Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Brief every trade that openings they make must be sealed
  • Foam or ordinary sealant is never a fire-seal repair
  • Include service cupboards in routine inspections
  • Have penetrations checked while they can still be seen

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

Fire stopping in Leverton

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. Site teams most often ask us about head-of-wall gaps with no fire seal and snag lists that include open service penetrations, on pipe penetrations, joints between fire-resisting walls and floors and service gaps in risers. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Leverton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Leverton, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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.

Questions about Leverton

Is a smaller place like Leverton outside your area?

No. Places such as Leverton are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you work at a site such as Charnham Business Park, by Leverton?

Yes. Our area takes in Leverton and its surroundings, with estates and business parks such as Charnham Business Park included. Photos and a short description are enough for a first look.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you tell us what fire stopping our building needs?

No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it.

What does an EI 60 rating mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.

Where we work in Leverton

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

Compartment walls and floors in Leverton

Leverton has a number of hotels close by, all within 2 miles. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. 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. Either way, we install the specified product to its tested detail.

Holiday works at schools like Chilton Foliat Church of England Primary School often leave service openings to seal before pupils return. Hotels such as The Bear Hotel (0.9 miles south-east of Leverton) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

When to call us in Leverton

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position, so it has to come out.

These are often picked up first by site or facilities staff:

  • Fire seals cut back for extra cables and never reinstated
  • Hidden openings found during inspections
  • Penetration schedules that need working through
  • Fire sealant pulled out of the opening

Offices at parks like Charnham Business Park (0.7 miles south-east of Leverton) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Advice

Why act early in Leverton

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Converted and older buildings near places like Leverton tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
