Fire stopping for commercial buildings in Hook Green
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on cable penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and what we’re called in for most is unsealed openings around new pipes and cables and seals that don’t match their tested detail. For commercial sealant work in Hook Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
Smaller places such as Hook Green still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Common problems we fix in Hook Green
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.
Look out for the following:
- Head-of-wall gaps with no fire seal
- Damaged fire seals in risers and voids
- Hidden openings found during inspections
- Builders’ foam or ordinary silicone in compartment walls
In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Hook Green need work, visits can be combined. You’ll have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Flag any permit to work we will need
- Point out parking and an unloading spot
- Share your working hours and any access restrictions

How the job changes by surface
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, along the full length of the run.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter, so we check before sealing.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Agree the fire-stopping specification before services go in
- Flag new cables with no seal around them
- Look above ceilings when tiles are lifted for other jobs
- Foam or ordinary sealant is never a fire-seal repair
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
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, and the work runs in step with the M&E.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, 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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
