General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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 usually costs more in the end than doing them right.
How we handle fire stopping in South Harewood
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads, and the failures we’re asked to look at most are damaged fire seals in risers and voids and unsealed penetrations discovered above suspended ceilings. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in South Harewood is the same: the right product in a properly prepared joint.
Around smaller places like South Harewood, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Fire stopping in South Harewood: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 61 miles from South Harewood. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
On estates like Harewood Forest Industrial Estate, 0.7 miles north of South Harewood, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Hospital estates such as Andover War Memorial Hospital (4.3 miles north-west of South Harewood) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
South Harewood is about 4 miles south-east of Andover, in Hampshire. Anywhere in SP11, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

What we are called out for in South Harewood
Openings in fire-resisting walls typically appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
These are often picked up first by site or facilities staff:
- Fire sealant pulled out of the opening
- Head-of-wall gaps with no fire seal
- Openings found when ceilings come down for a refit
- Non-fire-rated filler around services
Holiday works at schools like Wherwell Primary School often leave service openings to seal before pupils return.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their public liability cover
- Is the sealant right for the movement and the substrate?
- Health and safety accreditation such as CHAS
Keeping the joints sound
For the best life from the joints:
- Record which product was used where
- Keep general-purpose fillers away from compartment walls
- Ask which product is in place before decorating
- Brief every trade that openings they make must be sealed
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.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Writing the fire-stopping specification
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly.
