How we handle fire rated sealant in Penshurst
We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you are dealing with cracked or shrunken fire-rated sealant and gaps left after a refit or conversion, we can put it right.
In a village or hamlet like Penshurst, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check whether a sealant can be painted before decorating over it
- Flag any open gap you spot round a pipe or cable
- Ask every contractor to reseal any fire stopping they disturb
- Check risers, ceiling voids and cupboards during building checks
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t and we will tell you which one you have.
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.
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Penshurst, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Signs you need fire rated sealant in Penshurst
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
The most common problems we see are:
- Old fire sealant that has split or come away
- Standard silicone or caulk in a fire-stopping gap
- Unsealed gaps where pipes and cables go through a wall
- Gaps where walls meet ceilings or slabs
Rented homes near Penshurst station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How the job changes by surface
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before applying the sealant.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.
Fire rated sealant in Penshurst: local notes
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like Church of St John the Baptist are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as Penshurst Church of England Voluntary Aided Primary School, fire-stopping around service openings should be restored whenever new services go in.

Why deal with it now?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that does not depend on other work. Around Penshurst, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

When it isn’t the sealant
A few problems are outside what sealant work can do:
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
- Problems with the door itself rather than the gap around the frame
