FAQs: Blean

Will you work in a care home in Blean without moving residents out?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.

Do you take on work at healthcare sites like Eastbridge Hospital of St Thomas the Martyr?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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.

What do you charge?

Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or send details through our quote form.

What does an EI 60 rating mean?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you approve fire stopping for building control?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail.

How we handle fire stopping in Blean

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and builders’ foam or ordinary silicone in compartment walls, across service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads. Facilities teams, main contractors and managing agents in Blean tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural conversions around Blean can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Common problems we fix in Blean

Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

It’s worth sending us details if you spot any of the following:

  • Service penetrations left open after M&E works
  • Non-fire-rated filler around services
  • Improvised or mixed-product fire seals
  • Fire seals cut back for extra cables and never reinstated

For an estates team at a campus like University of Kent, which lies south-east of Blean, summer M&E works are typically followed by a round of penetration sealing.

Choosing a commercial sealant contractor

Different surfaces, different methods

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter, so we check before sealing.

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.

Compartment walls and floors in Blean

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Blean has two care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal.

For a unit at a centre such as Whitefriars Shopping Centre, which lies south-east of Blean, penetration seals are worth checking after each shop fit. Tenant changes at parks like John Roberts Business Park, 1.1 miles north-west of Blean, bring new data and services, and openings through fire-resisting walls need the specified seal.

Blean is about 3 miles north-west of Canterbury, in Kent. We send applicators to Blean for service penetrations. We work across 931 places in Kent. London is covered too, around 51 miles from Blean.

Building owners, agents and FMs in Blean

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Blean. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Gaps in walls that were never built as compartment walls
  • Fire risk assessments, a job for a competent assessor

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Joints and surfaces we work on

  • Pipe penetrations
  • Linear gaps at wall heads
  • Service gaps in risers
  • Joints between fire-resisting walls and floors
  • Small duct penetrations where the tested detail allows
  • Cable penetrations

On site: what to expect

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Blean are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Move anything stored against the joints
  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs

Advice

Why deal with it now?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these. Converted and older buildings near places like Blean tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
