How we handle fire stopping in Great Lea Common
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Great Lea Common. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and service gaps in risers, and what we are called in for most is fire-stopping items raised at inspection or handover and head-of-wall gaps with no fire seal. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Great Lea Common is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Barn and farm-building conversions near places like Great Lea Common often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Our workmanship is guaranteed for 12 months, in Great Lea Common as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Cost factors for service penetrations
Before we quote, we look at:
- Whether the work must be split into stages
- How accessible the joints are
- Joint width, depth and condition
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Anything awkward about access or site hours
- What the building is and how it’s used
- The site address and postcode
- Approximate linear metres or a joint schedule
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Don’t let anyone top up a fire seal with the wrong product
- Get seals inspected before ceilings and boxing close
- Check risers and ceiling voids after each round of works
- Brief every trade that openings they make must be sealed
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
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.
When something else is needed
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Deciding what a wall or floor needs, which belongs to the designer
- Fire risk assessments, a job for a competent assessor
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, call 01277 525 020 or email us and we’ll say what we think before you book.
What we seal
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors
Different surfaces, different methods
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
Metal pipes
Heat travels along metal pipework, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Great Lea Common, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Tell us which areas need to stay in use
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements

Other services in Great Lea Common
Do you need fire stopping in Great Lea Common?
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.
It’s worth sending us details if you spot any of the following:
- Unsealed joints where partitions meet the slab
- Expanding foam used as fire stopping
- Fire stopping installed outside its tested range
- Seals disturbed by maintenance and left open
Older community buildings such as St Paul's Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- What level of public liability insurance do they hold?
- Will CSCS-carded applicators be on site?
- Health and safety accreditation such as CHAS
