About our fire rated sealant in Great Chesterford
We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We work on plasterboard & masonry, service penetrations and door frames, and the jobs we see most are damaged fire sealant left by other trades and linear gaps at the head of walls.
If you run a pub, café, guest house or shop in or near Great Chesterford, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Your job is guaranteed for a year, as with all our work.

Do you need fire rated sealant in Great Chesterford?
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
These are the problems we are asked about most:
- Fire stopping disturbed by later work
- Gaps around pipes and cables through fire-resisting walls
- Holes left by a change of layout
- Cracked or shrunken fire-rated sealant
Letting a property close to Great Chesterford station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Doors that are not fire doors in the first place

- Construction that doesn’t provide fire resistance on its own

Why it’s worth doing now in Great Chesterford
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. Homes in smaller places like Great Chesterford can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Read how sealant jobs are priced and our reviews.
What affects the cost of fire rated sealant
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Access and height
- How many rooms, windows or areas are involved
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- The address or postcode of the job
- The rough size of the job
- Whether it’s a home or a business
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
What the job involves on each surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail, and we’ll tell you.
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Commercial buildings in Great Chesterford
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 work to the specification you are given, installing the product to its tested details.
For buildings such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Great Chesterford Church of England Primary Academy? Then service openings in fire-resisting walls need checking after any refurbishment.

The process

- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on
- Mention any sign-in or site rules at work premises
