Fire stopping for Marden Beech sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping in Marden Beech

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call 01277 525 020 or use the quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on cable penetrations, pipe penetrations and service gaps in risers, and the usual reasons a site gets in touch are old intumescent sealant that has split away and unsealed openings around new pipes and cables. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Marden Beech is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A job near Marden Beech is normally planned around one visit, 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.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sets the cost

To price the job, we consider:

  • Induction, permit and paperwork requirements
  • How accessible the joints are
  • How much existing material needs removing
  • Which sealant the job calls for

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Specification clauses that apply
  • Whether the building will be occupied during the work

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Reviewing a building’s overall fire safety

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

Surfaces we seal

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

Marden Beech: questions and answers

Is Marden Beech too far out for you?

No. Places such as Marden Beech are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

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

No. The designer or fire engineer sets the detail and building control accepts it. We install what’s specified, to the product’s tested detail.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we will set out a timescale with the quote.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a building around Marden Beech, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. 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.

What we need from you

  • Arrange parking or a loading space
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs

Advice

What the job involves on each surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.

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 outside it are raised with you.

Penetration seals near Marden Beech

At about 34 miles from central London, Marden Beech is within reach of the capital. 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. What we install is set by the specification, and it goes in to the tested detail.

For a building such as St Michael and All Angels Church, new heating or data runs are the usual reason penetrations need sealing. For a school such as Marden Primary School, penetration sealing fits best at the end of the summer works.

Marden Beech is about 8 miles south of Maidstone, in Kent. We send applicators to Marden Beech for service penetrations. Marden Beech is one of 931 places we cover in Kent for service penetrations. London is covered too, some 34 miles away.

Should maintenance staff do it?

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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Looking after the joints

After handover, these steps help:

  • Foam or ordinary sealant is never a fire-seal repair
  • Ask the designer to confirm details early on refits
  • Ask which product is in place before decorating
  • Get seals inspected before ceilings and boxing close

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open, not months later.
