How we handle fire stopping in Hundridge

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal rather than guesswork. If you have snag lists that include open service penetrations and unsealed openings around new pipes and cables, we can put it right, whatever the surface. Most enquiries from Hundridge start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Barn and farm-building conversions near places like Hundridge often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Doing it in-house

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. That’s why many clients bring in a specialist from the beginning.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Service penetrations in Hundridge buildings

Central London is about 28 miles from Hundridge. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

For an estates team at a campus like Buckinghamshire New University, which lies south of Hundridge, summer M&E works are typically followed by a round of penetration sealing. Holiday works at schools like Hyde Heath Infant School often leave service openings to seal before pupils return. Tenant changes at parks like Waterside Business Park (to the east of Hundridge) bring new data and services, and openings through fire-resisting walls need the specified seal.

Hundridge is about 2 miles west of Chesham, in Buckinghamshire. We send applicators to Hundridge for service penetrations. Hundridge is one of 308 places in Buckinghamshire on our list. Sites around Reading have their own page, about 23 miles away.

Quoting for work in Hundridge

To price the job, we consider:

  • The size and state of each joint
  • Access and working height
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements

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 we will put a fixed figure on it.

What we need to price the job

However big the job, the same details help:

  • The asbestos register, for older buildings
  • When you need the work done
  • Specification clauses that apply
  • The type of building and who uses it

To get a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.

How the job changes by surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.

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 will never swap a specified collar for sealant.

Questions about Hundridge

Is Hundridge too small for you to travel to?

No. Places such as Hundridge are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Could you schedule work at a campus like Buckinghamshire New University for the vacation?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Which standards are fire seals tested to?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement.

Can you tell us what fire stopping our building needs?

No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Hundridge need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Point out any areas we must not close
  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work

Looking after the joints

Once the work is signed off, these steps help:

  • Get seals inspected before ceilings and boxing close
  • Keep product data and details in the fire safety file
  • Flag new cables with no seal around them
  • Check risers and ceiling voids after each round of works

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.

When something else is needed

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

  • Plastic pipes whose detail calls for a collar or wrap
  • Writing the fire-stopping specification
  • Fire doors, dampers or other fire safety equipment

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly.

Joints and surfaces we work on

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