How the job changes by surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard.
Fire rated sealant in North Waltham
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. We work on flats & HMOs, plasterboard & masonry and linear gaps, and the jobs we see most are sealant items on a fire risk assessment action list and linear gaps at the head of walls.
Work in a small place like North Waltham is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Your job is guaranteed for a year, as with all our work.

Honest limits
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Deciding what fire stopping a building needs
- Doors that are not fire doors in the first place
- Construction that does not provide fire resistance on its own

What we are called out for in North Waltham
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
If you can see any of these, it’s time to have the joints looked at:
- Linear gaps at the head of walls
- Gaps flagged on a fire risk assessment
- Cracked or shrunken fire-rated sealant
- Unsealed gaps where pipes and cables go through a wall
If you look after a church, hall or community building such as Church of St. Michael's, older buildings that have had new heating or wiring often have service gaps worth checking.

Common questions in North Waltham
Will you come out to North Waltham?
Yes, North Waltham is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is North Waltham in your area for fire rated sealant?
Yes. We work across London and the South East, and North Waltham is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, 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.
What fire rated sealant looks like in North Waltham
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 work to the specification you are given, installing the product to its tested details.
For landlords with property near Micheldever station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like North Waltham Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Photograph sealed gaps before they’re covered up
- Make resealing part of every contractor’s brief
- Keep the record of products and locations with your fire safety documents
- Check whether a sealant can be painted before decorating over it
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we’ll tell you which one you have.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
Why act early in North Waltham
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In a small place like North Waltham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
