Fire stopping for commercial buildings in Great Chesterford
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on pipe penetrations, cable penetrations and service gaps in risers, and the failures we’re asked to look at most are fire seals cut back for extra cables and never reinstated and fire stopping installed outside its tested range. For commercial sealant work in Great Chesterford, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In places the size of Great Chesterford, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why it’s worth doing now in Great Chesterford
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Quoting for work in Great Chesterford
A fixed quote reflects the actual work. It allows for:
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- Any access equipment needed
- The total length or number of joints
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Details that help us quote
A few photographs plus some basic facts will normally do. It helps to include:
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- Anything awkward about access or site hours
- The site address and postcode
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
After the work
To get the most from the new sealant:
- Check risers and ceiling voids after each round of works
- Keep general-purpose fillers away from compartment walls
- Ask the designer to confirm details early on refits
- Keep product data and details in the fire safety file
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
How the job changes by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Questions about Great Chesterford
Is Great Chesterford off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you cover business parks and estates near Great Chesterford, such as Abbey Barns Business Park?
Yes. We cover Great Chesterford and the area around it, including industrial estates, business parks and retail parks such as Abbey Barns Business Park. Send details of the unit and the work through our quote form for a quick quote.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
Is sealant suitable for all service openings?
No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we’ll tell you when that applies.
Is fire stopping in Scotland covered by different guidance?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
