Fire rated sealant in Wareside
We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We work on service penetrations, flats & HMOs and linear gaps, and people most often call us about joints picked up in a fire-stopping survey and old fire sealant that has split or come away.
For holiday lets, converted business premises or a community building near Wareside, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Do you have insurance?

Different surfaces, different methods
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for the gap we’re sealing.
What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
- Sign-off of the building, which sits with building control or your assessor
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry
- Door frames
- Flats & HMOs
- Service penetrations
Common problems we fix in Wareside
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
It’s worth asking for a quote if you see:
- Holes left by a change of layout
- Ordinary sealant used where a fire-rated product was needed
- Gaps flagged on a fire risk assessment
- Fire stopping disturbed by later work
Community buildings like Church of the Holy Trinity are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
What to look for in a quote
- What happens if they find a problem under the old sealant
- How much experience the applicator has
- Which colour the sealant will be
- How long to leave it before use
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Fire rated sealant in Wareside: local notes
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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Ware station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Wareside Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Plan fire stopping into any work that goes through walls or floors
- Don’t paint over fire sealant until it has cured
- Flag any open gap you spot round a pipe or cable
- Tell trades working in the building that fire seals must be put back
Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of 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. Get it sealed and recorded.
How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away.

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

- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.

Before we arrive
