Fire rated sealant in Balmerlawn
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. Typical jobs include cracked or shrunken fire-rated sealant and ordinary sealant used where a fire-rated product was needed, across service penetrations, linear gaps and door frames.
Somewhere as small as Balmerlawn, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
Each job carries a 12-month guarantee, large or small.

Workplaces and buildings in Balmerlawn
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’re given, installing the product to its tested details. There are hotels and other places to stay in and around Balmerlawn. Hotel work can be planned room by room, with out-of-hours working where needed.
Managing a site like Brockenhurst Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Brockenhurst station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What else we do in Balmerlawn
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Allow for resealing whenever new services are run
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Report cracked or damaged seals as soon as you notice them
- Keep pictures of seals that will be hidden
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job generally takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Balmerlawn, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on

Different surfaces, different methods
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall.
Flats and HMOs
Conversions normally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product.
Balmerlawn: your questions answered
Can you help a landlord with a rental near Brockenhurst station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Balmerlawn within the area you cover?
Yes, Balmerlawn is covered. Our work covers 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 take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can you tell me which gaps need fire stopping?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I use normal mastic around a pipe through a fire wall?
No. It looks sealed but won’t perform as fire stopping. A tested fire-rated product is needed.
Should I try it myself first?
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.
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. Everything old must be removed first.
What we are called out for in Balmerlawn
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.
The most common problems we see are:
- Gaps left after a refit or conversion
- Gaps filled with a product that isn’t fire-rated
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
For buildings such as Church of St Nicholas, older buildings that have had new heating or wiring often have service gaps worth checking.

For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Why act early in Balmerlawn
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Balmerlawn, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, 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, and we will explain the quote if you ask.
