Fire rated sealant in Blackfield
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. If you are dealing with open gaps behind door architraves and new service routes left unsealed after building work, we can put it right.
Commercial work around a smaller place like Blackfield usually means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What fire rated sealant looks like in Blackfield
If you run a hotel, guest house or holiday let in a coastal place like Blackfield, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Blackfield has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Community buildings like St Francis are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Hamble station, any gap left by new services in shared walls should be closed with a fire-rated product.

Blackfield: your questions answered
Will you come out to Blackfield?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Hamble station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, large or small.
Can you tell me which gaps need fire stopping?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Do you certify the fire stopping?
That is not something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it, recording the locations and products.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
How do I get a quote for fire rated sealant in Blackfield?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Tell trades working in the building that fire seals must be put back
- Report cracked or damaged seals as soon as you notice them
- Keep the record of products and locations with your fire safety documents
- Never patch a fire seal with standard sealant
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we’ll tell you which one you have.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
How we quote for fire rated sealant
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- How many areas need sealing
- How easy the joints are to reach
- The number and length of the joints
Doing several joints on one visit normally 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.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
What the job involves on each surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. A visit to Blackfield is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

Related advice
Leave it or put it right?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In an older home around Blackfield, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

When to call us in Blackfield
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
If you can see any of these, it’s time to have the joints looked at:
- Damaged fire sealant left by other trades
- Ordinary sealant used where a fire-rated product was needed
- New service routes left unsealed after building work
- Gaps around pipes and cables through fire-resisting walls
Schools such as Blackfield Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
Before booking anyone
- Whether they’re fully insured
- What guarantee comes with the work
- When the joint can take water or movement
- Is the old sealant removed completely?
