Fire rated sealant in Walkern
We can work through a building room by room or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. 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, on linear gaps, pipe & cable gaps and service penetrations.
In a village or hamlet like Walkern, 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.
You get a one-year guarantee, the same in Walkern as everywhere else we work.

Questions from Walkern
Do you cover Walkern for fire rated sealant?
Yes. Our work covers London and the South East, and Walkern is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
Will you come out to Walkern?
Yes, Walkern is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, large or small.
Honest limits
New sealant cannot fix everything, and we will tell you before we start. Sealant won’t put right:
- Problems with the door itself rather than the gap around the frame
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. The work usually takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Walkern needs a little journey planning: 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.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.

Surface by surface
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length.
What happens if it’s left?
Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we’ll tell you. In a small place like Walkern, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.

What fire rated sealant looks like in Walkern
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 work to the specification you’re given, installing the product to its tested details.
If you let a flat or house near Stevenage station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Parish Church of St Mary the Virgin, service openings in its walls need the right fire-rated sealant, as in any building.

The problems people normally mention when they call are:
- Seals cut through by electricians, plumbers or data installers
- Gaps around pipes and cables through fire-resisting walls
- Ordinary sealant used where a fire-rated product was needed
- Gaps where walls meet ceilings or slabs
Managing a site like Walkern Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
