Fire rated sealant in High Garrett
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on service penetrations, door frames and linear gaps, and common reasons people get in touch are gaps where walls meet ceilings or slabs and joints picked up in a fire-stopping survey.
For a small place like High Garrett, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Why act early in High Garrett
Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Older cottages and farmhouses around High Garrett can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

If the job is outside, mention outbuildings, exposed walls and how to reach them.

- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Move anything stored near the joints

How to look after the new joints
After the cure time, these simple habits help:
- Include fire stopping when you schedule refits
- Don’t paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
- Photograph sealed gaps before they’re covered up
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
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.
Different surfaces, different methods
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the sealant bonds.
Honest limits
Before you book, it’s worth knowing the limits:
- Issuing a fire rating or certificate for a building
- Problems with the door itself rather than the gap around the frame
- Openings too large for sealant, which need batts, boards or another system
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Door frames
- Plasterboard & masonry
- Flats & HMOs
- Service penetrations
- Pipe & cable gaps
- Linear gaps
Do you need fire rated sealant in High Garrett?
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.
Keep an eye out for any of the following:
- Cracked or shrunken fire-rated sealant
- New service routes left unsealed after building work
- Seals cut through by electricians, plumbers or data installers
- Open holes round services passing through fire walls
Letting a property close to Braintree station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Fire rated sealant in High Garrett: local notes
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.
Managing a site like Bocking Church Street Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
