Fire stopping for Tangley sites

Fire stopping in Tangley

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you’re dealing with fire seals cut back for extra cables and never reinstated and expanding foam used as fire stopping, we can help. A single leaking joint is often how a building in Tangley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Tangley, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

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.

Questions we are asked in Tangley

What happens to BS 476 references for fire stopping in Tangley?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is Tangley too far out for you?

Not at all. Tangley is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

How long does a typical visit take?

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

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Fire-rated sealing for Tangley buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 64 miles from Tangley. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.

For a hospital such as Andover War Memorial Hospital (4.3 miles south of Tangley), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Tangley is about 5 miles north-west of Andover, in Hampshire. Our applicators travel to Tangley for work on service penetrations, handled exactly as we handle every other area. We work across 723 places in Hampshire. Sites around Southampton have their own page, roughly 25 miles from Tangley.

Postcode districts covered here: SP11. Sites close to Tangley are covered too, including Chute Forest (1 mile south-west), Hatherden (2 miles south-east), Upper Chute (2 miles west), Clanville (2 miles south) and Redenham (3 miles south-west). Nearby towns on our patch include Andover (5 miles south-east), Tidworth (6 miles west), Ludgershall (4 miles west), Whitchurch (9 miles east), East Anton (4 miles south-east) and Overton (12 miles east).

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Look above ceilings when tiles are lifted for other jobs
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Arrange inspection before areas are covered up
  • Agree the fire-stopping specification before services go in

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original unless the designer specifies otherwise.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open instead of being left for someone else.

Signs you need fire stopping in Tangley

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.

What tends to prompt an enquiry:

  • Expanding foam used as fire stopping
  • Fire sealant pulled out of the opening
  • Hidden openings found during inspections
  • Penetration schedules that need working through

Halls and meeting rooms at places like Church of St Thomas of Canterbury sometimes gain new services, and any compartment wall crossed needs the specified seal.

Before you book anyone

  • Who will actually carry out the work
  • Can the work be phased to keep areas open?
  • What level of public liability insurance do they hold?
  • The named product and why it was chosen

Choosing a commercial sealant contractor

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Converted and older buildings near places like Tangley tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • Travel to remote or island sites
  • Any access equipment needed
  • Phasing around occupants
  • Whether old sealant has to be cut out first

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Tangley, 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. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  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

  • Flag any permit to work we will need
  • Share your working hours and any access restrictions
  • Tell staff and tenants when we will be in
