Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
About our fire rated sealant in Nursling
Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and common reasons people get in touch are fire seals that have cracked with movement and linear gaps at the head of walls.
If you run a pub, café, guest house or shop in or near Nursling, its washrooms and kitchen need the same sealant care as any big building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of fire rated sealant
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- The type of sealant required
- Access and height
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The type of property
- A few pictures by email, if you can
- Roughly how big the job is
- The problem you’ve noticed
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work.
What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Certifying a building or signing off its fire safety
- Problems with the door itself rather than the gap around the frame
- Big openings where sealant alone is not the tested solution
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
Surfaces we seal
- Flats & HMOs
- Pipe & cable gaps

Nursling: your questions answered
Is Nursling in your area for fire rated sealant?
Yes, Nursling is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you help a landlord with a rental near Redbridge station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Can you fill the gap behind a fire door frame?
Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door leaf and its hardware need a door specialist.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Where do you work from?
Mr Mastic is based in Crawley. We cover Nursling and the rest of Southampton.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

What fire rated sealant looks like in Nursling
If you run a hotel, guest house or holiday let in a coastal place like Nursling, 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Rented homes near Redbridge station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Nursling Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of gaps, and longer for a whole building. A visit to Nursling is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can

Related advice
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Photograph sealed gaps before they’re covered up
- Never patch a fire seal with standard sealant
- File the fire-stopping record where your assessor can find it
- Don’t paint over fire sealant until it has cured
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
Common problems we fix in Nursling
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Signs it’s time to call us include:
- Fire seals that have cracked with movement
- Unsealed gaps where pipes and cables go through a wall
- Open joints along the top of partitions
- New service routes left unsealed after building work
For buildings such as Lord's Hill Church, service openings in its walls need the right fire-rated sealant, as in any building.
