Where services cross fire walls in Otham
A 2-mile radius around Otham takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Central London is about 33 miles from Otham. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Industrial units on estates such as Park Wood Trading Estate, 0.5 miles to the south of Otham, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. At a university such as University for the Creative Arts (3.4 miles north-west of Otham), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Otham is about 2 miles south-east of Maidstone, in Kent. Businesses, contractors and managing agents in Otham use us for work on service penetrations. Otham is one of 931 places in Kent on our list. For work in that direction, see our London page (33 miles or so).

Fire stopping in Otham
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Otham. If you are dealing with hidden openings found during inspections and seals disturbed by maintenance and left open, we can put it right. Looking for mastic applicators who cover Otham? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Buildings in a smaller place such as Otham that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. For a site in Otham, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open
- Tell staff and tenants when we will be in

Common questions from Otham clients
Do you seal service penetrations in hotels around Otham?
Yes. We install fire-rated and intumescent sealant where it is specified. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.
What happens to BS 476 references for fire stopping in Otham?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is colour matching possible?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Is Otham in your area?
Yes. Sites across Otham are covered, with one number for every area we cover.
What will the job cost?
Every job gets its own fixed quote. To get one, phone 01277 525 020 or email us.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Signing off or certifying a building’s fire stopping
- Openings that need collars, wraps, batts or boards rather than sealant
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly.
Surfaces we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
- Small duct penetrations where the tested detail allows
Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Ask the designer to confirm details early on refits
- Keep general-purpose fillers away from compartment walls
- Keep product data and details in the fire safety file
- Ask which product is in place before decorating
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
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.
Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Why act early in Otham
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we’re called out for in Otham
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 opening isn’t always resealed.
Site and facilities staff are often the first to spot these:
- Hidden openings found during inspections
- Old intumescent sealant that has split away
- Seals that don’t match their tested detail
- Unsealed openings around new pipes and cables
Wherever services are added at a hospital such as KIMS Hospital (to the north of Otham) the compartment line has to be made good with the specified product.
What your quote should include
- How joint depth will be controlled
- What level of public liability insurance do they hold?
- Will failed sealant be removed rather than covered?
- How long is the guarantee, and what does it include?
