Fire rated sealant in Bidden, done properly
Deciding which gaps need fire stopping isn’t our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on linear gaps, flats & HMOs and plasterboard & masonry, and common reasons people get in touch are open gaps behind door architraves and standard silicone or caulk in a fire-stopping gap.
For holiday lets, converted business premises or a community building near Bidden, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Our work is backed for twelve months, in Bidden and everywhere else we cover.

Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Older cottages and farmhouses around Bidden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What affects the cost of fire rated sealant
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
To make quoting easier, please include:
- If someone has resealed it before
- Where the property is
- How we’d reach the joints
- Roughly how big the job is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.
When to call us in Bidden
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Keep an eye out for these signs:
- Fire seals that have cracked with movement
- Linear gaps at the head of walls
- Door frames with gaps between frame and wall
- Sealant items on a fire risk assessment action list
If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.
What your quote should include
- Which colour the sealant will be
- What insurance they hold
- What happens if they find a problem under the old sealant
- What the quote includes, VAT included or not
What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In a small place like Bidden, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Before we arrive
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Bidden: your questions answered
Do you work for landlords with property near Hook station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you cover smaller places like Bidden?
Yes, Bidden is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What does intumescent mean?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Can you give us a record of the work?
Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Bidden.
Surface by surface
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Fire rated sealant in Bidden: 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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Robert May's School, service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Hook station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
