Fire stopping in Sutton-under-Brailes

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 fire-rated sealant that has cracked or shrunk back and unsealed penetrations discovered above suspended ceilings, we can help. Whoever orders the work in Sutton-under-Brailes, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Sutton-under-Brailes still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Different surfaces, different methods

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.

Cables and cable bundles

New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail.

Service penetrations in Sutton-under-Brailes buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Wherever services are added at a hospital such as Ellen Badger Hospital (to the north-west of Sutton-under-Brailes) the compartment line has to be made good with the specified product. Halls and meeting rooms at places like St Thomas a Becket Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Sutton-under-Brailes are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  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.

Preparing the site

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Sutton-under-Brailes can sit alongside others in a wider programme across Oxfordshire.

Questions we’re asked in Sutton-under-Brailes

Would you work within a site like Ellen Badger Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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 work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How do I request a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Include photos or drawings if you have them.

What will the job cost?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or email drawings and photos.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Cost factors for service penetrations

These are the things that shape the price:

  • Access and working height
  • Site requirements such as inductions and permits
  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants

A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.

What we need to price the job

A few photographs plus some basic facts will normally do. It helps to include:

  • How the joints are reached, and at what height
  • The site address and postcode
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

When to call us in Sutton-under-Brailes

Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access usually bring them to light.

If one of these sounds familiar, it’s time for a closer look:

  • Fire stopping installed outside its tested range
  • Fire-rated sealant that has cracked or shrunk back
  • Penetration schedules that need working through
  • Non-fire-rated filler around services

Where a unit on an estate such as Brailes Industrial Estate, 1.6 miles north-east of Sutton-under-Brailes, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

What your quote should include

  • Can the work be phased to keep areas open?
  • How joint depth will be controlled
  • What the guarantee covers, and for how long
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Approving the work on behalf of building control
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.

Joints and surfaces we work on

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