Fire rated sealant for homes and businesses in Thundridge
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. We’re often asked to deal with gaps flagged on a fire risk assessment and ordinary sealant used where a fire-rated product was needed, across flats & HMOs, door frames and pipe & cable gaps.
For a small place like Thundridge, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
Every job comes with a one-year guarantee, wherever you are in Hertfordshire.

The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Thundridge, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

Thundridge questions
I let a flat near Ware station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Thundridge?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Will you assess my building’s fire safety?
No. We work from the specification you give us, and apply each product to its tested details.
Where do you work from?
We work from Crawley. We cover Thundridge and the rest of Hertfordshire.
How long does fire rated sealant take?
Most jobs take anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. Your quote will say how long we expect yours to take.
Looking after it afterwards
Looking after new joints is easy:
- Include hidden areas like risers in routine checks
- Keep the record of products and locations with your fire safety documents
- Keep pictures of seals that will be hidden
- Report cracked or damaged seals as soon as you notice them
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so the item can be closed.
What we’re called out for in Thundridge
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
Keep an eye out for any of the following:
- Linear gaps at the head of walls
- Gaps filled with a product that is not fire-rated
- Unsealed gaps around fire door frames
- Old fire sealant that has split or come away
Schools such as Thundridge Church of England Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Surface by surface
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Where a wall is exposed, as many are in small places like Thundridge, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us
- Quality sealants from Arbo and Everbuild
- We never seal over old sealant

Fire rated sealant around Thundridge
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.
Community buildings like Parish Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Ware station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
