Different surfaces, different methods
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the sealant bonds.
Flats and HMOs
Conversions usually leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
How we handle fire rated sealant in Layston
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. Typical jobs include unsealed gaps around fire door frames and holes left by a change of layout, across plasterboard & masonry, pipe & cable gaps and door frames.
In a village or hamlet like Layston, 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.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Look in service cupboards and ceiling voids from time to time
- Tell trades working in the building that fire seals must be put back
- Store the list of sealed gaps with your building paperwork
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Should I try it myself first?
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 doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Fire doors that need new seals, closers or hardware
- Fire risk assessments, which need a qualified assessor
- Construction that doesn’t provide fire resistance on its own
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Layston questions
Can you do fire rated sealant in Layston?
Yes. We work across London and the South East, and Layston is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Layston?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you tell me which gaps need fire stopping?
No. We work from the specification you give us and install to the manufacturer’s details.
What should I tell you?
Let us know what needs doing and where. If we need more, we will ask.
What does fire rated sealant cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What fire rating will the seal have?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you work in flats, HMOs and commercial buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.
Fire rated sealant in Layston: local notes
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 work to the specification you are given, installing the product to its tested details.
Schools such as Layston Church of England First School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of St Bartholomew (church of England), older buildings that have had new heating or wiring often have service gaps worth checking.

How it works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Layston, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Before we arrive

Advice

What else we do in Layston
Leave it or put it right?
For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Where a wall is exposed, as many are in small places like Layston, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before work begins.
