Fire stopping in Hook Norton

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping in Hook Norton

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have fire-rated sealant that has cracked or shrunk back and non-fire-rated filler around services, we can put it right, on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations alike. One point of contact handles commercial sealant work in Hook Norton from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Around Hook Norton, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Work in places the size of Hook Norton is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When it isn’t the sealant

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

  • Construction that lacks the fire resistance the seal relies on
  • Large openings beyond what any sealant detail covers
  • Approving the work on behalf of building control

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Joints and surfaces we work on

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

Common questions from Hook Norton clients

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hook Norton?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is Hook Norton off your patch?

No. Places such as Hook Norton are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

How long does a typical visit take?

It depends on the scope, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What the job involves on each surface

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Settle who seals which penetrations at the start of a project
  • Don’t let anyone top up a fire seal with the wrong product
  • Flag new cables with no seal around them
  • Get seals inspected before ceilings and boxing close

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Penetration seals near Hook Norton

For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 69 miles from Hook Norton. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

In a building such as Church of St Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a school such as Hook Norton Church of England Primary School, penetration sealing fits best at the end of the summer works.

What affects the price in Hook Norton

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

  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Removal of failed or old sealant

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • The site address and postcode
  • Your programme or deadline
  • Specification clauses that apply
  • Photos of the joints, close up and from further back

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Why act early in Hook Norton

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
