About our fire stopping in Canons Park
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. We work on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we are called in for most is unsealed penetrations discovered above suspended ceilings and fire stopping installed outside its tested range. A single leaking joint is often how a building in Canons Park 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.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email us and we’ll come back to it.

Keeping the joints sound
Once the work is signed off, these steps help:
- Ask the designer to confirm details early on refits
- Check risers and ceiling voids after each round of works
- Foam or ordinary sealant is never a fire-seal repair
- Report damaged or disturbed seals as soon as they’re spotted
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.
Signs you need fire stopping in Canons Park
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position and has to be removed.
Site and facilities staff are often the first to spot these:
- Unsealed joints where partitions meet the slab
- Penetration schedules that need working through
- Seals that don’t match their tested detail
- Fire sealant pulled out of the opening
For a unit at a centre such as Broadwalk Centre (0.6 miles east of Canons Park), penetration seals are worth checking after each shop fit.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint
- Is depth set with backing rod, or bond-breaker tape in shallow joints?

How the job changes by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
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.
Quoting for work in Canons Park
Quotes vary with the job. Expect it to depend on:
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
- Phasing around occupants
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Whether an asbestos survey exists
- Anything awkward about access or site hours
- Specification clauses that apply
- The postcode of the building
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. In Canons Park, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Move anything stored against the joints
- Point out parking and an unloading spot
- Send your site hours and access windows

Your questions answered
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Can you take on a job at a hospital such as Edgware Community Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How much does the work cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Fire stopping around Canons Park: points for this area
A number of hotels sit less than 2 miles from Canons Park. 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 London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
Workshops and IT rooms at colleges like Stanmore College (to the west of Canons Park) are re-serviced often, leaving penetrations to seal. Hospital estates such as Edgware Community Hospital, 0.8 miles to the east of Canons Park, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
