How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes anything from a few hours to several days, depending on how many gaps there are, depending on the size of the job. Somewhere like Kidmore End 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 start with the survey or action list, checking the size and surfaces of every gap.
- 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.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

What else we do in Kidmore End
What we’re called out for in Kidmore End
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Signs it’s time to call us include:
- Gaps flagged on a fire risk assessment
- Seals cut through by electricians, plumbers or data installers
- Unsealed gaps around fire door frames
- Open joints along the top of partitions
Community buildings like Church of St John the Baptist are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
What your quote should include
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- How long the guarantee is
- Whether you can choose the colour
Work for landlords, hotels and businesses

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Questions from Kidmore End
I let a flat near Tilehurst 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 give you a clear quote.
Can you do fire rated sealant in Kidmore End?
Yes. Our work covers London and the South East, and Kidmore End is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.

What affects the quote in Kidmore End
We do not publish a price list, because jobs vary so much. What we look at:
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- The product the joint needs
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
When you call or email, these details help:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- If someone has resealed it before
- Photos by email, if that is easy
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Flag any open gap you spot round a pipe or cable
- Plan fire stopping into any work that goes through walls or floors
- Do not paint over fire sealant until it has cured
- Keep pictures of seals that will be hidden
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Surface by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before applying the sealant.
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins so residents know what to expect.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
