Fire rated sealant in Mundaydean Bottom, done properly

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you’re dealing with cracked or shrunken fire-rated sealant and gaps filled with a product that isn’t fire-rated, we can help, whatever the surface.

Somewhere as small as Mundaydean Bottom, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

All our work is covered by our one-year guarantee.

What happens if it’s left?

Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we’ll tell you. Older cottages and farmhouses around Mundaydean Bottom can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Common problems we fix in Mundaydean Bottom

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.

Most people get in touch after spotting one of these:

  • Open gaps behind door architraves
  • Gaps left after a refit or conversion
  • Ordinary sealant used where a fire-rated product was needed
  • Open joints along the top of partitions

If you look after a building such as Burford School, fire-stopping around service openings should be restored whenever new services go in.

Our hiring checklist

Surface by surface

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. Somewhere like Mundaydean Bottom needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions
  • For business premises, tell us about site rules or sign-in

What affects the cost of fire rated sealant

Jobs vary more than people expect. The main factors:

  • Any mould that needs treating
  • Whether the work is at height
  • The size of the job
  • Whether old sealant or filler has to be cut out

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

What we need to know

Photos help, but a description is a good start. Please mention:

  • The address or postcode of the job
  • How many joints, rooms or windows are involved
  • The problem you’ve noticed
  • Any previous sealing or DIY work

We quote each job on its own. Just call 0345 464 0079 or drop us an email with the details, and photos are welcome.

Should I try it myself first?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
