Service penetrations in Pickhurst buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Either way, we install the specified product to its tested detail. At about 40 miles from central London, Pickhurst is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

For a site team at a college like Brinsbury College, 1.9 miles to the north-east of Pickhurst, fire-rated sealing is best scheduled after the summer works. Offices at parks like Broomers Hill Business Park, 1.1 miles east of Pickhurst, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Pickhurst is about 11 miles south-west of Horsham, in West Sussex.

How we handle fire stopping in Pickhurst

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Pickhurst. If you’re dealing with expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated, we can put it right. Whoever orders the work in Pickhurst, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For a smaller site near Pickhurst, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

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.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Ask which product is in place before decorating
  • Foam or ordinary sealant is never a fire-seal repair
  • Ask the designer to confirm details early on refits
  • Make fire stopping part of every scope that crosses a fire-resisting wall

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.

What the job involves on each surface

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Your questions answered

Will you take on work at estates like Broomers Hill Business Park, close to Pickhurst?

Yes. Our area takes in Pickhurst and its surroundings, with estates and business parks such as Broomers Hill Business Park included. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Can work at a site such as Brinsbury College fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is any job too small?

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

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What do BS EN 1366-3 and BS EN 13501-2 mean?

The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

What we are called out for in Pickhurst

Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.

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

  • Unsealed joints where partitions meet the slab
  • Expanding foam used as fire stopping
  • Service penetrations left open after M&E works
  • Snag lists that include open service penetrations

In a hotel such as Chequers Hotel, 1.3 miles south of Pickhurst, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Comparing quotes

  • The terms of the workmanship guarantee
  • Whether their applicators hold CSCS cards
  • Whether primer will be used where the manufacturer specifies it
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

For managing agents and facilities managers

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. Rural sites near Pickhurst may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Move anything stored against the joints
  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs

Getting a fixed quote

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

What sets the cost

Each job is priced on its own details. The main factors are:

  • The size and state of each joint
  • Working within restricted access windows
  • Distance, for remote addresses
  • The product specified

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Details that help us quote

We can often quote from photos and a few details. It helps to include:

  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back
  • Any specification or named product
  • Rough lengths or quantities, or drawings if you have them

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or send details through our quote form.
