How we handle fire stopping in The Flints
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and what we’re called in for most is fire-stopping items raised at inspection or handover and open linear gaps along the top of fire-resisting walls. Facilities teams, main contractors and managing agents in The Flints tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like The Flints often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Do you need fire stopping in The Flints?
Plenty of openings were simply never closed. They come to light during inspections, refits or when another trade lifts a tile.
It’s worth sending us details if you spot any of the following:
- Unsealed joints where partitions meet the slab
- Openings found when ceilings come down for a refit
- Fire sealant pulled out of the opening
- Service penetrations left open after M&E works
In a building such as Church of St Mary Magdalene, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Questions to ask before you book
- Their pre-qualification and accreditations
- How they handle RAMS and site documents
- How the existing material will be dealt with
- What level of public liability insurance do they hold?
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- File the specified details where the next contractor can find them
- Foam or ordinary sealant is never a fire-seal repair
- Ask which product is in place before decorating
- Arrange inspection before areas are covered up
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way unless the designer specifies otherwise.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
On site: what to expect
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a building around The Flints, 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.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we will need
- Tell us which areas need to stay in use

Advice
What affects the price in The Flints
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- The site’s rules and procedures
- Removal of failed or old sealant
- Access and working height
- Quantities, in metres or numbers
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Questions about The Flints
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in The Flints?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Does your area include sites such as Butterfield Business Park, near The Flints?
Yes. Estates, retail parks and business parks around The Flints, Butterfield Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
What do you charge?
Every job gets its own fixed quote. For yours, call 01277 525 020 or email a schedule or drawings with a description of the work.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you cover The Flints?
Yes. We take on work across The Flints, and the same phone number covers every area.

Other services in The Flints
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

The Flints lies roughly 32 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations.
