Landlord and commercial work in Hawthorn
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Fire rated sealant for homes and businesses in Hawthorn
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Common call-outs are for sealant items on a fire risk assessment action list and fire stopping disturbed by later work, across plasterboard & masonry, linear gaps and pipe & cable gaps.
In a village or hamlet like Hawthorn, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Report cracked or damaged seals as soon as you notice them
- Include fire stopping when you schedule refits
- Keep photos of seals that will be hidden
- Never patch a fire seal with standard sealant
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.
What we are called out for in Hawthorn
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
These are the problems we’re asked about most:
- Standard silicone or caulk in a fire-stopping gap
- New service routes left unsealed after building work
- Linear gaps at the head of walls
- Open holes round services passing through fire walls
If you look after a building such as Reculver Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Before booking anyone
- What product goes in the joint
- When the joint can take water or movement
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing
Leave it or put it right?
For some gaps, sealant is not 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’ll tell you. Around Hawthorn, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before work begins.

Commercial buildings in Hawthorn
If you run a hotel, guest house or holiday let in a coastal place like Hawthorn, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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’re given, installing the product to its tested details.
Rented homes near Herne Bay station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of St Mary the Virgin, older buildings that have had new heating or wiring often have service gaps worth checking.

Different surfaces, different methods
Plasterboard walls

What does intumescent mean?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.
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.

Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you work in occupied buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged if that suits the building.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Do you provide details of the products used?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
