Questions we are asked in Granborough
Is Station Road Industrial Estate, near Granborough, within your area?
Yes, sites like Station Road Industrial Estate are within our area, along with the rest of Granborough. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is a smaller place like Granborough outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do the same rules apply to fire stopping in Scotland?
Scotland sets its own building regulations, with Technical Handbooks, and England uses Approved Document B. Either way, we install the specified sealant to its tested detail.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can you fire stop behind the services contractors?
Yes. Send the schedule or marked-up drawings and the specified product details. Work can run area by area behind the M&E trades keeping pace with the programme.
Will fire-rated sealant work on every penetration?
No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed, as set out by the designer.
Fire stopping for commercial buildings in Granborough
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Granborough. Most enquiries involve non-fire-rated filler around services and fire sealant pulled out of the opening, on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors. A specialist sealant contractor works differently from a general builder: in Granborough, that means joint design, primers and backing rod as standard.
A job near Granborough is usually planned around one visit, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why act early in Granborough
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Converted and older buildings near places like Granborough tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
After the work
Once the work is signed off, these steps help:
- Put resealing into every M&E and fit-out package
- Ask the designer to confirm details early on refits
- Report damaged or disturbed seals as soon as they’re spotted
- Foam or ordinary sealant is never a fire-seal repair
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Deciding what a wall or floor needs, which belongs to the designer
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping
If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Smaller jobs around Granborough can be grouped with others nearby. You’ll have a fixed quote before work starts.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.

Advice
What we’re called out for in Granborough
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
It’s worth sending us details if you spot any of the following:
- Fire stopping installed outside its tested range
- Fire sealant pulled out of the opening
- Unsealed openings around new pipes and cables
- Builders’ foam or ordinary silicone in compartment walls
For a unit at a site such as Station Road Industrial Estate, which lies north of Granborough, new power or data runs between office and warehouse can breach a compartment wall.

Penetration seals near Granborough
At about 45 miles from central London, Granborough is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a school such as Sir Thomas Fremantle School, penetration sealing fits best at the end of the summer works. Hotels like The Bell Hotel, 1.5 miles north of Granborough, are refurbished in phases, and each phase can open up compartment walls.
