How does the move away from BS 476 affect penetration seals in Cop Street?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Fire stopping for commercial buildings in Cop Street
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you’re dealing with fire stopping installed outside its tested range and damaged fire seals in risers and voids, we can put it right. Searching for sealant specialists in Cop Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Barn and farm-building conversions near places like Cop Street 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.
Our workmanship is guaranteed for 12 months, in Cop Street as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Building owners, agents and FMs in Cop Street
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Fire risk assessments, a job for a competent assessor
- Approving the work on behalf of building control
- Deciding what a wall or floor needs, which belongs to the designer
If you are not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Settle who seals which penetrations at the start of a project
- Foam or ordinary sealant is never a fire-seal repair
- Brief every trade that openings they make must be sealed
- Have penetrations checked while they can still be seen
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there, not months later.

General trades versus a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Location, for remote and island sites
- Removal of failed or old sealant
- The total length or number of joints
- Access and working height
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Access details, including height
- The postcode of the building
- Drawings or a marked-up plan, if available
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email us.
Fire-rated sealing for Cop Street buildings
Cop Street is about 61 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a building at a site such as Birnham Farm Business Centre, which lies south of Cop Street, a check of penetration seals after each fit-out is good practice. Hotels such as The Lion Hotel (0.8 miles south of Cop Street) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
