Fire rated sealant in Potters Bar
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. Typical jobs include linear gaps at the head of walls and seals cut through by electricians, plumbers or data installers, across plasterboard & masonry, pipe & cable gaps and door frames.
In a town like Potters Bar, commercial work can mean offices, shops, schools, surgeries or small business units. All of them have washroom and kitchen joints, and many have fire-rated joints around pipes and cables.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Do not paint over fire sealant until it has cured
- Check risers, ceiling voids and cupboards during building checks
- File the fire-stopping record where your assessor can find it
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded.
