Fire stopping for commercial buildings in Lake
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. The enquiries we see most involve old intumescent sealant that has split away and unsealed openings around new pipes and cables, across pipe penetrations, service gaps in risers and cable penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lake, preparation and product choice get the time they need.
Fire-rated sealing in a place like Lake is normally a single building at a time. Send the specification, drawings or photographs of the openings and we will quote to suit.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Common problems we fix in Lake
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
If one of these sounds familiar, it’s time for a closer look:
- Hidden openings found during inspections
- Head-of-wall gaps with no fire seal
- Fire stopping installed outside its tested range
- Penetration schedules that need working through
Large healthcare estates like Arthur Webster Memorial Hospital for Children, 1.2 miles south-west of Lake, change their services often, so penetration seals are worth checking after M&E work.

Honest limits
We check first that sealant really is the fix. It won’t put right:
- Walls or floors that aren’t fire-resisting to begin with
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.
Where we work in Lake
- Joints between fire-resisting walls and floors
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
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. Several jobs near Lake can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close
- Warn occupants and staff about the work
Request a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Advice
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Whether old sealant has to be cut out first
- Access and working height
- Working within restricted access windows
- Quantities, in metres or numbers
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- What the building is and how it’s used
- Any specification or named product
- Any dates the work must fit around
- Clear photographs of the problem areas
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Common questions from Lake clients
Can you work at a site such as Spithead Business Centre, by Lake?
Yes. We cover Lake and the area around it, including industrial estates, business parks and retail parks such as Spithead Business Centre. A few photos and the unit address let us price the work.
Is Lake too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Will you sign off the seals for us?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail.
Do you work in Scotland as well as England?
Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Where services cross fire walls in Lake
A 2-mile radius around Lake takes in plenty of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Offices at parks like Spithead Business Centre, 0.7 miles south-west of Lake, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. In a hotel such as Melville Hall Hotel, which lies north-east of Lake, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Lake is about 1 mile south-west of Sandown, in the Isle of Wight. If you are looking for fire stopping in Lake, we can help, as we do across the Isle of Wight. Our the Isle of Wight coverage takes in 125 places, from busy centres to rural villages. Our Portsmouth page has more on work in that area.
We take on service penetrations across the PO36 and PO37 postcode area, for business premises of every kind. If your site is on Lea Road, New Road and Percy Road or close by, we can quote for service penetrations. With the A3055 nearby, Lake is easy to get to with materials and equipment. Just outside Lake, we also work in Sandown (1 mile north-east), Alverstone (1 mile north-west), Queen's Bower (1 mile north-west), Shanklin (1 mile south) and Alverstone Garden Village (1 mile north-west). Further afield, our area takes in Newport (7 miles north-west), Ryde (5 miles north), Cowes (10 miles north-west), Ventnor (4 miles south-west), East Cowes (9 miles north-west) and Oakfield (5 miles north). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.
Near you in Lake
Recent enquiries here include premises near Sandown Bay Academy, The Old Comical pub and The Bay Church of England School and the streets around them. There’s a railway station in Lake itself: Lake station.

Not far away are Brading Down and Alverstone Mead.
What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones normally call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
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, and we work within it.
After the work
To get the most from the new sealant:
- Check with the data sheet before painting over fire sealant
- Ask the designer to confirm details early on refits
- Brief every trade that openings they make must be sealed
- Don’t let anyone top up a fire seal with the wrong product
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
