Fire rated sealant in Ayres End, done properly
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. Typical jobs include sealant items on a fire risk assessment action list and unsealed gaps where pipes and cables go through a wall, across pipe & cable gaps, service penetrations and flats & HMOs.
Somewhere as small as Ayres End, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Ayres End: your questions answered
Is Ayres End within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Harpenden station?
Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Can you tell me which gaps need fire stopping?
No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

What fire rated sealant looks like in Ayres End
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 work to the specification you’re given, installing the product to its tested details.
Managing a site like The Grove Infant and Nursery School? Then fire-stopping around service openings should be restored whenever new services go in. Community buildings like Parish Church of Saint John the Baptist are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What affects the quote in Ayres End
You’ll get a clear quote before we start. It takes into account:
- Whether the work is at height
- When we can work, for business premises
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What we need to know
To make quoting easier, let us know:
- How we’d reach the joints
- Roughly how big the job is
- The problem you’ve noticed
- Whether it’s a home or a business
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.
Leave it or put it right?
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. In a small place like Ayres End, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

When to call us in Ayres End
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
Common reasons people contact us are:
- Ordinary sealant used where a fire-rated product was needed
- Damaged fire sealant left by other trades
- Linear gaps at the head of walls
- Cracked or shrunken fire-rated sealant
Letting a property close to Harpenden station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
What your quote should include
- Are they insured?
- How long to leave it before use
- Whether all the old sealant comes out first
- What preparation is included
Looking after it afterwards
Aftercare is simple:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- 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
- Keep photos of seals that will be hidden
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Assessing a building’s fire safety
- Walls or floors that weren’t built to resist fire
- Issuing a fire rating or certificate for a building
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
