Fire stopping for commercial buildings in Lullington

Facilities managers in Lullington often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. If you’re dealing with open linear gaps along the top of fire-resisting walls and fire stopping installed outside its tested range, we can put it right, whatever the surface. A single leaking joint is often how a building in Lullington first comes to us: we look at the rest while we are there and tell you what we find.

Rural conversions around Lullington 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.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Building owners, agents and FMs in Lullington

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lullington can sit alongside others in a wider programme across East Sussex.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Common problems we fix in Lullington

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Clients usually get in touch after noticing one or more of the following:

  • Unsealed penetrations discovered above suspended ceilings
  • Seals disturbed by maintenance and left open
  • Non-fire-rated filler around services
  • Improvised or mixed-product fire seals

Hospital estates such as Chailey Heritage Marine Hospital (4.3 miles west of Lullington) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Our contractor checklist

Your questions answered

Is Lullington too small for you to travel to?

Not at all. Lullington is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you take on work at healthcare sites like Chailey Heritage Marine Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Are you insured?

Yes. We’re fully insured, including public liability cover.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email the details over. Include photographs or drawings if you have them.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Fire stopping around Lullington: what changes locally

A 2-mile radius around Lullington takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Central London is about 49 miles from Lullington. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

In a building such as Church of St. Andrew, any service penetration through a fire-resisting wall should be sealed to the specified detail. Offices at parks like Berwick Court Farm Business Park (to the north of Lullington) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. 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. Smaller jobs around Lullington can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Arrange parking or a loading space
  • Tell staff and tenants when we will be in
  • Move anything stored against the joints

Advice

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Large openings beyond what any sealant detail covers
  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals

If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.

Surfaces we seal

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

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Older rural buildings around Lullington move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
