About our fire stopping in Goff's Oak
Facilities managers in Goff's Oak often find open service penetrations when ceilings come down for other work. 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. If you have fire-stopping items raised at inspection or handover and unsealed joints where partitions meet the slab, we can help, whatever the surface. Whoever orders the work in Goff's Oak, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Goff's Oak, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Our workmanship is guaranteed for 12 months, in Goff's Oak as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Aftercare for building managers
Once the work is signed off, these steps help:
- Arrange inspection before areas are covered up
- File the specified details where the next contractor can find them
- Include service cupboards in routine inspections
- Put resealing into every M&E and fit-out package
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
What the job involves on each surface
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.

What else we do in Goff's Oak
When to call us in Goff's Oak
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Clients typically get in touch after noticing one or more of the following:
- Penetration schedules that need working through
- Openings left by services added after handover
- Open linear gaps along the top of fire-resisting walls
- Builders’ foam or ordinary silicone in compartment walls
In a building such as Church of St James, any service penetration through a fire-resisting wall should be sealed to the specified detail.

FAQs: Goff's Oak
Is Goff's Oak too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Sopers Road Industrial Estate, by Goff's Oak?
Yes. Our area takes in Goff's Oak and its surroundings, with estates and business parks such as Sopers Road Industrial Estate included. Photos and a short description are enough for a first look.
Can you fire stop behind the services contractors?
Yes. Send the schedule or marked-up drawings and the specified product details and a fixed quote follows. We can follow the services contractor floor by floor keeping pace with the programme.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Doing it in-house
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, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a site in Goff's Oak, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Send your site hours and access windows
- Have the specification and drawings to hand
- Point out any areas we must not close
Ask for a quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
