How we handle fire rated sealant in Maze Hill
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We are often asked to deal with unsealed gaps where pipes and cables go through a wall and unsealed gaps around fire door frames, on linear gaps, pipe & cable gaps and plasterboard & masonry.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Maze Hill.
A one-year guarantee comes as standard.

How to look after the new joints
To keep the joints looking good and working properly:
- Keep pictures of seals that will be hidden
- Make resealing part of every contractor’s brief
- Include fire stopping when you schedule refits
- Check whether a sealant can be painted before decorating over it
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
What affects the cost of fire rated sealant
Your quote is based on your job. We take into account:
- The product the joint needs
- How many rooms, windows or areas are involved
- The number and length of the joints
- Any mould that needs treating
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

- The rough size of the job

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Why deal with it now?
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In a flat in Maze Hill, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
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. Call for a quick quote and we’ll explain what it covers.

Workplaces and buildings in Maze Hill
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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.
Community buildings like Christ Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Managing a site like John Roan School? Then fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Maze Hill station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Fire doors that need new seals, closers or hardware

- Openings too large for sealant, which need batts, boards or another system
