Common questions from Bentley Heath clients
Is Bentley Heath too small for you to travel to?
No. Places such as Bentley Heath are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you take on work at estates like Wrotham Business Park, close to Bentley Heath?
Yes. Estates, retail parks and business parks around Bentley Heath, Wrotham Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. New services after M&E works often breach existing seals and we close them with the specified product.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
What do you charge?
Every job gets its own fixed quote. For yours, ring 01277 525 020 or email us with a description of the work.
About our fire stopping in Bentley Heath
Facilities managers in Bentley Heath often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you’re dealing with fire sealant pulled out of the opening and builders’ foam or ordinary silicone in compartment walls, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bentley Heath it comes down to the same thing: the right product in a properly prepared joint.
Rural conversions around Bentley Heath can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Common problems we fix in Bentley Heath
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.
Any of the following is a good reason to get the joints checked over:
- Non-fire-rated filler around services
- Old intumescent sealant that has split away
- Improvised or mixed-product fire seals
- Service penetrations left open after M&E works
Tenant changes at parks like Wrotham Business Park, 0.8 miles south of Bentley Heath, bring new data and services, and openings through fire-resisting walls need the specified seal.
Questions to ask before you book
- Will RAMS and insurance details be available?
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid

Advice
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Plastic pipes whose detail calls for a collar or wrap
- Issuing fire ratings or certificates for seals
- Reviewing a building’s overall fire safety
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly.
Surfaces we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Check with the data sheet before painting over fire sealant
- Have penetrations checked while they can still be seen
- Agree the fire-stopping specification before services go in
- Include service cupboards in routine inspections
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
