How we handle fire stopping in Itchen Stoke
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. 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 unsealed joints where partitions meet the slab and damaged fire seals in risers and voids. For commercial sealant work in Itchen Stoke, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like Itchen Stoke 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.
A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, call the office on 01277 525 020 or email the details over and we will arrange a return visit.

Common problems we fix in Itchen Stoke
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 the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Look out for the following:
- Service penetrations left open after M&E works
- Fire seals cut back for extra cables and never reinstated
- Builders’ foam or ordinary silicone in compartment walls
- Improvised or mixed-product fire seals
For a building such as St Mary's Church, new heating or data runs are the usual reason penetrations need sealing.

What affects the price in Itchen Stoke
Quotes vary with the job. It mainly depends on:
- Any access equipment needed
- Working within restricted access windows
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
A few photos plus some basic facts will normally do. It helps to include:
- A wide shot and a close-up of the area
- When you need the work done
- Access details, including height
- The type of building and who uses it
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email the details over.
Itchen Stoke: questions and answers
Is a hospital such as St John's Rooms And Chapel somewhere you can work?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens to BS 476 references for fire stopping in Itchen Stoke?
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.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Keeping the joints sound
For the best life from the joints:
- Put resealing into every M&E and fit-out package
- File the specified details where the next contractor can find them
- Ask the designer to confirm details early on refits
- Report damaged or disturbed seals as soon as they’re spotted
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same 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.

Approved Document B is the English guidance that covers fire stopping around openings and penetrations.
