Fire rated sealant in Barnsbury
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Barnsbury. If you share the list, we can quote for the gaps that need fire-rated sealant. We work on linear gaps, service penetrations and door frames, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and unsealed gaps around fire door frames.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Barnsbury, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Each job carries a 12-month guarantee.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. For a job in Barnsbury, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in

Advice
Landlords, agents and businesses in Barnsbury
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
For anyone letting property in or around Barnsbury, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Ask which product was used before you paint
- Report cracked or damaged seals as soon as you notice them
- Tell trades working in the building that fire seals must be put back
- File the fire-stopping record where your assessor can find it
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we will tell you which one you have.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Honest limits
It helps to know what we cannot do too:
- Construction that doesn’t provide fire resistance on its own
- Doors that are not fire doors in the first place
- Issuing a fire rating or certificate for a building
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

Commercial buildings in Barnsbury
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. Barnsbury has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Rented homes near Caledonian Road & Barnsbury station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Former Church of St Clement, older buildings that have had new heating or wiring often have service gaps worth checking.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.

What else we do in Barnsbury
What we’re called out for in Barnsbury
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
If you can see any of these, it’s time to have the joints looked at:
- Open holes round services passing through fire walls
- Gaps flagged on a fire risk assessment
- Fire stopping disturbed by later work
- Gaps where walls meet ceilings or slabs
As a London address, Barnsbury can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Comparing quotes

- What product goes in the joint
Surface by surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for each gap size.
Barnsbury: your questions answered
Do you work for landlords with property near Caledonian Road & Barnsbury station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can parking be tricky for a visit in Barnsbury?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you work in flats, HMOs and commercial buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do I need to be at home?
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.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can you tell me how many minutes the seal will last?
That is not something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it.
