Fire stopping for businesses in Nyton

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

Why act early in Nyton

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Nyton, rather than one at a time. Send photos of each area and we will quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • CHAS accredited
  • 12-month guarantee on workmanship
  • Old sealant cut out, never sealed over
  • A Constructionline member, so easy to vet

Fire stopping for commercial buildings in Nyton

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Most enquiries involve fire-stopping items raised at inspection or handover and fire stopping installed outside its tested range, across linear gaps at wall heads, cable penetrations and pipe penetrations. One point of contact handles commercial sealant work in Nyton from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places like Nyton, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

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

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. Jobs in and around smaller places like Nyton are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Agree which areas must stay open
  • Tell staff and tenants when we will be in
  • For older buildings, check the asbestos register before work

Advice

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Approving the work on behalf of building control
  • Fire risk assessments, a job for a competent assessor
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.

Joints and surfaces we work on

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

When to call us in Nyton

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.

What tends to prompt an enquiry:

  • Expanding foam used as fire stopping
  • Old intumescent sealant that has split away
  • Fire seals cut back for extra cables and never reinstated
  • Fire stopping installed outside its tested range

For an estates team at a campus like University of Chichester, 2.6 miles south-west of Nyton, summer M&E works are normally followed by a round of penetration sealing.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • How the existing material will be dealt with
  • What site paperwork they can supply
  • How they’ll work around occupants

Questions to ask before you appoint anyone

Questions we’re asked in Nyton

Will you work in a care home in Nyton without moving residents out?

Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.

Can you seal around new services in a hotel near Nyton?

Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Fire stopping in Nyton: the local picture

Nyton has several hotels close by, all within 2 miles. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Nyton is about 52 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Large healthcare estates like Bognor Regis War Memorial Hospital, 3.4 miles to the south of Nyton, change their services often, so penetration seals are worth checking after M&E work. On a site such as The Woodhorn Business Centre, 1.5 miles west of Nyton, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Nyton is about 4 miles north of Bognor Regis, in West Sussex. Any commercial site in Nyton is covered. Across West Sussex, 373 places are covered, Nyton among them. For work in that direction, see our Portsmouth page.

We cover the PO20 postcode districts. Nearby places we also cover include Westergate (1 mile south-east), Aldingbourne (1 mile west), Eastergate (1 mile east), Norton (1 mile north-west) and Crockerhill (1 mile north-west). Further afield, our area takes in Worthing (12 miles east), Bognor Regis (4 miles south), Chichester (5 miles west), Selsey (9 miles south-west), Littlehampton (7 miles east) and Lancing (15 miles east).

Keeping the joints sound

A few simple habits keep the new joints working:

  • Foam or ordinary sealant is never a fire-seal repair
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Look above ceilings when tiles are lifted for other jobs
  • Check with the data sheet before painting over fire sealant

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.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Different surfaces, different methods

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.

Metal pipes

Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
