Fire rated sealant for homes and businesses in Lashenden
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. Common call-outs are for damaged fire sealant left by other trades and open holes round services passing through fire walls, across door frames, pipe & cable gaps and flats & HMOs.
For a small place like Lashenden, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
All our work is covered by a 12-month guarantee, wherever you are in Kent.

When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
- Doors that are not fire doors in the first place
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Pipe & cable gaps
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Door frames
- Linear gaps
Aftercare tips
So the new joints stay in good condition:
- Report cracked or damaged seals as soon as you notice them
- File the fire-stopping record where your assessor can find it
- Do not paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
Commercial buildings in Lashenden
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Can you do fire rated sealant in Lashenden?
Yes, Lashenden is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Lashenden?
Yes. Lashenden is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I use normal mastic around a pipe through a fire wall?

Do you carry out fire risk assessments?
No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
How much does fire rated sealant cost in Lashenden?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The process
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for a handful of gaps, and longer for a whole building, depending on the amount of work. Somewhere like Lashenden 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.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules

How the job changes by surface
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.
What we are called out for in Lashenden
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
It’s worth asking for a quote if you see:
- Damaged fire sealant left by other trades
- Sealant items on a fire risk assessment action list
- Open gaps behind door architraves
- Ordinary sealant used where a fire-rated product was needed
If you let a flat or house near Headcorn station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Questions to ask before booking
- How hidden problems are handled
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- Whether you can choose the colour
