Your questions answered
Do you take on work at healthcare sites like Bexhill Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
What happens to BS 476 references for fire stopping in Watermill?
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.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Fire stopping in Watermill
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you are dealing with head-of-wall gaps with no fire seal and seals that don’t match their tested detail, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Watermill, preparation and product choice get the time they need.
Smaller places such as Watermill still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What else we do in Watermill
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Watermill, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Share your working hours and any access restrictions
- Arrange parking or a loading space
- Confirm the product named in the specification

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Why deal with it now?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Converted and older buildings near places like Watermill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Fire doors, dampers or other fire safety equipment
- Large openings beyond what any sealant detail covers
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly.
Where we work in Watermill
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Pipe penetrations
Maintenance after handover
Once the work is signed off, these steps help:
- Keep product data and details in the fire safety file
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Check with the data sheet before painting over fire sealant
- Agree the fire-stopping specification before services go in
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.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.
Building owners, agents and FMs in Watermill
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
What we’re called out for in Watermill
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.
Things that typically lead to an enquiry:
- Service penetrations left open after M&E works
- Unsealed penetrations discovered above suspended ceilings
- Unsealed joints where partitions meet the slab
- Penetration schedules that need working through
For a site team at a college like Bexhill 6th Form College (2.3 miles south-east of Watermill), fire-rated sealing is best scheduled after the summer works.

Service penetrations in Watermill buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Watermill is about 49 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Hospital estates such as Bexhill Hospital (to the south of Watermill) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Schools such as Bexhill High Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
