About our fire rated sealant in Chartridge
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have standard silicone or caulk in a fire-stopping gap and old fire sealant that has split or come away, we can help, whatever the surface.
In a village or hamlet like Chartridge, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

When something else is needed
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

How the job changes by surface
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth with backing where the detail needs it.
What affects the cost of fire rated sealant
You’ll get a clear quote before we start. It’s based on:
- Access and height
- Working hours on commercial sites
- How many areas need sealing
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Helping us quote
What to tell us when you ask for a quote:
- Photos by email, if that is easy
- What’s wrong with the joints now
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To get started, call 0345 464 0079 or drop us an email.
What happens if it’s left?
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Around Chartridge, older homes often have timber in their 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: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Chartridge: your questions answered
Do you cover smaller places like Chartridge?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Chartridge in your area for fire rated sealant?
Yes, Chartridge is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. Your quote will say how long we expect yours to take.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will we have a record of what was sealed?
Yes. Every gap we seal is listed with the product used.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

More services for Chartridge
Commercial buildings in Chartridge
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.
If you look after a building such as Chartridge Combined School, fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as St John's Church, service openings in its walls need the right fire-rated sealant, as in any building.

Common problems we fix in Chartridge
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
Most people get in touch after spotting one of these:
- Ordinary sealant used where a fire-rated product was needed
- Fire stopping disturbed by later work
- Cracked or shrunken fire-rated sealant
- Gaps flagged on a fire risk assessment
Letting a property close to Great Missenden station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
