Fire stopping near Old Wives Lees

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Signs you need fire stopping in Old Wives Lees

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

Look out for the following:

  • Unsealed penetrations discovered above suspended ceilings
  • Fire stopping installed outside its tested range
  • Head-of-wall gaps with no fire seal
  • Unsealed openings around new pipes and cables

At a university such as University of Kent, which lies north-east of Old Wives Lees, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

What your quote should include

  • Is the sealant right for the movement and the substrate?
  • Their plan for phasing and protecting the area
  • Their public liability cover
  • Who will actually carry out the work

How to choose a sealant contractor

Fire stopping in Old Wives Lees

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have non-fire-rated filler around services and fire stopping installed outside its tested range, we can help, whatever the surface. Most enquiries from Old Wives Lees start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For a smaller site near Old Wives Lees, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Questions we are asked in Old Wives Lees

Can you take on a job at a hospital such as 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.

What does the BS 476 change mean for fire-rated sealant in Old Wives Lees?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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 colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For a building around Old Wives Lees, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements
  • Send your site hours and access windows

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Record which product was used where
  • Flag new cables with no seal around them
  • Leave fire sealant to cure fully before covering it
  • Settle who seals which penetrations at the start of a project

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.

Compartment walls and floors in Old Wives Lees

In England, Approved Document B covers fire stopping of 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. Our part stays the same: the specified product, installed to its tested detail. Old Wives Lees lies roughly 49 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. Where a unit on an estate such as CMA Industrial Park, which lies north-east of Old Wives Lees, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Old Wives Lees is about 5 miles west of Canterbury, in Kent. If you are looking for fire stopping in Old Wives Lees, we can help. 931 places across Kent fall within our area, including Old Wives Lees. We also cover London, around 49 miles from Old Wives Lees.

Work for main contractors and building owners

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.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Writing the fire-stopping specification
  • Issuing fire ratings or certificates for seals
  • Reviewing a building’s overall fire safety

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
