About our fire rated sealant in Saint Hill Green
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’s the part we focus on, gap by gap. We work on pipe & cable gaps, service penetrations and door frames, and people most often call us about door frames with gaps between frame and wall and fire seals that have cracked with movement.
For holiday lets, converted business premises or a community building near Saint Hill Green, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How the job changes by surface
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail.

What else we do in Saint Hill Green
What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Saint Hill Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

Work for landlords, hotels and businesses

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Older cottages and farmhouses around Saint Hill Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

How we quote for fire rated sealant
The price is agreed before any work begins. It takes into account:
- Any working-time requirements on site
- Which sealant suits the joint
- How easy the joints are to reach
- The number of rooms or windows
Doing several joints on one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Asking for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Whether it has been sealed before
- The rough size of the job
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Do you need fire rated sealant in Saint Hill Green?
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
People normally contact us after spotting something like this:
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
- Cracked or shrunken fire-rated sealant
- Joints picked up in a fire-stopping survey
If you look after a church, hall or community building such as St. Barnabas Church, service openings in its walls need the right fire-rated sealant, as in any building.

Questions from Saint Hill Green
Do you cover smaller places like Saint Hill Green?
Yes. Saint Hill Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near East Grinstead station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Saint Hill Green.
Can you tell me how many minutes the seal will last?
That isn’t something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Fire rated sealant in Saint Hill Green: local notes
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, 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.
For site and facilities teams at buildings such as The Meads Primary School, fire-stopping around service openings should be restored whenever new services go in. For landlords with property near East Grinstead station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
