How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Andwell needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Advice
About our fire rated sealant in Andwell
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. If you are dealing with sealant items on a fire risk assessment action list and gaps filled with a product that isn’t fire-rated, we can put it right, on pipe & cable gaps, plasterboard & masonry and door frames alike.
In a village or hamlet like Andwell, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Whatever the size of the job, you get the same 12-month guarantee.

What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- Fire risk assessments, which need a qualified assessor
- Construction that does not provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

What else we do in Andwell
Fire rated sealant around Andwell
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
For buildings such as St Swithun's church, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Hook station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Andwell: your questions answered
I let a flat near Hook station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Andwell?
Yes, Andwell is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.
Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before we start.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Around Andwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Take a look at how sealant jobs are priced and what customers say.
Surface by surface
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing.
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
