Questions about Twydall
Can you work at a site such as Beechings Way Industrial Centre, by Twydall?
Yes. Our area takes in Twydall and its surroundings, with estates and business parks such as Beechings Way Industrial Centre included. Send details of the unit and the work through our quote form for a quick quote.
Could you schedule work at a campus like University of Greenwich - Medway for the vacation?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will you write the fire-stopping specification?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
What does an EI 60 rating mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Fire stopping in Twydall, done properly
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. The enquiries we see most involve improvised or mixed-product fire seals and fire sealant pulled out of the opening, across small duct penetrations where the tested detail allows, cable penetrations and service gaps in risers. One point of contact handles commercial sealant work in Twydall from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Buildings in a smaller place such as Twydall 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Several jobs near Twydall can be grouped on one trip. Tell us your site hours and we will plan around them.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Have the specification and drawings to hand
- Arrange parking or a loading space
- Make sure the joints can be reached

Cost factors for service penetrations
Quotes vary with the job. It mainly depends on:
- Joint width, depth and condition
- Location, for remote and island sites
- Whether old sealant has to be cut out first
- Working within restricted access windows
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Photos of the joints, close up and from further back
- Whether the building will be occupied during the work
- Your programme or deadline
- The asbestos register, for older buildings
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or use the quote form with what you know.
Owners, agents and contractors
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Twydall. Several sites can go on one quote, which keeps the paperwork simple.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Penetration seals near Twydall
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 31 miles from central London, Twydall is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
For a unit at a site such as Beechings Way Industrial Centre, 0.6 miles to the north-west of Twydall, new power or data runs between office and warehouse can breach a compartment wall. Residences at universities like University of Greenwich - Medway (2.6 miles north-west of Twydall) have compartment walls that must be resealed whenever services change. Large healthcare estates like Medway Maritime Hospital (1.9 miles west of Twydall) change their services often, so penetration seals are worth checking after M&E work.

How the job changes by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.
After the work
A few simple habits keep the new joints working:
- Get seals inspected before ceilings and boxing close
- Check risers and ceiling voids after each round of works
- Report damaged or disturbed seals as soon as they’re spotted
- Don’t let anyone top up a fire seal with the wrong product
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
