed quote follows.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000
  • Share your working hours and any access restrictions

Fire stopping around Hillborough: points for this area

Hillborough has two care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified. Central London is about 55 miles from Hillborough. Office refits around the commuter belt bring new cabling through fire-resisting walls.

In a school such as Reculver Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified. For a hospital such as Queen Victoria Memorial Hospital, 1.2 miles west of Hillborough, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. Tenant changes at parks like Eddington Business Park, 2.1 miles to the west of Hillborough, bring new data and services, and openings through fire-resisting walls need the specified seal.

Hillborough is about 2 miles east of Herne Bay, in Kent. Any commercial site in Hillborough is covered, for single jobs and planned programmes alike. 931 places across Kent fall within our area, Hillborough among them. Our London page has more on work in that area.

What happens if it’s left?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Small buildings around Hillborough suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Common questions from Hillborough clients

Can you work in a care home near Hillborough with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hillborough?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

When it isn’t the sealant

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Approving the work on behalf of building control
  • Gaps in walls that were never built as compartment walls
  • Deciding what a wall or floor needs, which belongs to the designer

If in doubt, call 01277 525 020 or email us and we will say what we think.

Surfaces we seal

  • Pipe penetrations
  • Linear gaps at wall heads
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows
  • Joints between fire-resisting walls and floors
  • Cable penetrations

Looking after the joints

For the best life from the joints:

  • Get seals inspected before ceilings and boxing close
  • Put resealing into every M&E and fit-out package
  • Flag new cables with no seal around them
  • File the specified details where the next contractor can find them

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
