- Open holes round services passing through fire walls
- Joints picked up in a fire-stopping survey
- Standard silicone or caulk in a fire-stopping gap
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
How we handle fire rated sealant in Norton
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We are often asked to deal with joints picked up in a fire-stopping survey and unsealed gaps where pipes and cables go through a wall, across service penetrations, flats & HMOs and door frames.
If you have holiday lets, a converted barn used for business or a community building near Norton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
There’s a 12-month guarantee on every job, whatever its size.

Why deal with it now?
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. Where a wall is exposed, as many are in small places like Norton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

How the job changes by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
When it is not the sealant
Before you book, it’s worth knowing the limits too:
- Issuing a fire rating or certificate for a building
- Large holes that need a different fire-stopping system
- Walls or floors that weren’t built to resist fire
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Plasterboard & masonry
- Service penetrations
- Flats & HMOs
- Door frames
- Pipe & cable gaps
- Linear gaps

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
How to look after the new joints
Aftercare is simple:
- File the fire-stopping record where your assessor can find it
- Make resealing part of every contractor’s brief
- Take pictures of fire stopping before ceilings or boxing go back
- Check whether a sealant can be painted before decorating over it
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
How the visit works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. In a small place like Norton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

Workplaces and buildings in Norton
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, 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 The Parish Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Ormiston Six Villages Academy are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Barnham station, any gap left by new services in shared walls should be closed with a fire-rated product.
