Workplaces and buildings in Gilbert Street
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
For site and facilities teams at buildings such as Ropley Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Fire rated sealant in Gilbert Street
We can work through a building room by room or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. We work on plasterboard & masonry, pipe & cable gaps and door frames, and common reasons people get in touch are gaps filled with a product that isn’t fire-rated and open holes round services passing through fire walls.
If you have holiday lets, a converted barn used for business or a community building near Gilbert Street, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Gilbert Street questions
Can you do fire rated sealant in Gilbert Street?
Yes, Gilbert Street is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Is Gilbert Street within the area you cover?
Yes. Gilbert Street 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.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you take on fire stopping in schools and offices?
Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Out-of-hours work can be arranged if that suits the building.
How long does the job take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Surface by surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Gilbert Street, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Advice
What affects the quote in Gilbert Street
There’s no set price list, because jobs vary so much. The quote depends on:
- How many areas need sealing
- Whether there’s mould to deal with
- Which sealant suits the joint
- Whether the work is at height
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.
What to tell us for a quote
To make quoting easier, let us know:
- Any previous sealing or DIY work
- How we’d reach the joints
- Pictures of the joints, sent by email
- Roughly how big the job is
For fire rated sealant in Gilbert Street, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we will agree the price before any work begins.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Look in service cupboards and ceiling voids from time to time
- Keep pictures of seals that will be hidden
- Do not paint over fire sealant until it has cured
- Ask every contractor to reseal any fire stopping they disturb
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
Signs you need fire rated sealant in Gilbert Street
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.
It’s worth asking for a quote if you see:
- Open gaps behind door architraves
- Cracked or shrunken fire-rated sealant
- Gaps filled with a product that isn’t fire-rated
- Seals cut through by electricians, plumbers or data installers
For buildings such as Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking.
What to look for in a quote
- What product goes in the joint
- When the joint can take water or movement
- Are they insured?
- What the quote includes, VAT included or not
