Fire stopping in Swerford

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you’re dealing with improvised or mixed-product fire seals and expanding foam used as fire stopping, we can put it right. Whoever orders the work in Swerford, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Swerford, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Where services cross fire walls in Swerford

Central London is about 67 miles from Swerford. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around 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.

For buildings in and around Swerford, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail. For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.

When it isn’t the sealant

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

  • Construction that lacks the fire resistance the seal relies on
  • Plastic pipes whose detail calls for a collar or wrap
  • Reviewing a building’s overall fire safety

If you are not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Where we work in Swerford

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

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Swerford 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. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Commercial clients in Swerford

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Certain joints really need a specialist: 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.

What affects the price in Swerford

A fixed quote reflects the actual work. It allows for:

  • Whether old sealant has to be cut out first
  • The product specified
  • Access and working height
  • Induction, permit and paperwork requirements

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

However big the job, the same details help:

  • Access details, including height
  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • Specification clauses that apply

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or use the quote form.

What the job involves on each surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. We follow whatever the detail requires and flag anything we can’t match.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

Common questions from Swerford clients

Is Swerford too far out for you?

No. Places such as Swerford are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Do you design the fire stopping for buildings in Swerford?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
