About our fire rated sealant in Sandling
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Sandling. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on plasterboard & masonry, linear gaps and pipe & cable gaps, and the jobs we see most are holes left by a change of layout and cracked or shrunken fire-rated sealant.
Somewhere as small as Sandling, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Every job comes with a one-year guarantee, wherever you are in Kent.

What affects the cost of fire rated sealant
You’ll get a clear quote before work begins. It’s based on:
- The product the joint needs
- Working hours on commercial sites
- The amount of work
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
When you call or email, these details help:
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
Getting a quote is simple: let us know what needs doing and where. A few photos by email make the job easier to understand, and we’ll take it from there.
What we are called out for in Sandling
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common particularly when it was the last job before handover.
Signs it’s time to call us include:
- Gaps filled with a product that is not fire-rated
- New service routes left unsealed after building work
- Open gaps behind door architraves
- Fire stopping disturbed by later work
For site and facilities teams at buildings such as Brockhill Park Performing Arts College, fire-stopping around service openings should be restored whenever new services go in.
What to look for in a quote
- How hidden problems are handled
- What the cure time is
- Who does the work, and how experienced they are
- Which colour the sealant will be

What else we do in Sandling
Sandling: your questions answered
Do you cover Sandling for fire rated sealant?
Yes. Our work covers London and the South East, and Sandling is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
I let a flat near Sandling station. Can you help?
Yes, landlords and agents are among the people we work for, 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.
How long will you be here?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you do fire sealant around door frames?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the 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.
What fire rated sealant looks like in Sandling
If you run a hotel, guest house or holiday let in a coastal place like Sandling, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
Community buildings like Church of St Peter and St Paul are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Letting a property close to Sandling station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Local landmarks in Sandling
Typical jobs here are in homes near St Augustine's Catholic Primary School and Brockhill Country Park, among other places. There’s a railway station in Sandling itself: Sandling station. A little further out are Saltwood Castle (0.9 miles south-east) and Hythe Museum (1.4 miles south-east). For a walk, there’s Tolsford Hill.
Why it’s worth doing now in Sandling
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. In a small place like Sandling, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Fire risk assessments, which need a qualified assessor
- Certifying a building or signing off its fire safety
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. For a village or hamlet like Sandling, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Tell us about any water getting in

Advice
Different surfaces, different methods
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product.
