Smallford Fire Rated Sealant
Fire-stopping gaps in Smallford need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Unsealed gaps where pipes and cables go through a wall
- Standard silicone or caulk in a fire-stopping gap
- Fire stopping disturbed by later work
About our fire rated sealant in Smallford
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you have open joints along the top of partitions and unsealed gaps where pipes and cables go through a wall, we can put it right.
For holiday lets, converted business premises or a community building near Smallford, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Whatever the size of the job, it’s backed by our 12-month guarantee in Smallford and across Hertfordshire.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Big openings where sealant alone is not the tested solution
- Doors that are not fire doors in the first place
- Certifying a building or signing off its fire safety
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
- Linear gaps
- Door frames
- Flats & HMOs
What fire rated sealant looks like in Smallford
Hatfield, which Smallford is part of, is one of England’s post-war new towns. Like the other new towns, Hatfield was planned with its own areas for industry and business, so there are offices, units and workplaces not far from home. Each has washrooms, kitchens and fire-rated joints to keep in order. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a building such as Nicholas Breakspear Catholic School, fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of St Mark, gaps around pipes and cables are worth checking after any building work there.
Smallford is about 2 miles west of Hatfield, in Hertfordshire. Smallford gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Smallford is one of 381 places in Hertfordshire where we work. For nearby work, see our London page.
Work in AL4 works the same way as everywhere else we cover. Whether your property is on Jove Gardens, Lawrence Close and Oaklands Lane or a nearby road, we can help.

Smallford’s nearest station is Hatfield station, about 2.4 miles east of the centre. Nearby you will also find Hill End Hospital (1.4 miles south-west) and The Bunker at Hatfield Police Station (1.5 miles north-east). The countryside around Smallford includes Verulamium Lake and Colney Heath Local Nature Reserve.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Never patch a fire seal with standard sealant
- Tell trades working in the building that fire seals must be put back
- Allow for resealing whenever new services are run
- Keep pictures of seals that will be hidden
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Smallford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

Questions from Smallford
Can you help a landlord with a rental near Hatfield station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Is Smallford in your area for fire rated sealant?
Yes, Smallford is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
How long does fire rated sealant take?
That depends on the amount of work, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We’ll give you a better idea when we quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Signs you need fire rated sealant in Smallford
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
These are the problems we’re asked about most:
- Old fire sealant that has split or come away
- Gaps where walls meet ceilings or slabs
- Open gaps behind door architraves
- Gaps flagged on a fire risk assessment
Letting a property close to Hatfield station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What the job involves on each surface
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Why act early in Smallford
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like Smallford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
