Fire stopping across Hawkenbury

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Hawkenbury are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  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. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance
  • Make sure the joints can be reached

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email us.

Fire stopping in Hawkenbury

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. We work on pipe penetrations, cable penetrations and linear gaps at wall heads, and the failures we’re asked to look at most are openings left by services added after handover and non-fire-rated filler around services. Facilities teams, main contractors and managing agents in Hawkenbury tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Hawkenbury, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Cost factors for service penetrations

To price the job, we consider:

  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation
  • Working within restricted access windows

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • The site address and postcode
  • A wide shot and a close-up of the area
  • When you need the work done
  • What the building is and how it’s used

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or send details through our quote form.

How the job changes by surface

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.

Looking after the joints

A few simple habits keep the new joints working:

  • Keep general-purpose fillers away from compartment walls
  • File the specified details where the next contractor can find them
  • Check with the data sheet before painting over fire sealant
  • Report damaged or disturbed seals as soon as they’re spotted

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

Hawkenbury: questions and answers

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

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Does your area include sites such as Barradale Farm Industrial Estate, near Hawkenbury?

Yes. We cover Hawkenbury and the area around it, including industrial estates, business parks and retail parks such as Barradale Farm Industrial Estate. Photos and a short description are enough for a first look.

What do you charge?

Every job gets its own fixed quote. For yours, ring 01277 525 020 or email us.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Is colour matching possible?

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 confirm what’s available for the specified product when we quote.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Common problems we fix in Hawkenbury

Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

These are often picked up first by site or facilities staff:

  • Snag lists that include open service penetrations
  • Unsealed penetrations discovered above suspended ceilings
  • Unsealed joints where partitions meet the slab
  • Expanding foam used as fire stopping

For a unit at a site such as Barradale Farm Industrial Estate (1.3 miles east of Hawkenbury), new power or data runs between office and warehouse can breach a compartment wall.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether their applicators hold CSCS cards
  • Their plan for phasing and protecting the area
  • The named product and why it was chosen

Our contractor checklist

What happens if it’s left?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Hawkenbury. Photos of every joint help us quote for the whole job.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why us?

  • Constructionline member for supplier checks
  • Joints cleaned back to sound surfaces
  • Public liability insurance in place
  • 12-month guarantee on workmanship

Fire stopping around Hawkenbury: points for this area

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.
