About our fire rated sealant in Thurnham
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Thurnham. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. We are often asked to deal with sealant items on a fire risk assessment action list and cracked or shrunken fire-rated sealant, on service penetrations, door frames and flats & HMOs.
In a village or hamlet like Thurnham, 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.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere like Thurnham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Getting ready for the visit

Aftercare tips
Good habits help new joints last longer. Our tips:
- Include fire stopping when you schedule refits
- Report cracked or damaged seals as soon as you notice them
- Ask which product was used before you paint
- Keep the record of products and locations with your fire safety documents
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Surface by surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
When something else is needed
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Fire risk assessments, which need a qualified assessor
- Construction that doesn’t provide fire resistance on its own
- Certifying a building or signing off its fire safety
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal
- Service penetrations
- Door frames
- Pipe & cable gaps
- Linear gaps
- Flats & HMOs
- Plasterboard & masonry
Leave it or put it right?
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 doesn’t depend on other work. Older cottages and farmhouses around Thurnham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Commercial buildings in Thurnham
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, 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.
If you let a flat or house near Bearsted station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as Valley Park School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. For buildings such as St Mary the Virgin Church, gaps around pipes and cables are worth checking after any building work there.

Thurnham questions
Is Thurnham within the area you cover?
Yes. Thurnham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do fire rated sealant in Thurnham?
Yes. Our work covers London and the South East, and Thurnham is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can you match the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
What fire rating will the seal have?
We do not give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it, recording the locations and products.
Can you give us a record of the work?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on how many gaps there are. We’ll confirm how long when we quote.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
For landlords and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
