About our fire stopping in Seven Dials

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. If you have head-of-wall gaps with no fire seal and seals that don’t match their tested detail, we can help. For commercial sealant work in Seven Dials, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Fire-rated sealing in a place like Seven Dials is normally a single building at a time. Send the specification, drawings or photos of the openings and we’ll quote to suit.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

How the job changes by surface

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Reviewing a building’s overall fire safety
  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Surfaces we seal

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

FAQs: Seven Dials

What does the BS 476 change mean for fire-rated sealant in Seven Dials?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Can you seal penetrations in a hotel in Seven Dials after a refit?

Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Can you quote from photos?

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

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Diagnose, treat, 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. What matters most for a job in Seven Dials is a clear list of what needs doing. You’ll then get a fixed price for the work.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed
  • Arrange parking or a loading space

Fire stopping in Seven Dials: the local picture

Five care or nursing homes sit less than 2 miles from Seven Dials. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. Seven Dials has plenty of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

Industrial units on estates such as Centenary Industrial Estate (to the north-east of Seven Dials) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. For a site team at a college like Waterbear College Brighton, which lies south-east of Seven Dials, fire-rated sealing is best scheduled after the summer works.

Do you need fire stopping in Seven Dials?

Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

These are often picked up first by site or facilities staff:

  • Fire-stopping items raised at inspection or handover
  • Non-fire-rated filler around services
  • Fire-rated sealant that has cracked or shrunk back
  • Service penetrations left open after M&E works

On a hospital site such as The Montefiore Hospital (under half a mile west of Seven Dials), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
