About our fire stopping in Princelett

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers, and the usual reasons a site gets in touch are non-fire-rated filler around services and open linear gaps along the top of fire-resisting walls. One point of contact handles commercial sealant work in Princelett from the first photos to the final walk-round, whether it’s one building or several.

Barn and farm-building conversions near places like Princelett often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Should maintenance staff do it?

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.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Rural sites near Princelett may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  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

  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Penetration seals near Princelett

Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Plenty of hotels sit less than 2 miles from Princelett. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

For a hospital such as Arthur Webster Memorial Hospital for Children, which lies south-east of Princelett, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. For a school such as Sandown Bay Academy, penetration sealing fits best at the end of the summer works.

Princelett is about 5 miles south-east of Newport, in the Isle of Wight.

What we’re called out for in Princelett

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

Common reasons buildings call us in:

  • Seals that don’t match their tested detail
  • Seals disturbed by maintenance and left open
  • Open linear gaps along the top of fire-resisting walls
  • Old intumescent sealant that has split away

Hotels like Apse Manor Country Hotel, 0.6 miles to the south of Princelett, are refurbished in phases, and each phase can open up compartment walls.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • The terms of the workmanship guarantee

Our contractor checklist

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • Whether the building will be occupied during the work

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or use the quote form.

What the job involves on each surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area.

FAQs: Princelett

Is a smaller place like Princelett outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Branstone Business Park, close to Princelett?

Yes. Our area takes in Princelett and its surroundings, with estates and business parks such as Branstone Business Park included. A few photos and the unit address let us price the work.

Can you seal any opening with fire-rated sealant?

No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we will tell you when that applies.

What do you charge?

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

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you fire stop behind the services contractors?

Yes, provided a specification covers them. New services after M&E works often breach existing seals, and we reseal them to the specified detail.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
