Fire stopping in The Hangers

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

What affects the price in The Hangers

We price every job individually. The things that drive the figure:

  • How much there is to seal
  • The product specified
  • Any access equipment needed
  • Removal of failed or old sealant

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Photos of the joints, close up and from further back
  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings
  • The type of building and who uses it

For a fixed quote, give us a call on 01277 525 020 or email drawings and photos with the site address and an outline of the work. Our quote form is another easy route.

Fire stopping in The Hangers, done properly

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. Most enquiries involve seals disturbed by maintenance and left open and builders’ foam or ordinary silicone in compartment walls, on service gaps in risers, joints between fire-resisting walls and floors and pipe penetrations. Facilities teams, main contractors and managing agents in The Hangers tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like The Hangers, 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. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building around The Hangers, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  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. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.

Preparing the site

  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints

Advice

Fire stopping around The Hangers: what changes locally

Central London is about 60 miles from The Hangers. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. 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.

For a building at a site such as Swanmore Business Park (1.8 miles south of The Hangers), a check of penetration seals after each fit-out is good practice.

The Hangers is about 6 miles north-east of Hedge End, in Hampshire. Businesses, contractors and managing agents in The Hangers can call on us for service penetrations, as part of our coverage of Hampshire. The Hangers is one of 723 places in Hampshire on our list for service penetrations. There’s a separate page for Southampton, about 10 miles away.

Site staff or a sealant specialist?

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

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Questions we’re asked in The Hangers

Is The Hangers too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

How does the move away from BS 476 affect penetration seals in The Hangers?

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.

What do you charge?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Does weather matter for sealant 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.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

How do we ask for a quote?

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

What the job involves on each surface

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.

When to call us in The Hangers

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access usually bring them to light.

Things that normally lead to an enquiry:

  • Service penetrations left open after M&E works
  • Fire seals cut back for extra cables and never reinstated
  • Fire stopping installed outside its tested range
  • Openings found when ceilings come down for a refit

Schools such as Bishops Waltham Infant School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • How they handle RAMS and site documents
  • Whether old or failed sealant will be cut out, not overlaid
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

After the work

Keep the joints in good shape with a few simple steps:

  • Arrange inspection before areas are covered up
  • Foam or ordinary sealant is never a fire-seal repair
  • Report damaged or disturbed seals as soon as they’re spotted
  • Check risers and ceiling voids after each round of works

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.

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.
