Fire rated sealant in Astrope
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you’re dealing with joints picked up in a fire-stopping survey and gaps around pipes and cables through fire-resisting walls, we can put it right, whatever the surface.
For a small place like Astrope, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Fire rated sealant around Astrope
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.
Rented homes near Cheddington station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Long Marston VA Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.
Astrope is about 5 miles east of Aylesbury, in Hertfordshire. From the centre of Astrope to the outskirts, fire rated sealant is available for homes and businesses alike, from flats and houses to offices and hotels. Our area takes in 381 places across Hertfordshire, large and small. Oxford is on our list too, around 23 miles away.
We work across the HP23 postcode area for fire rated sealant and the streets around it. We also cover Puttenham (1 mile west), Long Marston (1 mile north), Buckland (2 miles south), Aston Clinton (2 miles south-west) and Broughton (3 miles west).

Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Looking after it afterwards
Looking after new joints is easy:
- Keep pictures of seals that will be hidden
- Plan fire stopping into any work that goes through walls or floors
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Walls or floors that weren’t built to resist fire
- Assessing a building’s fire safety
- Certifying a building or signing off its fire safety
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on
- Linear gaps
- Door frames
- Plasterboard & masonry
- Pipe & cable gaps
- Flats & HMOs
- Service penetrations
When to call us in Astrope
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
It’s worth asking for a quote if you see:
- Unsealed gaps where pipes and cables go through a wall
- Door frames with gaps between frame and wall
- Fire seals that have cracked with movement
- Ordinary sealant used where a fire-rated product was needed
Community buildings like Church of St Mary (Church of England) are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

- Are they insured?
What affects the quote in Astrope
Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Working hours on commercial sites
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Advice
Astrope questions
Do you cover smaller places like Astrope?
Yes, Astrope is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do fire rated sealant in Astrope?
Yes, Astrope is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
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 fitted to the maker’s details.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
