Pirton Fire Rated Sealant
Problem with your fire-stopping gaps in Pirton? We cut out the old, prepare the joints and apply the right sealant.
- Damaged fire sealant left by other trades
- Holes left by a change of layout
- Unsealed gaps where pipes and cables go through a wall
What the job involves on each surface
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service against the product’s tested range.
About our fire rated sealant in Pirton
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on pipe & cable gaps, door frames and plasterboard & masonry, and the jobs we see most are door frames with gaps between frame and wall and old fire sealant that has split or come away.
If you have holiday lets, a converted barn used for business or a community building near Pirton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Our work is backed for twelve months, in Pirton and everywhere else we cover.

Fire rated sealant in Pirton: 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, 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 Church of St Mary (Church of England), gaps around pipes and cables are worth checking after any building work there. If you look after a building such as Pirton School, service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Hitchin station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Pirton is about 3 miles north-west of Hitchin, in Hertfordshire. Pirton gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. 381 places in Hertfordshire are on our list, large and small.

How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a small place like Pirton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

When something else is needed
To be straight with you, some problems need a different trade:
- Big openings where sealant alone isn’t the tested solution
- Problems with the door itself rather than the gap around the frame
- Deciding what fire stopping a building needs
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Door frames
- Flats & HMOs
- Service penetrations
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry
Why act early in Pirton
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that doesn’t depend on other work. Where a wall is exposed, as many are in small places like Pirton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.

How we quote for fire rated sealant
For a quick quote, just ask. What matters most is:
- Any working-time requirements on site
- The size of the job
- The type of sealant required
- The old material and how stubborn it is
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Whether it’s a home or a business
- What’s wrong with the joints now
- The rough size of the job
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Include fire stopping when you schedule refits
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Store the list of sealed gaps with your building paperwork
- Do not paint over fire sealant until it has cured
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.
