Fire stopping in Oakley

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Fire stopping for commercial buildings in Oakley

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. Most enquiries involve damaged fire seals in risers and voids and expanding foam used as fire stopping, across linear gaps at wall heads, pipe penetrations and joints between fire-resisting walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Oakley, that means joint design, primers and backing rod as standard.

In places the size of Oakley, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common questions from Oakley clients

Do you cover business parks and estates near Oakley, such as Brighton Hill Retail Park?

Yes, sites like Brighton Hill Retail Park are within our area, along with the rest of Oakley. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do you take on work at healthcare sites like Park Prewett Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Can you fire stop behind the services contractors?

Yes, provided a specification covers them. New services after M&E works often breach existing seals, and we reseal them to the specified detail.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Cost factors for service penetrations

Before we quote, we look at:

  • How much existing material needs removing
  • How much there is to seal
  • Backing rod, priming and other preparation
  • Access and working height

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Access details, including height
  • The type of building and who uses it
  • When you need the work done
  • Whether an asbestos survey exists

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

Where services cross fire walls in Oakley

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. What we install is set by the specification, and it goes in to the tested detail. Oakley has two care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

Holiday works at schools like Oakley CE Junior School often leave service openings to seal before pupils return. For a unit at a site such as Brighton Hill Retail Park, 2.9 miles east of Oakley, any new service through a fire-resisting wall should be sealed to the tested detail.

Oakley is about 3 miles west of Basingstoke, in Hampshire. We cover commercial sites throughout Oakley. Oakley is one of 723 places we cover in Hampshire. We also cover Reading, around 16 miles from Oakley.

If you need fire stopping in RG23, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Station Road, Marlborough Gardens and Anton Close, and sites on any of them can send details for a fixed quote. Sites close to Oakley are covered too, including Newfound (1 mile north-east), Kempshott (2 miles east), Worting (2 miles north-east), Buckskin (2 miles east) and Ibworth (2 miles north). A short drive away, we cover Basingstoke (3 miles east), Winchester (15 miles south-west), Fleet (15 miles east), Andover (14 miles west), Alton (11 miles south-east) and Tadley (7 miles north).

Aftercare for building managers

After handover, these steps help:

  • Check risers and ceiling voids after each round of works
  • Settle who seals which penetrations at the start of a project
  • Check with the data sheet before painting over fire sealant
  • Have penetrations checked while they can still be seen

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.

Leave it or put it right?

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Signs you need fire stopping in Oakley

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

Typical triggers for a call:

  • Builders’ foam or ordinary silicone in compartment walls
  • Service penetrations left open after M&E works
  • Seals disturbed by maintenance and left open
  • Fire-rated sealant that has cracked or shrunk back

Hospital estates such as Park Prewett Hospital (3.2 miles north-east of Oakley) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Comparing quotes

  • How they’ll work around occupants
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS

Our contractor checklist

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Oakley need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Before we start on site

  • Point out any areas we must not close
  • Tell staff and tenants when we’ll be in
  • Send any specification or drawings in advance

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
