Fire stopping in Four Ashes, done properly
Facilities managers in Four Ashes 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 using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. The enquiries we see most involve fire-stopping items raised at inspection or handover and damaged fire seals in risers and voids, across pipe penetrations, service gaps in risers and joints between fire-resisting walls and floors. One point of contact handles commercial sealant work in Four Ashes from the first photos to the final walk-round, whether it’s one building or several.
A job near Four Ashes is typically planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building around Four Ashes, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Point out any areas we must not close
- Arrange parking or a loading space
- Send any specification or drawings in advance

Advice
Cost factors for service penetrations
These are the things that shape the price:
- How much existing material needs removing
- Site requirements such as inductions and permits
- How much there is to seal
- The size and state of each joint
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call 01277 525 020 or email us if you’d rather talk the job through.

Common questions from Four Ashes clients
Will you take on work at estates like Pilot Trading Estate, close to Four Ashes?
Yes, sites like Pilot Trading Estate are within our area, along with the rest of Four Ashes. Send details of the unit and the work through our quote form for a quick quote.
Can work at a site such as Buckinghamshire New University fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
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.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we’ll tell you when that applies.
Do you guarantee your work?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
What does an EI 60 rating mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep general-purpose fillers away from compartment walls
- Settle who seals which penetrations at the start of a project
- Treat an open penetration as a priority repair
- Ask which product is in place before decorating
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
Leave it or put it right?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these. For buildings around smaller places like Four Ashes, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Common problems we fix in Four Ashes
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Any of the following is a good reason to get the joints checked over:
- Damaged fire seals in risers and voids
- Service penetrations left open after M&E works
- Openings found when ceilings come down for a refit
- Unsealed joints where partitions meet the slab
Industrial units on estates such as Pilot Trading Estate, 2 miles south-west of Four Ashes, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
