Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Settle who seals which penetrations at the start of a project
- Report damaged or disturbed seals as soon as they’re spotted
- Don’t let anyone top up a fire seal with the wrong product
- Check with the data sheet before painting over fire sealant
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
About our fire stopping in Broadfields Estate
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. Most enquiries involve improvised or mixed-product fire seals and head-of-wall gaps with no fire seal, across pipe penetrations, joints between fire-resisting walls and floors and cable penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Broadfields Estate is the same: the right product in a properly prepared joint.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
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.

Penetration seals near Broadfields Estate
Broadfields Estate has three care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified. A 2-mile radius around Broadfields Estate takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
In a retail centre such as Broadwalk Centre (1 mile south of Broadfields Estate), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. For a site team at a college like Stanmore College (1.9 miles south-west of Broadfields Estate), fire-rated sealing is best scheduled after the summer works.

Signs you need fire stopping in Broadfields Estate
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Look out for the following:
- Fire-stopping items raised at inspection or handover
- Fire sealant pulled out of the opening
- Fire seals cut back for extra cables and never reinstated
- Improvised or mixed-product fire seals
Industrial units on estates such as Mill Yard Industrial Estate, 1.6 miles south of Broadfields Estate, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Will failed sealant be removed rather than covered?
- Are they CHAS accredited or on Constructionline?
- Do they follow the manufacturer’s priming guidance?
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Approving the work on behalf of building control
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.
Joints and surfaces we work on
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work
- Point out any areas we must not close

How the job changes by surface
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.
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.
Why deal with it now?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
Pricing service penetrations depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
