Need fire stopping in Up Nately?

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

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

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.

About our fire stopping in Up Nately

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and cable penetrations, and the usual reasons a site gets in touch are penetration schedules that need working through and hidden openings found during inspections. Facilities teams, main contractors and managing agents in Up Nately tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural conversions around Up Nately 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.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Compartments and services around Up Nately

In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 42 miles from central London, Up Nately is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.

Holiday works at schools like Robert May's School often leave service openings to seal before pupils return. Industrial units on estates such as Hatch Industrial Park (1.6 miles west of Up Nately) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Questions we’re asked in Up Nately

Do you cover business parks and estates near Up Nately, such as Hatch Industrial Park?

Yes, sites like Hatch Industrial Park are within our area, along with the rest of Up Nately. A few photos and the unit address let us price the work.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Up Nately?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Can you work while the building is occupied?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Surface by surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Up Nately can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals.
  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

  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance
  • Point out parking and an unloading spot

Request a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Approving the work on behalf of building control
  • Fire risk assessments, a job for a competent assessor
  • Deciding what a wall or floor needs, which belongs to the designer

If in doubt, call the office on 01277 525 020 or email us and we will say what we think before you book.

Surfaces we seal

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

When to call us in Up Nately

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

Any of the following is a good reason to get the joints checked over:

  • Fire seals cut back for extra cables and never reinstated
  • Fire-stopping items raised at inspection or handover
  • Head-of-wall gaps with no fire seal
  • Seals that don’t match their tested detail

Older community buildings such as Church of St. Stephen that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Before you book anyone

  • How they handle RAMS and site documents
  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it
