Adgestone: questions and answers
What does the BS 476 change mean for fire-rated sealant in Adgestone?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you seal service penetrations in hotels around Adgestone?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Can staff carry on working while you’re here?
Typically, yes. Phased work can be planned so areas stay in use.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Fire stopping in Adgestone
A fire-rated sealant is only one part of a tested system: 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. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and the usual reasons a site gets in touch are hidden openings found during inspections and open linear gaps along the top of fire-resisting walls. Most enquiries from Adgestone start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Barn and farm-building conversions near places like Adgestone 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.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What else we do in Adgestone
Different surfaces, different methods
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
Keeping the joints sound
After handover, a little attention goes a long way:
- Include service cupboards in routine inspections
- Check with the data sheet before painting over fire sealant
- Report damaged or disturbed seals as soon as they’re spotted
- Make fire stopping part of every scope that crosses a fire-resisting wall
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
Leave it or put it right?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. Around Adgestone, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Adgestone can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
Getting the site ready
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we will be in
- Arrange parking or a loading space

Fire stopping in Adgestone: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail. A 2-mile radius around Adgestone takes in a good number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.
In a school such as Brading Church of England Controlled Primary School, fire-rated sealant goes in around service penetrations where it is specified. For a hotel such as Chaston Manor Hotel, 1 mile to the south of Adgestone, penetration seals are worth checking after any refit or services upgrade.

When to call us in Adgestone
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Site and facilities staff are often the first to spot these:
- Hidden openings found during inspections
- Unsealed joints where partitions meet the slab
- Penetration schedules that need working through
- Old intumescent sealant that has split away
Older community buildings such as Church of St. John the Evangelist that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
