Fire stopping in Ashfield, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers, and what we’re called in for most is seals that don’t match their tested detail and head-of-wall gaps with no fire seal. Facilities teams, main contractors and managing agents in Ashfield tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Ashfield, 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.

A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email us and we’ll arrange a return visit.

Cost factors for service penetrations

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

  • Distance, for remote addresses
  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • The product specified

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

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

  • Any dates the work must fit around
  • Specification clauses that apply
  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

When to bring in a specialist

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. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Ashfield can sit alongside others in a wider programme.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. 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. For a building around Ashfield, 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. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Flag any permit to work we will need
  • Send any specification or drawings in advance

Advice

What we can’t put right

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

  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on
  • Approving the work on behalf of building control

If you are not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Where we work in Ashfield

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

Signs you need fire stopping in Ashfield

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

It’s worth sending us details if you spot any of the following:

  • Fire-rated sealant that has cracked or shrunk back
  • Penetration schedules that need working through
  • Expanding foam used as fire stopping
  • Improvised or mixed-product fire seals

Campus buildings at universities such as University of Southampton, 4.1 miles south-east of Ashfield, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • Proof of insurance

Questions to ask before you appoint anyone

FAQs: Ashfield

Can you seal penetrations in a hotel in Ashfield after a refit?

Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Can work at a site such as University of Southampton fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do you work in Ashfield?

Yes. We take on work across Ashfield, with one number for every area we cover.

Fire stopping in Ashfield: the local picture

Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail. There are several hotels within about 2 miles of Ashfield. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

For a site team at a college like Totton College, which lies south-west of Ashfield, fire-rated sealing is best scheduled after the summer works. Where a unit on an estate such as Crescent Industrial Estate (1.1 miles south of Ashfield), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
