Trusted fire rated sealant in Heaverham

Fire rated sealant in Heaverham, done properly

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We’re often asked to deal with gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap, across pipe & cable gaps, service penetrations and plasterboard & masonry.

If you have holiday lets, a converted barn used for business or a community building near Heaverham, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

A one-year guarantee comes with the work, just as it does everywhere we cover.

When it isn’t the sealant

We’ll always be straight with you, so here’s what sealant cannot fix:

  • A wall that is not a fire-resisting element to begin with
  • Problems with the door itself rather than the gap around the frame
  • Sign-off of the building, which sits with building control or your assessor

If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Joints and surfaces we work on

  • Linear gaps
  • Pipe & cable gaps
  • Flats & HMOs
  • Service penetrations
  • Plasterboard & masonry
  • Door frames

Leave it or put it right?

Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. Where a wall is exposed, as many are in small places like Heaverham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of gaps, and longer for a whole building from start to finish. Somewhere like Heaverham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Let us know about earlier repairs to the joints
  • Keep children and pets away from the work area

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Include fire stopping when you schedule refits
  • Keep the record of products and locations with your fire safety documents
  • Tell trades working in the building that fire seals must be put back
  • Get damaged fire seals looked at promptly

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.

What fire rated sealant looks like in Heaverham

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Kemsing Primary School, service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Kemsing station, any gap left by new services in shared walls should be closed with a fire-rated product.
