How we handle fire stopping in Dry Sandford

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. The enquiries we see most involve seals disturbed by maintenance and left open and improvised or mixed-product fire seals, across joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows. A specialist sealant contractor works differently from a general builder: in Dry Sandford, that means joint design, primers and backing rod as standard.

Around smaller places like Dry Sandford, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Approving the work on behalf of building control
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Reviewing a building’s overall fire safety

Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly.

Where we work in Dry Sandford

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

Different surfaces, different methods

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.

Metal pipes

Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.

From enquiry to sign-off

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Dry Sandford are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We start with your penetration schedule, drawings or specification.
  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 so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • Point out any areas we must not close

Advice

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Keep general-purpose fillers away from compartment walls
  • Flag new cables with no seal around them
  • Check with the data sheet before painting over fire sealant
  • Put resealing into every M&E and fit-out package

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open instead of being left for someone else.

Building owners, agents and FMs in Dry Sandford

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Questions we are asked in Dry Sandford

Will you take on work at estates like Wootton Business Park, close to Dry Sandford?

Yes. Estates, retail parks and business parks around Dry Sandford, Wootton Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Can work at a site such as Azad University in Oxford fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

How much does the work cost?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Is BS 476 being phased out?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you cover Dry Sandford?

Yes. We take on work across Dry Sandford.

Why deal with it now?

Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Around Dry Sandford, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

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.

Why us?

  • Clear, fixed quotes
  • Public liability insurance in place
  • Products installed to the manufacturer’s instructions
  • Sealing commercial buildings since 2005

Central London is about 55 miles from Dry Sandford. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B.

We install whatever has been specified, to the product’s tested detail.

Colleges such as Abingdon & Witney College: Abingdon Campus (to the south-east of Dry Sandford) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
