Fire stopping for Hadham Cross sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Owners, agents and contractors
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Fire stopping in Hadham Cross
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about unsealed joints where partitions meet the slab and fire seals cut back for extra cables and never reinstated, on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and cable penetrations. For commercial sealant work in Hadham Cross, you deal with one contact from quote to sign-off, whether it’s one building or several.
Smaller places such as Hadham Cross still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Common questions from Hadham Cross clients
Is Hadham Cross too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Is a hospital such as Herts and Essex Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you design or specify fire stopping?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.
Do you hold third-party fire-stopping installer certification?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Doing it in-house
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What else we do in Hadham Cross
Why deal with it now?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. One visit to deal with every failing joint makes more sense than several trips to a place like Hadham Cross. Photos of every joint help us quote for the whole job.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What you get with us
- CSCS-carded applicators
- A fixed quote before work starts
- 12 months’ guarantee on every job
- Fully insured, including public liability cover
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Hadham Cross, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Have the specification and drawings to hand

Signs you need fire stopping in Hadham Cross
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Things that usually lead to an enquiry:
- Unsealed openings around new pipes and cables
- Open linear gaps along the top of fire-resisting walls
- Expanding foam used as fire stopping
- Unsealed penetrations discovered above suspended ceilings
Older community buildings such as Church of St Thomas that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
