Honest limits
New sealant cannot fix everything, and we will tell you before we start. Sealant won’t put right:
- Deciding what fire stopping a building needs
- Construction that doesn’t provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system

How we handle fire rated sealant in Colney Street
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you’re dealing with sealant items on a fire risk assessment action list and standard silicone or caulk in a fire-stopping gap, we can put it right, whatever the surface.
In a village or hamlet like Colney Street, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What fire rated sealant looks like in Colney Street
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 site and facilities teams at buildings such as Park Street Church of England Voluntary Aided Primary School, fire-stopping around service openings should be restored whenever new services go in. For landlords with property near How Wood station, any gap left by new services in shared walls should be closed with a fire-rated product.

Why act early in Colney Street
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. In a small place like Colney Street, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Do you need fire rated sealant in Colney Street?
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Look out for these signs:
- New service routes left unsealed after building work
- Unsealed gaps where pipes and cables go through a wall
- Unsealed gaps around fire door frames
- Gaps filled with a product that isn’t fire-rated
If you look after a church, hall or community building such as Church of the Holy Trinity, service openings in its walls need the right fire-rated sealant, as in any building.

Keeping the joints in good condition
So the new joints stay in good condition:
- Report cracked or damaged seals as soon as you notice them
- Never patch a fire seal with standard sealant
- Include fire stopping when you schedule refits
- Photograph sealed gaps before they’re covered up
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
