Fire stopping across Northney

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle fire stopping in Northney

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. If you’re dealing with old intumescent sealant that has split away and penetration schedules that need working through, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Northney is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural conversions around Northney can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Northney, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  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.

Getting the site ready

  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached

Advice

Why it’s worth doing now in Northney

Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Older rural buildings around Northney 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, because the scope varies so much from one building to the next. Call for a quote.

What sets the cost

What shapes the price:

  • Joint width, depth and condition
  • The total length or number of joints
  • Phasing around occupants
  • Which sealant the job calls for

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.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Whether the building will be occupied during the work
  • Any dates the work must fit around
  • How the joints are reached, and at what height
  • Clear photographs of the problem areas

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or use the quote form.

Fire-rated sealing for Northney buildings

A 2-mile radius around Northney 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. Northney is about 60 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

In a hotel such as Ropemaker Hotel, 1.4 miles north of Northney, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Hospital estates such as Elmleigh Hospital, 2.1 miles north of Northney, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Where a unit on an estate such as Finchwood Farm Industrial Estate, 1 mile south of Northney, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Don’t let anyone top up a fire seal with the wrong product
  • Include service cupboards in routine inspections
  • File the specified details where the next contractor can find them
  • Leave fire sealant to cure fully before covering it

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Questions about Northney

Is hospital work, at somewhere like Elmleigh Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you seal penetrations in a hotel in Northney after a refit?

Yes, where fire-rated sealant is the specified product. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.
