Fire stopping in New Town, done properly

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. Site teams most often ask us about old intumescent sealant that has split away and hidden openings found during inspections, on joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows. Whoever orders the work in New Town, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as New Town still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

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.

What the job involves on each surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

From enquiry to sign-off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in 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 New Town, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Let us know about inductions and permits
  • Arrange parking or a loading space
  • Share the asbestos register for older buildings

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

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

Fire stopping around New Town: points for this area

For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. There are a number of hotels within about 2 miles of New Town. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Hospital estates such as Battle Hospital, 5.7 miles to the east of New Town, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Halls and meeting rooms at places like St Stephen's Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

New Town is about 7 miles west of Reading, in West Berkshire. Any commercial site in New Town is covered, for single jobs and planned programmes alike. Across West Berkshire, 140 places are covered, including New Town. Sites around Reading have their own page, roughly 7 miles from New Town.

Common questions from New Town clients

Is New Town too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Battle Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Is the work guaranteed?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Do you take on small jobs?

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

What does an EI 60 rating mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Are you insured?

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

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Plastic pipes whose detail calls for a collar or wrap
  • Signing off or certifying a building’s fire stopping

If you’re not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.

What we seal

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

What we are called out for in New Town

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

Clients normally get in touch after noticing something like this:

  • Unsealed penetrations discovered above suspended ceilings
  • Expanding foam used as fire stopping
  • Openings left by services added after handover
  • Damaged fire seals in risers and voids

For a school such as Basildon C.E. Primary School, penetration sealing fits best at the end of the summer works.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • Is the sealant right for the movement and the substrate?
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
