Cock Clarks Fire Rated Sealant
Our applicators work in Cock Clarks on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Open holes round services passing through fire walls
- Ordinary sealant used where a fire-rated product was needed
- Fire seals that have cracked with movement
Honest limits
New sealant cannot fix everything, and we’ll tell you before any work starts. It won’t solve:
- Walls or floors that weren’t built to resist fire
- Doors that aren’t fire doors in the first place
- Fire risk assessments, which need a qualified assessor
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

How we handle fire rated sealant in Cock Clarks
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Typical jobs include seals cut through by electricians, plumbers or data installers and gaps around pipes and cables through fire-resisting walls, on pipe & cable gaps, flats & HMOs and linear gaps.
For holiday lets, converted business premises or a community building near Cock Clarks, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
You get a one-year guarantee, the same in Cock Clarks as everywhere else we work.

What the job involves on each surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail and we’ll flag it.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why it’s worth doing now in Cock Clarks
Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Where a wall is exposed, as many are in small places like Cock Clarks, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Workplaces and buildings in Cock Clarks

We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Include hidden areas like risers in routine checks
- File the fire-stopping record where your assessor can find it
- Photograph sealed gaps before they’re covered up
- Ask which product was used before you paint
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.
