After the work
To get the most from the new sealant:
- Ask which product is in place before decorating
- Ask the designer to confirm details early on refits
- Have penetrations checked while they can still be seen
- Look above ceilings when tiles are lifted for other jobs
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
How we handle fire stopping in Hersden
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and cable penetrations, and what we are called in for most is fire-stopping items raised at inspection or handover and seals that don’t match their tested detail. Facilities teams, main contractors and managing agents in Hersden tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Hersden, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why deal with it now?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. For buildings in places like Hersden, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

FAQs: Hersden
Can work at a site such as Canterbury Christ Church University fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hersden?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Hersden need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Getting the site ready
- Send any specification or drawings in advance
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints

Fire stopping in Hersden: the local picture
Central London is about 56 miles from Hersden. Office refits around the commuter belt bring new cabling through fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Holiday works at schools like Hersden Village Primary School often leave service openings to seal before pupils return. Where a unit on an estate such as Canterbury Industrial Park (0.6 miles east of Hersden), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. At a healthcare site like St Martins Hospital, 3.4 miles to the south-west of Hersden, new services through compartment walls are a constant, and each needs the specified seal.

When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire risk assessments, a job for a competent assessor
- Writing the fire-stopping specification
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
