What affects the quote in Clement Street
The quote reflects the job in front of us. We take into account:
- Whether there’s mould to deal with
- Which sealant suits the joint
- Whether the work is at height
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Roughly how big the job is
- The address or postcode of the job
- A few photos by email, if you can
- Whether it has been sealed before
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Fire rated sealant in Clement Street, done properly
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That is the part we focus on. We work on door frames, linear gaps and service penetrations, and the jobs we see most are gaps filled with a product that isn’t fire-rated and cracked or shrunken fire-rated sealant.
For a small place like Clement Street, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What fire rated sealant looks like in Clement Street
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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
Schools such as Sutton-At-Hone Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Farningham Road station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. For a village or hamlet like Clement Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What sealant work cannot fix
It helps to know what we cannot do too:
- Problems with the door itself rather than the gap around the frame
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Clement Street questions
I let a flat near Farningham Road station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Is Clement Street in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Clement Street is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll tell you how long to expect.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you give us a record of the work?
Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.
Can you work in occupied buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine. Out-of-hours work can be arranged if that suits the building.
What does fire rated sealant cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Clement Street and the rest of Kent, along with the rest of our area.
Why act early in Clement Street
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Older cottages and farmhouses around Clement Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

When to call us in Clement Street
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
It’s worth asking for a quote if you see:
- Open gaps behind door architraves
- Linear gaps at the head of walls
- Damaged fire sealant left by other trades
- Standard silicone or caulk in a fire-stopping gap
If you look after a church, hall or community building such as Church of Saint Paul, service openings in its walls need the right fire-rated sealant, as in any building.
