Do you need fire stopping in Newchapel?

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Look out for the following:

  • Open linear gaps along the top of fire-resisting walls
  • Fire stopping installed outside its tested range
  • Fire sealant pulled out of the opening
  • Penetration schedules that need working through

Tenant changes at parks like Scanda-Hus Business Park, 1.1 miles east of Newchapel, bring new data and services, and openings through fire-resisting walls need the specified seal.

What your quote should include

  • Proof of insurance
  • Whether their applicators hold CSCS cards
  • How they handle RAMS and site documents
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Fire stopping in Newchapel, done properly

Facilities managers in Newchapel often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it. Where there isn’t one, the designer or fire engineer needs to set one first. If you have non-fire-rated filler around services and head-of-wall gaps with no fire seal, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Newchapel tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Newchapel is typically planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or use the quote form and we will come back to it.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Approving the work on behalf of building control

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.

Joints and surfaces we work on

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

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Questions we’re asked in Newchapel

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is hospital work, at somewhere like Queen Victoria Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Ask which product is in place before decorating
  • Include service cupboards in routine inspections
  • File the specified details where the next contractor can find them
  • Arrange inspection before areas are covered up

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Penetration seals near Newchapel

At about 23 miles from central London, Newchapel is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Hospital estates such as Queen Victoria Hospital, 2.8 miles south-east of Newchapel, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a school such as Imberhorne School, penetration sealing fits best at the end of the summer works.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Newchapel can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.
