Fire rated sealant in Shenleybury
Deciding which gaps need fire stopping isn’t our role; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We work on door frames, flats & HMOs and plasterboard & masonry, and people most often call us about sealant items on a fire risk assessment action list and ordinary sealant used where a fire-rated product was needed.
If you have holiday lets, a converted barn used for business or a community building near Shenleybury, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Fire rated sealant in Shenleybury: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 church, hall or community building such as St Botolphs, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Clore Shalom School, fire-stopping around service openings should be restored whenever new services go in.

Why it’s worth doing now in Shenleybury
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Shenleybury, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

If the job is outside, mention outbuildings, exposed walls and how to reach them.

What else we do in Shenleybury
What we are called out for in Shenleybury
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Most people get in touch after spotting one of these:
- Open joints along the top of partitions
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
- Cracked or shrunken fire-rated sealant
For landlords with property near Radlett station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

FAQs for Shenleybury
Is Shenleybury within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Shenleybury in your area for fire rated sealant?
Yes, Shenleybury 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.
Do you take on fire stopping in schools and offices?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.
Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used.
Do you certify the fire stopping?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.
How long does fire rated sealant take?
A typical job takes a few hours for a handful of gaps, and longer for a whole building. We’ll confirm how long when we quote.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
What the job involves on each surface
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep pictures of seals that will be hidden
- Allow for resealing whenever new services are run
- Look in service cupboards and ceiling voids from time to time
- Ask every contractor to reseal any fire stopping they disturb
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record.
