Fire rated sealant in Hatfield Hyde
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Typical jobs include gaps filled with a product that isn’t fire-rated and fire seals that have cracked with movement, across flats & HMOs, linear gaps and door frames.
For a pub, café, guest house or shop in or near Hatfield Hyde, its washrooms and kitchen need the same sealant care as any big building.
All our work is covered by a one-year guarantee, wherever you are in Hertfordshire.

Common questions in Hatfield Hyde
Do you cover Hatfield Hyde for fire rated sealant?
Yes. We work across London and the South East, and Hatfield Hyde is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can you help a landlord with a rental near Welwyn Garden City station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you take on fire stopping in schools and offices?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use, with access planned around residents or staff. Early starts or out-of-hours work can be arranged.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check risers, ceiling voids and cupboards during building checks
- Store the list of sealed gaps with your building paperwork
- Ask every contractor to reseal any fire stopping they disturb
- Check whether a sealant can be painted before decorating over it
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
What fire rated sealant looks like in Hatfield Hyde
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details. Welwyn Garden City, which Hatfield Hyde is part of, was laid out as a garden city in the early twentieth century. Alongside its homes, it has offices, shops, schools and workplaces, each with washrooms, kitchens and fire-rated joints to keep in order.
Managing a site like Creswick Primary & Nursery School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Welwyn Garden City station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

The process
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a handful of gaps, and longer for a whole building, depending on the amount of work. Parking around Hatfield Hyde is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Tell us about any water getting in

Advice
How the job changes by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.
Do you need fire rated sealant in Hatfield Hyde?
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
Signs it’s time to call us include:
- Unsealed gaps around fire door frames
- Damaged fire sealant left by other trades
- Gaps where walls meet ceilings or slabs
- Joints picked up in a fire-stopping survey
If you look after a church, hall or community building such as St Mary Magdalene Church, service openings in its walls need the right fire-rated sealant, as in any building.
What your quote should include
- Which sealant they’ll use, and why
- How long to leave it before use
- What insurance they hold
- Whether they seal over old material or remove it
What affects the cost of fire rated sealant

- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Working hours on commercial sites
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Photos by email, if that is easy
