Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Rural sites near Botley may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work

How we handle fire stopping in Botley
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations, and the usual reasons a site gets in touch are hidden openings found during inspections and snag lists that include open service penetrations.

Barn and farm-building conversions near places like Botley 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.
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.

Questions about Botley
What happens to BS 476 references for fire stopping in Botley?
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.
Is a smaller place like Botley outside your area?
Not at all. Botley is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is the work guaranteed?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Common problems we fix in Botley
Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
Clients normally get in touch after noticing one or more of the following:
- Damaged fire seals in risers and voids
- Fire-stopping items raised at inspection or handover
- Expanding foam used as fire stopping
- Seals that don’t match their tested detail
Holiday works at schools like Ley Hill School often leave service openings to seal before pupils return.
What your quote should include
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
- Can the work be phased to keep areas open?
- Whether old or failed sealant will be cut out, not overlaid
Why deal with it now?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. One visit to deal with every failing joint makes more sense than several trips to a place like Botley. Photos of every joint help us quote for the whole job.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- File the specified details where the next contractor can find them
- Look above ceilings when tiles are lifted for other jobs
- Check with the data sheet before painting over fire sealant
- Have penetrations checked while they can still be seen
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
Compartments and services around Botley
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. We install whatever has been specified, to the product’s tested detail. Botley lies roughly 25 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
At a healthcare site like Amersham Hospital, which lies south-west of Botley, new services through compartment walls are a constant, and each needs the specified seal. At a university such as Buckinghamshire New University (3.4 miles south-west of Botley), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Surface by surface
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
