About our fire rated sealant in Plaish
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment on buildings across Plaish. If you share the list, we can quote for the gaps that need fire-rated sealant. We work on door frames, plasterboard & masonry and pipe & cable gaps, and the jobs we see most are holes left by a change of layout and cracked or shrunken fire-rated sealant.
If you have holiday lets, a converted barn used for business or a community building near Plaish, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
All our work comes with our 12-month guarantee, wherever you are in the Isle of Wight.

Different surfaces, different methods
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment room by room.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Quotes for fire rated sealant in Plaish
Jobs vary more than people expect. What affects the quote:
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- The product the joint needs
- When we can work, for business premises
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Helping us quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
For a quote, ring 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
If you manage several properties in or around Plaish, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Questions from Plaish
Will you come out to Plaish?
Yes. Plaish 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.
Do you cover Plaish for fire rated sealant?
Yes. We work across London and the South East, and Plaish is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you seal gaps around fire door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame and we will tell you if we spot problems with the door.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you take on fire stopping in schools and offices?
Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Out-of-hours work can be arranged where it’s needed.
Why deal with it now?
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In a small place like Plaish, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Workplaces and buildings in Plaish
There are hotels and other places to stay in and around Plaish. Hotel work can be planned room by room, with out-of-hours working where needed. 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 buildings such as Church of St. Nicholas in Castro, older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as St Thomas of Canterbury Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Advice
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Check whether a sealant can be painted before decorating over it
- Ask every contractor to reseal any fire stopping they disturb
- Include hidden areas like risers in routine checks
- Store the list of sealed gaps with your building paperwork
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
