How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Rural sites near Knowle may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Tell staff and tenants when we’ll be in
- Confirm the product named in the specification
- Point out any areas we must not close
Quotes
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Fire stopping for commercial buildings in Knowle
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the usual reasons a site gets in touch are improvised or mixed-product fire seals and damaged fire seals in risers and voids. Most enquiries from Knowle start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as Knowle still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Signs you need fire stopping in Knowle
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
If one of these sounds familiar, it’s time for a closer look:
- Damaged fire seals in risers and voids
- Penetration schedules that need working through
- Unsealed openings around new pipes and cables
- Builders’ foam or ordinary silicone in compartment walls
Hospital estates such as Knowle Hospital (less than half a mile north-east of Knowle) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Questions to ask before you book
- What site paperwork they can supply
- How long is the guarantee, and what does it include?

When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Plastic pipes whose detail calls for a collar or wrap
- Signing off or certifying a building’s fire stopping
- Construction that lacks the fire resistance the seal relies on
If you are not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Report damaged or disturbed seals as soon as they’re spotted
- Arrange inspection before areas are covered up
- Record which product was used where
- Look above ceilings when tiles are lifted for other jobs
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small.
Compartments and services around Knowle
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Knowle is about 64 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
At a college such as Fareham College, 2 miles to the south of Knowle, checking penetration seals after summer M&E works is good practice. In a retail centre such as Broadcut Retail Park (2 miles south-east of Knowle), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

How the job changes by surface
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.
Why act early in Knowle
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. One visit to deal with every failing joint makes more sense than several trips to a place like Knowle. Send photographs of each area and we will quote for the lot.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Questions we are asked in Knowle
Will you plan work around the academic year at somewhere like Fareham College?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you seal around new services in a hotel near Knowle?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
