Service penetrations in Frittenden buildings

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Frittenden is about 39 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

In a school such as Frittenden Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified. Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Wherever services are added at a hospital such as Benenden Hospital (to the south of Frittenden) the compartment line has to be made good with the specified product.

Frittenden is about 9 miles south of Maidstone, in Kent.

Fire stopping in Frittenden

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, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you have builders’ foam or ordinary silicone in compartment walls and fire-rated sealant that has cracked or shrunk back, we can put it right. A single leaking joint is often how a building in Frittenden first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural conversions around Frittenden 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.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Surface by surface

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common questions from Frittenden clients

How does the move away from BS 476 affect penetration seals in Frittenden?

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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

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

Yes. Our area takes in Frittenden and its surroundings, with estates and business parks such as Barradale Farm Industrial Estate included. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you work in Frittenden?

Yes. We cover Frittenden and the rest of Kent, within our coverage of Greater London, South East England and Scotland. To discuss a job, call the office on 01277 525 020 or use the quote form.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. For a building around Frittenden, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  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. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Frittenden can form part of a wider programme across Kent.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

After the work

After handover, a little attention goes a long way:

  • Check with the data sheet before painting over fire sealant
  • Look above ceilings when tiles are lifted for other jobs
  • Record which product was used where
  • Treat an open penetration as a priority repair

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

What affects the price in Frittenden

Quotes vary with the job. It mainly depends on:

  • Removal of failed or old sealant
  • The total length or number of joints
  • The size and state of each joint
  • Whether the work must be split into stages

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Approximate linear metres or a joint schedule
  • When you need the work done
  • What the building is and how it’s used
  • The product your specification calls for

For a fixed quote, give us a call on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.
