Fire rated sealant in Cox Green, done properly
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you have gaps flagged on a fire risk assessment and gaps around pipes and cables through fire-resisting walls, we can put it right.
Around a place like Cox Green, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Cox Green, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Cox Green questions
Do you take on hotel work around Cox Green?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you help a landlord with a rental near Maidenhead station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you seal gaps around fire door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.
Should I try it myself 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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Workplaces and buildings in Cox Green
Cox Green has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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 Maidenhead station, any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like All Saints' Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What else we do in Cox Green
What affects the cost of fire rated sealant
You’ll get a clear quote before work begins. It’s based on:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
To make quoting easier, please include:
- Where the property is
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
Want a quote for fire rated sealant? Please call 0345 464 0079 or email us with a few details. We will explain what we’d do and give you a clear price before we start.
Why deal with it now?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that does not depend on other work. In an older home around Cox Green, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.
Why choose Mr Mastic in Cox Green
- We leave the area clean and tidy
- Domestic, commercial and hotel work
- An ARBOMaster approved applicator
- A 12-month guarantee on all work
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Store the list of sealed gaps with your building paperwork
- Plan fire stopping into any work that goes through walls or floors
- Photograph sealed gaps before they’re covered up
- Don’t fill fire-stopping gaps with ordinary foam or silicone
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
Signs you need fire rated sealant in Cox Green
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
The problems people generally mention when they call are:
- Gaps around pipes and cables through fire-resisting walls
- Cracked or shrunken fire-rated sealant
- Ordinary sealant used where a fire-rated product was needed
- Fire stopping disturbed by later work
Schools such as Wessex Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
