Fire stopping near Belmont

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle fire stopping in Belmont

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. We work on joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are expanding foam used as fire stopping and old intumescent sealant that has split away. A single leaking joint is often how a building in Belmont first comes to us: we look at the rest while we are there and tell you what we find.

Fire-rated sealing in a place like Belmont is usually a single building at a time. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What happens if it’s left?

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Sealing commercial buildings since 2005
  • One phone line for London, the South East and Scotland
  • Fixed quotes based on photos, drawings or a visit
  • Failed material removed, not covered up

Take a look at our cost guide or our accreditations.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Writing the fire-stopping specification
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Reviewing a building’s overall fire safety

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Surfaces we seal

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

Fire stopping around Belmont: what changes locally

At about 53 miles from central London, Belmont is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

Where a unit on an estate such as Ivyhouse Industrial Estate, 1.4 miles north of Belmont, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Hotels like Chatsworth Hotel, 0.7 miles south-west of Belmont, are refurbished in phases, and each phase can open up compartment walls.

Belmont is about 1 mile south-east of Hastings, in East Sussex. Businesses, contractors and managing agents in Belmont use us for work on service penetrations, as part of our coverage of East Sussex.

Questions we’re asked in Belmont

Do you take on work at healthcare sites like Conquest Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Does your area include sites such as Ivyhouse Industrial Estate, near Belmont?

Yes, sites like Ivyhouse Industrial Estate are within our area, along with the rest of Belmont. Send details of the unit and the work through our quote form for a quick quote.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Do you approve fire stopping for building control?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do you work in Belmont?

Yes. Belmont is in our area. For a quote, phone 01277 525 020 or email a schedule or drawings.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Cost factors for service penetrations

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • The size and state of each joint
  • The product specified
  • Phasing around occupants

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

What to include in your enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • Specification clauses that apply
  • The site address and postcode
  • A wide shot and a close-up of the area
  • When you need the work done

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Several jobs near Belmont can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Arrange parking or a loading space
  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs

Related advice

What we’re called out for in Belmont

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

Clients typically get in touch after noticing something like this:

  • Open linear gaps along the top of fire-resisting walls
  • Non-fire-rated filler around services
  • Unsealed openings around new pipes and cables
  • Fire-rated sealant that has cracked or shrunk back

Tenant changes at centres like Priory Meadow Shopping Centre (less than half a mile south-west of Belmont) often mean new services through walls between units.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Their pre-qualification and accreditations
  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
