Your questions about fire rated sealant in Baffins
Is Baffins in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Baffins is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Baffins?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you certify the fire stopping?
Ratings and certificates aren’t something we issue. 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.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
How do I get a quote for fire rated sealant in Baffins?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Fire rated sealant in Baffins, done properly
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. We work on pipe & cable gaps, service penetrations and door frames, and the jobs we see most are open joints along the top of partitions and standard silicone or caulk in a fire-stopping gap.
For a pub, café, guest house or shop in or near Baffins, its washrooms and kitchen need the same sealant care as any big building.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Different surfaces, different methods
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Doors that are not fire doors in the first place
- Certifying a building or signing off its fire safety
- Openings too large for sealant, which need batts, boards or another system
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
What we seal
- Door frames
- Plasterboard & masonry
- Service penetrations

- Pipe & cable gaps
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. In a smaller place like Baffins, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
How to prepare
- Clear the area around the work
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

Quotes for fire rated sealant in Baffins
Jobs vary more than people expect. What affects the quote:
- Which sealant suits the joint
- The number of rooms or windows
- Mould in or behind the old joints
- The old material and how stubborn it is
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Where the property is
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. We will give you a clear price before any work starts.
For landlords and businesses
If you manage several properties in or around Baffins, several properties can go on one quote. Just tell us the addresses and what each one needs.
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Commercial buildings in Baffins
If you run a hotel, guest house or holiday let in a coastal place like Baffins, 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. 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 buildings such as Church of St Cuthbert, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Fratton station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Langstone Junior Academy, fire-stopping around service openings should be restored whenever new services go in.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Why act early in Baffins
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Around Baffins, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
