Where services cross fire walls in St Mary Hoo
St Mary Hoo is about 30 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. Campus buildings at universities such as University of Greenwich - Medway, 4.9 miles to the south-west of St Mary Hoo, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
St Mary Hoo is about 4 miles south of Canvey Island, in Medway. Commercial clients in St Mary Hoo can call on us for service penetrations, as part of our coverage of Medway. Across Medway, 54 places are covered, St Mary Hoo among them. London is covered too, some 30 miles away.

Signs you need fire stopping in St Mary Hoo
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
Most enquiries start with one or more of the following:
- Unsealed openings around new pipes and cables
- Head-of-wall gaps with no fire seal
- Fire seals cut back for extra cables and never reinstated
- Fire-stopping items raised at inspection or handover
On a hospital site such as Medway Maritime Hospital, 6 miles south-west of St Mary Hoo, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Questions to ask before you book
- Their public liability cover
- Their plan for phasing and protecting the area
- How they handle RAMS and site documents
- What the guarantee covers, and for how long
Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. For a building around St Mary Hoo, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Point out any areas we must not close
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work

Related advice
Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these. Around St Mary Hoo, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

St Mary Hoo: questions and answers
What does the BS 476 change mean for fire-rated sealant in St Mary Hoo?
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.
Could you schedule work at a campus like University of Greenwich - Medway for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
What we seal
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
What affects the price in St Mary Hoo
There’s no standard rate for sealant work, because every site is different. What we take into account:
- How much there is to seal
- Distance, for remote addresses
- The site’s rules and procedures
- Backing rod, priming and other preparation
Small jobs and large programmes are priced from the same things: 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.
What we need to price the job
We can often quote from photos and a few details. It helps to include:
- The site address and postcode
- Anything awkward about access or site hours
- The product your specification calls for
- Approximate linear metres or a joint schedule
