Fire stopping for businesses in Batt's Corner

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Surface by surface

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

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, including keys, permits and any isolations.

About our fire stopping in Batt's Corner

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or send details through our quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. If you have fire stopping installed outside its tested range and openings found when ceilings come down for a refit, we can help, on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors alike. Facilities teams, main contractors and managing agents in Batt's Corner tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Smaller places such as Batt's Corner 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.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Check risers and ceiling voids after each round of works
  • Don’t let anyone top up a fire seal with the wrong product
  • Brief every trade that openings they make must be sealed
  • Have penetrations checked while they can still be seen

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. 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. For a building around Batt's Corner, tell us how to find it and who will meet us. 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. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Flag any permit to work we’ll need
  • Send any specification or drawings in advance
  • Make sure the joints can be reached

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Do you need fire stopping in Batt's Corner?

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.

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

  • Old intumescent sealant that has split away
  • Unsealed joints where partitions meet the slab
  • Service penetrations left open after M&E works
  • Seals disturbed by maintenance and left open

For a unit at a site such as Blacknest Industrial Park (1.7 miles west of Batt's Corner), new power or data runs between office and warehouse can breach a compartment wall.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • How the existing material will be dealt with
  • Their plan for phasing and protecting the area
  • How joint depth will be controlled

How to choose a sealant contractor

Penetration seals near Batt's Corner

At about 39 miles from central London, Batt's Corner is within reach of the capital. 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. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

Large healthcare estates like Chase Community Hospital, 4.2 miles south of Batt's Corner, change their services often, so penetration seals are worth checking after M&E work. Residences at universities like University for the Creative Arts, 3.8 miles north of Batt's Corner, have compartment walls that must be resealed whenever services change.

Your questions answered

How does the move away from BS 476 affect penetration seals in Batt's Corner?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is a smaller place like Batt's Corner outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you hold CHAS accreditation?

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

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Quoting for work in Batt's Corner

A fixed quote reflects the actual work. It takes account of:

  • The site’s rules and procedures
  • Removal of failed or old sealant
  • Travel to remote or island sites
  • Which sealant the job calls for

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Where the site is, with the postcode
  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • Your programme or deadline

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.
