Fire stopping for Beaulieu sites

Fire stopping in Beaulieu, done properly

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Site teams most often ask us about damaged fire seals in risers and voids and snag lists that include open service penetrations, on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors. Looking for mastic applicators who cover Beaulieu? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Barn and farm-building conversions near places like Beaulieu often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Our workmanship is guaranteed for 12 months, in Beaulieu as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered

Is a smaller place like Beaulieu outside your area?

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

Can you work at a site such as Hardley Industrial Estate, by Beaulieu?

Yes. We cover Beaulieu and the area around it, including industrial estates, business parks and retail parks such as Hardley Industrial Estate. Photos and a short description are enough for a first look.

Can you seal any opening with fire-rated sealant?

No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed, as set out by the designer.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Why it’s worth doing now in Beaulieu

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Halls, stores and units around places like Beaulieu may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

What sealant work can’t fix

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Construction that lacks the fire resistance the seal relies on
  • Deciding what a wall or floor needs, which belongs to the designer

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Joints and surfaces we work on

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

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Ask which product is in place before decorating
  • Put resealing into every M&E and fit-out package
  • Record which product was used where
  • Include service cupboards in routine inspections

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Service penetrations in Beaulieu buildings

A 2-mile radius around Beaulieu takes in a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

Where a unit on an estate such as Hardley Industrial Estate (2.8 miles north-east of Beaulieu), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a hotel such as Montagu Arms Hotel (less than half a mile south-west of Beaulieu), penetration seals are worth checking after any refit or services upgrade. Workshops and IT rooms at colleges like Totton College Waterside Centre (to the north-east of Beaulieu) are re-serviced often, leaving penetrations to seal.

Beaulieu is about 4 miles south-west of Hythe, in Hampshire.

Commercial clients in Beaulieu

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Smaller jobs around Beaulieu can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Agree which areas must stay open
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements
