Fire stopping in Hattingley

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Hattingley, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve head-of-wall gaps with no fire seal and fire-stopping items raised at inspection or handover, across service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Hattingley, that means joint design, primers and backing rod as standard.

For a smaller site near Hattingley, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

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.

Why act early in Hattingley

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. Older rural buildings around Hattingley move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Why us?

  • One contact handling all your sites
  • Workmanship guaranteed for 12 months
  • CSCS-carded applicators
  • Joints cleaned back to sound surfaces

After the work

Once the work is signed off, a little attention goes a long way:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Check risers and ceiling voids after each round of works
  • Record which product was used where
  • Agree the fire-stopping specification before services go in

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

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 the job ends with a walk round and sign-off. Rural sites near Hattingley may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  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. Foam, ordinary sealant and debris come out.
  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

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Make sure the joints can be reached

Cost factors for service penetrations

We price every job individually. The main factors are:

  • Distance, for remote addresses
  • Working within restricted access windows
  • How much there is to seal
  • The site’s rules and procedures

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • A wide shot and a close-up of the area
  • The postcode of the building
  • Drawings or a marked-up plan, if available
  • Any specification or named product

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

Common problems we fix in Hattingley

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.

Things that typically lead to an enquiry:

  • Seals that don’t match their tested detail
  • Open linear gaps along the top of fire-resisting walls
  • Penetration schedules that need working through
  • Fire seals cut back for extra cables and never reinstated

Industrial units on estates such as Barton Industrial Estate, 1 mile to the north-west of Hattingley, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Questions to ask before you book

  • How the existing material will be dealt with
  • The named product and why it was chosen
  • Who will actually carry out the work
  • Are they CHAS accredited or on Constructionline?

Hattingley: questions and answers

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

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 a smaller place like Hattingley outside your area?

No. Places such as Hattingley are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Is colour matching possible?

It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Are you fully insured?

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

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Fire stopping around Hattingley: points for this area

Hattingley lies roughly 50 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. 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.

Schools such as Medstead Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. In a building such as Church of St Andrew, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Hattingley is about 5 miles west of Alton, in Hampshire. Across the GU34 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.
