How we handle fire stopping in Blackmore
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to 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. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers, and what we are called in for most is fire seals cut back for extra cables and never reinstated and old intumescent sealant that has split away. A specialist sealant contractor works differently from a general builder: on jobs in Blackmore, preparation and product choice get the time they need.
Around smaller places like Blackmore, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. 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 we explain exactly what that covers when we quote.

Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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.

Compartment walls and floors in Blackmore
Fire stopping of openings and penetrations in England falls under 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. Our part stays the same: the specified product, installed to its tested detail. At about 22 miles from central London, Blackmore is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Older community buildings such as Church of St Laurence that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a school such as Blackmore Primary School, penetration sealing fits best at the end of the summer works.

Owners, agents and contractors
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
On site: what to expect
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Blackmore may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
Before we start on site
- Tell us which areas need to stay in use
- Share your working hours and any access restrictions
- Arrange parking or a loading space

When to call us in Blackmore
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Typical triggers for a call:
- Improvised or mixed-product fire seals
- Fire-stopping items raised at inspection or handover
- Non-fire-rated filler around services
- Unsealed openings around new pipes and cables
Residences at universities like Writtle University College Cow Watering Campus (to the north-east of Blackmore) have compartment walls that must be resealed whenever services change.
What to look for in a quote
- Who will actually carry out the work
- How joint depth will be controlled
- The named product and why it was chosen
- Proof of insurance

What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Approving the work on behalf of building control
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Fire doors, dampers or other fire safety equipment
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
How the quote is worked out
What shapes the price:
- Joint width, depth and condition
- The product specified
- Whether old sealant has to be cut out first
- Location, for remote and island sites
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
- Any specification or named product
- Asbestos survey details if the building is older
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 a schedule or drawings.
