Fire stopping for Lamberhurst sites

How we handle fire stopping in Lamberhurst

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Lamberhurst. If you are dealing with seals that don’t match their tested detail and unsealed joints where partitions meet the slab, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Lamberhurst from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places like Lamberhurst, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Walls or floors that aren’t fire-resisting to begin with
  • Reviewing a building’s overall fire safety

Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly.

Surfaces we seal

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

Different surfaces, different methods

Metal pipes

Heat travels along metal pipework, and some details add wrapping or a set length of insulation. We follow whatever the detail requires and flag anything we can’t match.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer, and we’ll say if that applies.

Building owners, agents and FMs in Lamberhurst

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

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

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Backing rod, priming and other preparation
  • The product specified
  • Quantities, in metres or numbers
  • Any access equipment needed

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Whether an asbestos survey exists
  • When you need the work done
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or send photos by email.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Lamberhurst, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification
  • Arrange parking or a loading space

Advice

Service penetrations in Lamberhurst buildings

At about 35 miles from central London, Lamberhurst is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. 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. Either way, we install the specified product to its tested detail.

For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing. Hospital estates such as Ticehurst House Hospital, 3.5 miles south of Lamberhurst, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Lamberhurst is about 6 miles south-east of Royal Tunbridge Wells, in Kent. Lamberhurst sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Kent coverage takes in 931 places, from busy centres to rural villages. We also cover Brighton, some 29 miles away.

Work on service penetrations is covered throughout TN3, for business premises of every kind. Streets here include High Street, Church Road and Clivedon Court. Just outside Lamberhurst, we also work in Lamberhurst Quarter (2 miles north-west), Key's Green (3 miles north-west), Petteridge (3 miles north), Brenchley (4 miles north) and Matfield (4 miles north).

Aftercare for building managers

To get the most from the new sealant:

  • Keep product data and details in the fire safety file
  • Treat an open penetration as a priority repair
  • Check with the data sheet before painting over fire sealant
  • Don’t let anyone top up a fire seal with the wrong product

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Your questions answered

Would you work within a site like Ticehurst House Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like Lamberhurst outside your area?

Not at all. Lamberhurst is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What will the job cost?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or send photos by email with a description of the work.

Do you seal openings left by new services?

Yes. Send the schedule or marked-up drawings and the specified product details and a fixed quote follows. Work can run area by area behind the M&E trades.

Is it fine to apply new sealant on top of old?

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.

How many days will you need on site?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

How do we ask for a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
