About our fire rated sealant in Cooksbridge
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. We work on flats & HMOs, linear gaps and service penetrations, and common reasons people get in touch are open gaps behind door architraves and fire stopping disturbed by later work.
Work in a small place like Cooksbridge is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
Your job is guaranteed for a year, as with all our work.

When to call us in Cooksbridge
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.
These are the problems we are asked about most:
- Open joints along the top of partitions
- Holes left by a change of layout
- Gaps filled with a product that isn’t fire-rated
- Joints picked up in a fire-stopping survey
Community buildings like Church of St Peter are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What happens on the day
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins.

If the job is outside, mention outbuildings, exposed walls and how to reach them.

- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.

Surface by surface
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist and we will mention anything we notice.
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before any work starts so residents know what to expect.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never patch a fire seal with standard sealant
- Store the list of sealed gaps with your building paperwork
- Make resealing part of every contractor’s brief
- Allow for resealing whenever new services are run
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.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.
Questions from Cooksbridge
Can you do fire rated sealant in Cooksbridge?
Yes, Cooksbridge is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Do you cover smaller places like Cooksbridge?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Will we have a record of what was sealed?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
Where do you work from?
Mr Mastic is based in Crawley. We cover Cooksbridge and the rest of East Sussex, along with the rest of our area.
How long does fire rated sealant take?
Most jobs take anything from a few hours to several days, depending on how many gaps there are, including the preparation. Your quote will say how long we expect yours to take.
What does fire rated sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. In a small place like Cooksbridge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What fire rated sealant looks like in Cooksbridge
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 work to the specification you’re given, installing the product to its tested details.
Managing a site like Hamsey Community Primary School? Then fire-stopping around service openings should be restored whenever new services go in. For landlords with property near Cooksbridge station, any gap left by new services in shared walls should be closed with a fire-rated product.
