How we handle fire stopping in Bridgemary
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. Site teams most often ask us about damaged fire seals in risers and voids and seals that don’t match their tested detail, on service gaps in risers, linear gaps at wall heads and pipe penetrations. A specialist sealant contractor works differently from a general builder: on jobs in Bridgemary, preparation and product choice get the time they need.
Buildings in a smaller place such as Bridgemary that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Arrange inspection before areas are covered up
- Check with the data sheet before painting over fire sealant
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
When to call us in Bridgemary
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
It’s worth sending us details if you spot any of the following:
- Seals that don’t match their tested detail
- Snag lists that include open service penetrations
- Expanding foam used as fire stopping
- Fire sealant pulled out of the opening
For a building such as St Matthew's, new heating or data runs are the usual reason penetrations need sealing.

What else we do in Bridgemary
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If neighbouring businesses or buildings around Bridgemary need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings
- Let building users know which areas are affected
Getting a fixed quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

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.

Why it’s worth doing now in Bridgemary
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. In a smaller place such as Bridgemary, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Your questions answered
Would you work within a site like Gosport War Memorial Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is a smaller place like Bridgemary outside your area?
Not at all. Bridgemary is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What do BS EN 1366-3 and BS EN 13501-2 mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Will you write the fire-stopping specification?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.
Are you members of a third-party fire-stopping installer scheme?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we’ll say so right away rather than waste your time.
