Fire rated sealant in Clavering, done properly
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. We work on linear gaps, flats & HMOs and plasterboard & masonry, and the jobs we see most are holes left by a change of layout and joints picked up in a fire-stopping survey.
Work in a small place like Clavering is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
A one-year guarantee comes as standard.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. Somewhere as small as Clavering, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- 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.
- Every location is recorded with the product used.

How the job changes by surface
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist, and we will say if we spot a problem with them.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Commercial buildings in Clavering
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.
Community buildings like Church of St Mary and St Clement are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Managing a site like Clavering Primary School? Then service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Newport (Essex) station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

If you manage several properties in or around Clavering, several properties can go on one quote. Just tell us the addresses and what each one needs.
Looking after it afterwards
To keep the joints looking good and working properly:
- Flag any open gap you spot round a pipe or cable
- Store the list of sealed gaps with your building paperwork
- Include fire stopping when you schedule refits
- Check whether a sealant can be painted before decorating over it
Any fire seal that is 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.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
What we cannot put right
In fairness, there are a few things sealant will not fix:
- Deciding what fire stopping a building needs
- Fire doors that need new seals, closers or hardware
- Sign-off of the building, which sits with building control or your assessor
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
