About our fire stopping in Perrywood

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. We work on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations, and the failures we are asked to look at most are unsealed joints where partitions meet the slab and hidden openings found during inspections. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Perrywood, that means joint design, primers and backing rod as standard.

Rural conversions around Perrywood can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

The 12-month guarantee covers our workmanship: 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.

How the quote is worked out

We price every job individually. The main factors are:

  • Access and working height
  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • The site’s rules and procedures

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • What the building is and how it’s used
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule

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.

Commercial clients in Perrywood

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Perrywood: questions and answers

Do you decide the fire-stopping details for buildings in Perrywood?

No, that sits with the designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Surface by surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.

Fire stopping around Perrywood: how the place shapes the job

In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Perrywood is about 47 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Holiday works at schools like Selling Church of England Primary School often leave service openings to seal before pupils return.

Perrywood is about 4 miles south-east of Faversham, in Kent. Our applicators travel to Perrywood for work on service penetrations. We work across 931 places in Kent, from busy centres to rural villages. Our London page has more on work in that area.

Do you need fire stopping in Perrywood?

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

Any of the following is a good reason to get the joints checked over:

  • Penetration schedules that need working through
  • Hidden openings found during inspections
  • Old intumescent sealant that has split away
  • Improvised or mixed-product fire seals

In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Before you book anyone

  • How the existing material will be dealt with
  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
  • How joint depth will be controlled

Our contractor checklist

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a single visit for a short list of penetrations, or a phased programme for a whole building. If others near Perrywood need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Confirm the product named in the specification
  • Let building users know which areas are affected
  • Make sure the joints can be reached
