About our fire stopping in Hatfield Hyde
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about head-of-wall gaps with no fire seal and unsealed openings around new pipes and cables, across small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers. A single leaking joint is often how a building in Hatfield Hyde first comes to us: we look at the rest while we’re there and tell you what we find.
Fire-rated sealing in a place like Hatfield Hyde is typically a single building at a time. Send the specification, drawings or photographs of the openings and we will quote to suit.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

From enquiry to sign-off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in Hatfield Hyde, the main thing is a clear picture of the work, so send photos of each area. You’ll then get a fixed price for the work.
- 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.
- 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.
Before we start on site
- Confirm the product named in the specification
- Point out any areas we must not close
- Share the asbestos register for older buildings

Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- File the specified details where the next contractor can find them
- Keep general-purpose fillers away from compartment walls
- Have penetrations checked while they can still be seen
- Check risers and ceiling voids after each round of works
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Other services in Hatfield Hyde
Do you need fire stopping in Hatfield Hyde?
Openings in fire-resisting walls normally appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
Site and facilities staff are often the first to spot these:
- Service penetrations left open after M&E works
- Penetration schedules that need working through
- Unsealed joints where partitions meet the slab
- Fire-rated sealant that has cracked or shrunk back
For a site team at a college like Oaklands College - Welwyn Garden City Campus, 1.6 miles north of Hatfield Hyde, fire-rated sealing is best scheduled after the summer works.

Your questions answered
Can you work on a hospital site such as Queen Elizabeth II Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Hatfield Hyde off your patch?
Not at all. Hatfield Hyde is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Is fire stopping in Scotland covered by different guidance?
Scotland sets its own building regulations, with Technical Handbooks. Either way, we install the specified sealant to its tested detail.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see and we close them with the specified product.
Do you design or specify fire stopping?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Plastic pipes whose detail calls for a collar or wrap
- Deciding what a wall or floor needs, which belongs to the designer
- Reviewing a building’s overall fire safety
Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly before you book.
What we seal
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
Compartments and services around Hatfield Hyde
Hatfield Hyde is part of, or right next to, Welwyn Garden City, which was built as a planned town. Decades of new cabling and pipework in planned-town buildings can leave openings in compartment walls to seal with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
In a retail centre such as Howard Centre (1.3 miles north of Hatfield Hyde), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. On estates like Little Ridge Industrial Estate (1.1 miles north-east of Hatfield Hyde), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
