Fire stopping in Boldre

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have unsealed joints where partitions meet the slab and seals disturbed by maintenance and left open, we can put it right, whatever the surface. Whoever orders the work in Boldre, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For a smaller site near Boldre, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Ask the designer to confirm details early on refits
  • Flag new cables with no seal around them
  • Keep general-purpose fillers away from compartment walls
  • File the specified details where the next contractor can find them

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Common questions from Boldre clients

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Boldre?

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 a smaller place like Boldre outside your area?

No. Places such as Boldre are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can one quote cover more than one building?

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

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

How long do sealant joints last?

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

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months on every job.

Compartment walls and floors in Boldre

The area within 2 miles of Boldre holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Approved Document B is the English guidance that covers fire stopping around 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. We install whatever has been specified, to the product’s tested detail.

For a hotel such as Passford House Hotel, which lies west of Boldre, penetration seals are worth checking after any refit or services upgrade. Schools such as William Gilpin Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. On a hospital site such as Lymington New Forest Hospital, 0.8 miles to the south of Boldre, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Boldre is about 2 miles north of Lymington, in Hampshire. We cover Boldre and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 723 places across Hampshire fall within our area, Boldre among them. There’s a separate page for Southampton, roughly 12 miles from Boldre.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Jobs in and around smaller places like Boldre are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand

How the job changes by surface

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.

Risers and ceiling voids

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

What happens if it’s left?

Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Older rural buildings around Boldre move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Why us?

  • Constructionline member
  • CHAS accredited contractor
  • Sealing commercial buildings since 2005
  • Work carried out by CSCS-carded applicators

Take a look at our cost guide and our accreditations.

What affects the price in Boldre

To price the job, we consider:

  • Phasing around occupants
  • Distance, for remote addresses
  • The total length or number of joints
  • Backing rod, priming and other preparation

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

What we need to price the job

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

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • The postcode of the building

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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 usually costs more in the end than doing them right.
