Fire stopping in Roughdown

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Fire stopping in Roughdown, done properly

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you are dealing with seals that don’t match their tested detail and expanding foam used as fire stopping, we can put it right, on cable penetrations, small duct penetrations where the tested detail allows and service gaps in risers alike. Facilities teams, main contractors and managing agents in Roughdown 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 Roughdown 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 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

When to call us in Roughdown

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.

What tends to prompt an enquiry:

  • Head-of-wall gaps with no fire seal
  • Non-fire-rated filler around services
  • Unsealed penetrations discovered above suspended ceilings
  • Seals that don’t match their tested detail

For a building at a site such as Glenmore Business Park (1.4 miles north of Roughdown), a check of penetration seals after each fit-out is good practice.

Questions to ask before you book

  • Who will actually carry out the work
  • How the existing material will be dealt with
  • What the guarantee covers, and for how long
  • Their approach to joint depth and backing

Choosing a commercial sealant contractor

What affects the price in Roughdown

Your fixed quote is built from the real scope. It allows for:

  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • How much existing material needs removing

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

What we need to price the job

The more we know, the firmer the quote. When you get in touch, include:

  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Where the site is, with the postcode
  • What the building is and how it’s used

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email the details over.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls
  • Issuing fire ratings or certificates for seals

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

What we seal

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

Fire-rated sealing for Roughdown buildings

Approved Document B is the English guidance that covers fire stopping around 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.

Schools such as Blackfield Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Theatres, wards and plant rooms at sites like Hythe Hospital (to the north of Roughdown) all have compartment walls crossed by services.

Roughdown is about 3 miles south of Hythe, in Hampshire. Across the SO45 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Hampshire coverage takes in 723 places. There’s a separate page for Southampton, roughly 7 miles from Roughdown.

Postcode districts covered here: SO45 for service penetrations. Nearby places we also cover include Holbury (1 mile north), Blackfield (1 mile east), Little Holbury (1 mile north), Langley (1 mile south-east) and Hardley (1 mile north). Further afield, our area takes in Gosport (10 miles east), Eastleigh (10 miles north), Fareham (9 miles east), Totton (9 miles north-west), Chandler's Ford (11 miles north) and Hedge End (8 miles north-east).

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For a building around Roughdown, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Let us know about inductions and permits
  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed

Roughdown: questions and answers

Is hospital work, at somewhere like Hythe Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can work at a site such as Totton College Waterside Centre fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you reseal penetrations after our M&E works?

Yes, provided a specification covers them. New services after M&E works often breach existing seals.

Do you work in Roughdown?

Yes. We take on work across Roughdown, and the same phone number covers every area.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Is BS 476 being phased out?

From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Product selection stays with your designer.

Will you write the fire-stopping specification?

No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Include service cupboards in routine inspections
  • Report damaged or disturbed seals as soon as they’re spotted
  • Foam or ordinary sealant is never a fire-seal repair
  • Settle who seals which penetrations at the start of a project

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
