About our fire rated sealant in Mill End
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That is the part we focus on. We work on service penetrations, door frames and flats & HMOs, and the jobs we see most are sealant items on a fire risk assessment action list and damaged fire sealant left by other trades.
For a pub, café, guest house or shop in or near Mill End, the washrooms and kitchen need the same attention as a big site.
Each job carries a 12-month guarantee, whatever its size.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. For a job in Mill End, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Let us know about parking restrictions

Advice
Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product.
When to call us in Mill End
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
The problems people normally mention when they call include:
- Fire stopping disturbed by later work
- Cracked or shrunken fire-rated sealant
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
Schools such as St Peter's Church of England Voluntary Aided Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
Before booking anyone
- Is the old sealant removed completely?
- How long to leave it before use
- What preparation is included
- Which colour the sealant will be
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Allow for resealing whenever new services are run
- Flag any open gap you spot round a pipe or cable
- File the fire-stopping record where your assessor can find it
- Check risers, ceiling voids and cupboards during building checks
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
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.

Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

No. Where a fire-rated seal is needed, it has to be a product tested for that use.

Fire rated sealant in Mill End: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 let a flat or house near Rickmansworth station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there.

How we quote for fire rated sealant
Your quote is based on your job. We look at:
- Which sealant suits the joint
- Whether the work is at height
- How many rooms, windows or areas are involved
- Working hours on commercial sites
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

- The address or postcode of the job
- If it’s domestic, commercial or a hotel

Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Construction that does not provide fire resistance on its own
- Assessing a building’s fire safety
- Openings too large for sealant, which need batts, boards or another system
