General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
About our fire stopping in Bricket Wood
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve fire stopping installed outside its tested range and seals disturbed by maintenance and left open, across service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations. A single leaking joint is often how a building in Bricket Wood first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In places the size of Bricket Wood, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Surface by surface
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.
Why it’s worth doing now in Bricket Wood
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Bricket Wood: questions and answers
Is a smaller place like Bricket Wood outside your area?
Not at all. Bricket Wood is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you cover business parks and estates near Bricket Wood, such as Colne Way Industrial Estate?
Yes. Estates, retail parks and business parks around Bricket Wood, Colne Way Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How do we ask for a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email us. Include photographs or drawings if you have them.
Do you seal openings left by new services?
Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If neighbouring businesses or buildings around Bricket Wood need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.

Approved Document B is the English guidance that covers fire stopping around openings and penetrations.

Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Check with the data sheet before painting over fire sealant
- Look above ceilings when tiles are lifted for other jobs
- Record which product was used where
- Keep general-purpose fillers away from compartment walls
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.
