Fire stopping in Surrey Canal
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, not a rule of thumb. If you have fire-stopping items raised at inspection or handover and seals disturbed by maintenance and left open, we can put it right, whatever the surface. Searching for sealant specialists in Surrey Canal? We’ve been sealing commercial buildings since 2005.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

What the job involves on each surface
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, and we tell you if the bundle exceeds what sealant covers.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, with no gaps along the run.
What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. In Surrey Canal, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. In Surrey Canal, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Tell us which areas need to stay in use
- Send your site hours and access windows
- Arrange parking or a loading space

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Questions about Surrey Canal
Will you take on work at estates like Orion Business Centre, close to Surrey Canal?
Yes. Estates, retail parks and business parks around Surrey Canal, Orion Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can work at a site such as Northeastern University London 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.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details for a fixed quote. Work can run area by area behind the M&E trades.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Is colour matching possible?
That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Where services cross fire walls in Surrey Canal
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We seal to the specification and the product’s tested detail, working within the building’s permits. The area within 2 miles of Surrey Canal holds a good number of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
Colleges such as Bellerbys College London, 1.3 miles to the east of Surrey Canal, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Shop fits in centres such as Surrey Quays Shopping Centre, 0.7 miles north of Surrey Canal, can bring new services through fire-resisting walls between units, which then need the specified seal. For an estates team at a campus like Northeastern University London, which lies north-west of Surrey Canal, summer M&E works are normally followed by a round of penetration sealing.
