About our fire rated sealant in Nettleden
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, one gap at a time. If you’re dealing with joints picked up in a fire-stopping survey and fire seals that have cracked with movement, we can put it right.
For a small place like Nettleden, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
Our work is backed for twelve months.

Surface by surface
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins so residents know what to expect.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Workplaces and buildings in Nettleden
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 are given, installing the product to its tested details.
Letting a property close to Berkhamsted station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Great Gaddesden Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

What else we do in Nettleden
Common problems we fix in Nettleden
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
The problems people generally mention when they call include:
- Door frames with gaps between frame and wall
- Damaged fire sealant left by other trades
- Linear gaps at the head of walls
- Standard silicone or caulk in a fire-stopping gap
If you look after a church, hall or community building such as Church of St Lawrence, service openings in its walls need the right fire-rated sealant, as in any building.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Nettleden questions
Do you cover Nettleden for fire rated sealant?
Yes, Nettleden is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
I let a flat near Berkhamsted station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, large or small.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you carry out fire risk assessments?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Flag any open gap you spot round a pipe or cable
- Do not paint over fire sealant until it has cured
- Store the list of sealed gaps with your building paperwork
- Ask every contractor to reseal any fire stopping they disturb
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we’ll tell you which one you have.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Leave it or put it right?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Where a wall is exposed, as many are in small places like Nettleden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
