- Ordinary sealant used where a fire-rated product was needed
- Joints picked up in a fire-stopping survey
- Unsealed gaps where pipes and cables go through a wall
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
How we handle fire rated sealant in Hill Brow
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. We’re often asked to deal with gaps filled with a product that isn’t fire-rated and unsealed gaps where pipes and cables go through a wall, across flats & HMOs, pipe & cable gaps and service penetrations.
Work in a small place like Hill Brow is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
Our work is backed for twelve months, in Hill Brow and everywhere else we cover.

Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. Where a wall is exposed, as many are in small places like Hill Brow, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

Do you need fire rated sealant in Hill Brow?
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
These are the problems we’re asked about most:
- Cracked or shrunken fire-rated sealant
- Seals cut through by electricians, plumbers or data installers
- Sealant items on a fire risk assessment action list
- Holes left by a change of layout
If you look after a building such as Liss Junior School, fire-stopping around service openings should be restored whenever new services go in.

Hill Brow: your questions answered
Can you help a landlord with a rental near Liss station?

Do you take on hotel work around Hill Brow?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Hill Brow.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you certify the fire stopping?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you tell me which gaps need fire stopping?
No. We work from the specification you give us, and apply each product to its tested details.
Fire rated sealant around Hill Brow
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. There are hotels and other places to stay in and around Hill Brow. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
For landlords with property near Liss station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Rake Mission Church, service openings in its walls need the right fire-rated sealant, as in any building.
